Components

This section provides a description of each of the major components that

comprise the imageRAID Series Storage System.

Front Bezel

The front bezel houses the Status LEDs, Drive LEDs, and alarm reset button. When

removed, the user has access to the disk drives. The front bezel can be installed or

removed without interruption to system activities.

Embedded within the front bezel is the electronic package that provides the

communication with the SES controller. The SES controller manages the signals to

the front panel through a smart interface. Power is applied to the front bezel

through the interface edge connector, where a control circuit monitors the bezel

for proper connection. When the bezel is properly installed and power is applied

to the enclosure, the bezel is immediately energized.

Refer to “Control and Monitoring” on page 18 for details on the monitoring

functions.

Removable Front Bezel

To remove the bezel and gain access to the disk drives, use a Phillips screwdriver

to release both bezel fasteners, then grasp and remove the bezel. The fasteners

rotate one-quarter turn clockwise to lock and counter-clockwise to unlock.

AC Power

The power system consists of two 350-watt hot-pluggable power supplies, each

with independent AC power cords and cooling fans. This power system provides

the enclosure with “N+1” redundant power. Each power supply has auto-switching

circuitry for use with either 100V or 240V AC systems.

Power Supply

Power is applied to the enclosure by pressing each of the two power supply

On/Off switches to their “On” position. A Power On LED located on each power

supply will be illuminated indicating that AC power has been applied. The front

bezels’ Power On LED will also be illuminated indicating that power has been

applied.

Each power supply also incorporates an amber general Fault LED. If the power

supply is installed and power is not applied to the power supply or the power

supply cooling fan fails, the Fault LED will illuminate, along with an audible alarm.

The front bezels’ Power Supply Status LED will illuminate green when both

power supplies are on and operating normally. If only one power supply is

operational, the Power Supply Status LED will be illuminated amber.

Each power supply has an AC Power Cord Module. The module has a power

cord bale incorporated into the design to secure the power cord once it has been

properly inserted. The bale prevents inadvertent disconnects.

AC Power



Cooling Fan Module

The cooling system consists of two high-performance (80-CFM) cooling fans

mounted in a single fan module which slides into a bay at the rear of the

enclosure. The design of the fan module provides for an easy-to-install user-

replaceable component in a live environment without interruption of service.

If any one fan should fail, cooling redundancy and efficiency are degraded. The

cooling fans and enclosure temperature are constantly monitored by the SES

processor for fault conditions. In the event of a fault condition the front panel Fan

Status LED will change from a green state to a solid amber state in the case of a fan

failure, or to a blinking amber green state in the case of an over-temperature

condition. In both cases an audible alarm sounds. The SES processor will also

provide notification data to monitoring software, such as StorView.

WARNING: Do not operate the enclosure for extended periods of time (greater

than 5 minutes) with the cooling fan module removed.

Cooling Fan Module

The enclosure has temperature sensors in three different areas, the drive bay, the

imageRAID Controllers, and the power supplies. There are several steps the storage

system performs to prevent component damage due to over temperature

conditions.

If the drive bay area reaches a temperature of 50°C (122°F) an audible alarm will

sound, the front panel Fan Status LED will toggle amber green, and the monitoring

software will post a warning message. These notifications give the user a warning

that some condition is causing the enclosure temperature to exceed the preset

value, and an action is required by the user to determine the cause and take

corrective measures. It may be due to a blockage of air flow or a low fan speed.

If any controller reaches a temperature of 65°C (149°F) an audible alarm will

sound, the front panel Fan Status LED will alternate amber and green, and the

monitoring software will post a warning message. If the temperature on any

controller continues to rise and reaches 71°C (159°F), the controller will flush its

cache and shutdown. If it is the only controller (Simplex mode) or the only

remaining controller (surviving controller from a failed over operation) then the

controller will also spin down the disk drives at this temperature.

If any power supply reaches 85°C (185°F) the power supply will shut down.

The SES Controller card has a firmware-based VT-100 interface which provides an

option to manage fan speed. This option provides a whisper mode fan operation

for noise sensitive environments. When enabled (default), and based on a set of

conditions, the software will manage the cooling fans RPM speed to maintain the

enclosure temperature while minimizing noise levels. Refer to “Enclosure Fan

Speed Control” on page 122 for more details on using this option.

A manual override of the fan speed control is available for special circumstance

environments. Referring to the illustration on the preceding page, two jumpers are

provided on the fan module printed circuit board to override the software control

of the fan speeds. This hardware setting routes full power voltage to the fans for

maximum operational speed, which is greater than the maximum speed set by the

automatic software control. This configuration is normally used when fan speed

noises are not an issue, and the ambient operating temperature is at or above 30°C

(86°F), thus ensuring that maximum available cooling is being provided.

The jumpers JP1 and JP2 by default are offset, which enables the automatic fan

speed control. The jumper JP1 controls Fan 0 and JP2 controls Fan 1. Placing the

jumper on both pins for each jumper will override the automatic setting and

configure the fans to maximum power.

Cooling Fan Module



SES Controller Card

WARNING: The SES Controller card is NOT HOT SWAPPABLE. You must POWER

DOWN the enclosure prior to removing or inserting this card.

The SES Controller card provides the built-in environmental and system status

monitoring. It also houses the switches for setting the drive spin up options. This

card is installed at the rear of the enclosure in the lowest slot below the two Disk

I/O cards.

The SES processors continuously monitor the enclosure for temperature status,

fan status, power supply status, and FC loop status. The processors are

responsible for reporting environmental and system status to the front bezel

LEDs/audible alarms, SES Monitoring software (VT-100), and external monitoring

software such as StorView.

SES Controller Card

At power up, the SES processors will read the switch settings and execute a

self-test. The cards’ firmware also contains software functions for enclosure

monitoring and management. This firmware is flash upgradeable using the SES

RS-232 Service port located on the card face plate. Refer to “Uploading SES

Controller Card Firmware” on page 119 for more details.

The SES protocol uses the drives installed in slots 1 and 7 to maintain its

communication link. You must install drives in both of these slots to ensure fault

tolerance for the SES communications link.

Disk I/O Card

The Disk I/O card is provided for drive channel expansion. By connecting daisy

chained IRF-JBOD enclosures to the Disk I/O cards additional enclosures and

drives can be added to your system. This card’s design incorporates an active

hub, and provides automatic loop regeneration (LRC) and port bypass. The loop

regeneration function will “heal” the FC-AL (Fibre Channel-Arbitrated Loop)

when components become disconnected or faulty.

There are two Disk I/O cards installed at the rear of the enclosure adjacent to the

cooling fan bay. The upper Disk I/O card provides the connection to the “Loop

0” side of the disk drives, and the lower Disk I/O card provides the connection to

the “Loop 1” side of the disk drives.

Each Disk I/O card supports Small Form-Factor Pluggable (SFP) cages to accept

either optical or copper transceivers. They are designed to support NCITS T11

Fibre Channel compliant devices at speeds of 1.0625 Gb per sec or 2.125 Gb per

second. The speed is set through a hardware jumper (JP4) located on the Disk

I/O card. Set the jumper on one pin only or offset for 2Gb mode. If you need to

configure the system for 1Gb mode, position the jumper to both pins. An LED on

the card’s faceplate will illuminate to indicate the 2 Gb mode.

NOTE: The Disk I/O cards are universal and can be interchanged.

Host I/O Card

The Host I/O card provides the fibre connectivity from the host computer(s) to

the Fibre Channel controller ports. This hot swappable card is designed to

support NCITS T11 Fibre Channel compliant devices at speeds of 1.0625 Gb per

sec or 2.125 Gb per sec. Each card has two SFP cages that house optical or

copper SFP transceivers. They are labeled “H0” and “H1.”

The Host I/O cards are installed at the rear of the enclosure, above the controller

slots. The right Host I/O card provides connectivity to controller’s port 0 (C0P0 and

C1P0) of both controllers, and the left card provides connectivity to controller’s

port 1 (C0P1 and C1P1) of both controllers.

RAID Controllers

The imageRAID Series Storage System is designed to house one or two hot

pluggable imageRAID Controllers. They are next generation dual port

high-performance 2 Gb/second Fibre Channel-to-Fibre Channel RAID controllers

supporting RAID levels 0, 1, 5, 10, and 50.

There are two models of the imageRAID Controller. The base imageRAID model is

a FC-FC RAID Controller with a single RISC processor. The imageRAIDXP model is

the base controller plus a co-processor.

The controllers are designed for “I/O Intensive” and “Bandwidth Intensive”

applications, providing simplex (stand-alone) and duplex (active-active)

configurations designed for existing and future Fibre Channel topologies. In

simplex operations, the controller operates autonomously. In duplex

configurations, the two controllers operate as a pair. In the event one controller

fails, fault tolerance is maintained via hardware failover allowing either controller to

take over the operations of the other controller.

Fibre Channel-Fibre Channel imageRAID Controller

Each controller has two Fibre Channel ports and two Fibre Channel disk ports for

a “2x2” configuration (dual host-dual drive). In duplex configurations, it can

process up to 80,000 I/O’s per second (IOPS). The active-active pair of RAID

controllers can feed data to SAN nodes at a sustained rate of 320 MB/sec, and

process RAID 5 write operations at 220 MB/sec.

RAID Controllers



The core processor of the controller is based on an Intel XScale™ RISC processor

running at 600 MHz. The processor has integrated instructions and data caches

that allow for the most frequent instructions to be executed without having to

access external memory. Coupled with the micro kernel, it processes commands

and I/O’s at extremely high rates.

The processor’s companion chip implements dual independent 64-bit 66MHz PCI

busses. Devices on these busses have independent access to the shared 512 MB

of SDRAM. Also, an integrated XOR accelerator is included for RAID 5 or 50

parity generation.

The imageRAID Controller disk drive interface uses QLogic ISP 2312 dual Fibre

Channel controllers which takes full advantage of the dual fibre loops on each

disk drive. The controller’s host interface also uses QLogic ISP 2312 dual Fibre

Channel controllers which provides two independent ports for host connectivity.

Each port can operate at either 1 Gb/sec or 2 Gb/sec, and the controller will

automatically detect the correct rate. The ports are sometimes referred to as “Host

Loops.”

Located on the controller face plate are Activity, Link and Status LEDs. Refer to

the table below and the illustration on the following page for descriptions for

each LED.

NOTE: The “TXRX-LNK” and “1K-10/100” LEDs are provisions for future options.

Battery Backup Unit

The main board of the imageRAID Controller includes battery control circuitry for

a single cell Lithium Ion battery along with a battery pack mating connector. The

main purpose of battery backup is to maintain the cache memory during brief

power interruptions, but is capable of maintaining the memory content for

several hours, depending on the type and size of the memory.

Battery Backup Unit



The battery control circuitry has constant current, constant voltage (CCCV) charger.

The battery charger provides a maximum 250mA charge current. When the charge

current falls below 16mA, the charger determines that the end of charge has been

reached, generates an end of charge indication and shuts itself off. If the battery

voltage drops below 3.0V, a complete battery discharge is indicated.

The battery control circuitry includes a battery safety circuit. The safety circuit

protects the battery by limiting the over-voltage to 4.3V, the maximum discharge

current to 3A for catastrophic events, and the minimum battery voltage to 2.35V. If

any of these conditions exist, the safety circuit disconnects the battery. These

conditions will only exist if there is a hardware fault present, and would never be

seen under normal operating conditions. In addition, the battery pack utilized, part

number 44-9-95611001, includes a resettable polyfuse that trips when the current

exceeds 700mA at room temperature. This protects the 1 amp rated connector

when for example a partial short exists caused by aa component failure.

Lithium Ion batteries have no requirement for conditioning, even after partial

discharges. The current battery pack utilizes a Renata ICP883448A-SC cell, with a

nominal capacity of 1150mAh. For a completely discharged battery, the charge time

is approximately 5 hours. Under lab conditions, current draw was measured for

different configurations of memory. The table below shows the results of those

tests, and the expected backup time is indicated for the specified memory

configuration. The table shows the absolute maximum backup time calculated from

the current draw measurements. The “Expected Safe Backup Time” is the absolute

maximum de-rated by 50% to account for different operating temperatures and

capacity reduction due to battery charge/discharge cycles. This is the time that

should be used when developing a system level power backup plan.

Control and Monitoring

An integral part of the imageRAID Series Storage System is its control and monitor

capabilities.

The SES processors provide monitoring data for the enclosure environmental

conditions such as enclosure temperature, cooling fans, power supplies, and FC

Loop status. This data is reported to the monitoring system to provide LED and

audible alarm notifications. This monitored information is also communicated to

external monitoring software.

Refer to “VT-100 Interface Enclosure Monitoring” on page 116 for complete

details.

Front Bezel LEDs and Reset Button Identification

The imageRAID Controllers provide monitoring data for its environmental

condition and logical arrays. They communicate that data to the front bezel LEDs,

third-party configuration and monitoring software such as StorView, and the

VT-100 firmware-based interface for management and monitoring. (Refer to the

software user’s guide for configuration, management, and monitoring of the

controllers and logical arrays.)

The imageRAID Series incorporates a “One-Touch Annunciation Configuration

Display” which provides LED readout of the fan control, Host I/O and Disk I/O

speed modes, Disk I/O and Host I/O card presence and controller presence. Refer

to “One-Touch Annunciation Configuration Display” on page 115 for more details.

Status Indicator LEDs

The Status Indicator LEDs comprise the Power-On LED, Channel Status LED,

Power Supply Status LED, and Fan Status LED. These series of LEDs are grouped

on the right side of the front bezel directly above the Alarm Reset button. The

following is a description of each of these LEDs.

Power-On LED

The Power-On LED signifies that the enclosure is powered on and will be

illuminated green when power has been applied.

Channel Status LED

The Channel Status LED will illuminate green to indicate a valid status of the FC

loop or a logical array. Should an error occur, the LED will change to amber.

Power Supply Status

The Power Supply Status LED indicates the condition of the power supplies. The

LED will illuminate steady green when both power supplies are functioning

normally and will change to amber if one of the power supply should fail or is

turned off.

Fan Status

The Fan Status LED indicates the condition of the cooling fans. The LED will

illuminate green when both fans are functioning normally and will change to

amber if any of the fans fail.

Status Indicator LEDs 19

Drive LEDs

The Drive LEDs are located on the left side of the front bezel in between the

ventilation ribs, and comprise the Drive Status LEDs and Drive Activity LEDs. The

Drive LEDs are grouped in pairs and are in the general location of the disk drive

slot. There are 12 Drive Status and 12 Drive Activity LEDs, one group for each

disk drive.

Refer to “Drive LEDs” on page 110 for detailed information.

Audible Alarm

An audible alarm will sound when any of the enclosure’s component status

changes to an abnormal state. To silence the alarm, press the Alarm Reset button

located on the front bezel. The corresponding alarm’s LED will remain

illuminated until the condition returns to a normal state.

Chapter 2


Topologies and Operating Modes

This chapter provides an overview of the supported operating modes and

topologies. This information should provide you with an understanding to make

the best choices for the optimum configuration that compliments your storage

system solution.

Essentially there are two operating modes available: Simplex and Duplex. The

IRF-1Sxx-xx or IRF-1Dxx-xx models with their single RAID controller support the

simplex operating mode, and the IRF-2Sxx-xx or IRF-2Dxx-xx models with their

dual RAID controllers support the duplex operating mode.

Operating Mode Overview

These operating modes allow you to configure the enclosure’s drives and RAID

controller(s) to support a variety of host environments topologies.

� Simplex – In this operating mode, the enclosure is configured as a RAID

storage system with its single RAID controller operating in a stand-alone

configuration. This operating mode supports dual port topologies.

� Duplex – In this operating mode, the enclosure is configured as a RAID

storage system with dual RAID controllers operating in an active-active or

redundant fault-tolerant configuration. This operating mode supports

Multiple Port Mirrored topologies.

21

Chapter 2 - Topologies and Operating Modes

22


Simplex Mode

The simplex operating mode uses a single RAID controller solution that provides

a limited level of redundancy. With its dual port topology, the controller also

provides dual active ports that increases the bandwidth capabilities. Essentially,

there are four supported topologies for this operating mode:

� “Dual Port Single Host Connection” on page 22

� “Dual Port Single Host Dual Connection” on page 23

� “Dual Port Multi-Host Single Connection” on page 24

� “Dual Port Multi-Host Dual Connection” on page 25

Dual Port Single Host Connection

This topology provides an entry-level RAID storage solution for single ported HBA

host system. It offers the following advantages: an initially lower cost system to

deploy and is a simple direct attached solution. It has several disadvantages:

multiple points of failure (host server, host HBA, controller, and data cable), and it

has limited bandwidth capabilities due to its single Fibre loop (200 MB/sec).

Switch 2 configures the enclosure for the imageRAID Controller.

Switch 4 provides the link between the Host I/O card “H0” and “H1” ports to

the same Fibre loop.

Dual Port Single Host Dual Connection

This topology provides an entry-level RAID storage solution for dual ported host

systems with multiple paths to the storage. It offers the following advantages: an

initially lower cost system to deploy, multiple paths from host which can

maximize controller bandwidth, and it provides multiple paths for optional

upstream failover. It has several disadvantages: the RAID Controller is a single

point of failure, it requires two single ported HBAs or a dual ported HBA, and if

upstream path failover is implemented then additional software is required.

systems. It offers the following advantage: clustered storage between multiple

host system (no requirement for external hubs or switches). It has a few

disadvantages: the controller and the single fibre loop are single points of failure,

for clustering operations third-party clustering software is required and it also has

limited bandwidth performance due to a singe Fibre loop (200 MB/sec).

Duplex Mode

The duplex operating mode is a dual RAID controller solution providing a

redundant controller or an active-active RAID storage solution. Beginning with a

minimum level redundancy solution it can be configured to provide the most

robust redundant RAID storage solution. This operating mode supports the

Multiple Port Mirrored topology.

In a Multi-Port topology, all ports are active and provide transparent hardware

failover and failback operations. It provides for higher host bandwidth

capabilities with each port connected to an individual fibre loop.

During controller failure, internal HUB circuitry on the Host I/O cards

automatically detect a failure and connects the incoming Fibre loops together so

that the surviving controller immediately starts processing host commands.

There are essentially five supported topologies available for the Duplex mode:

� “Multi-Port Mirrored Single Host-Single Connection” on page 27.

� “Multi-Port Mirrored Single Host-Dual Connection” on page 28.

� “Multi-Port Mirrored Dual Host System-Quad Connection” on page 31.

� “Multi-Port Mirrored SAN Attach Single Switch Connection” on page 32.

� “Multi-Port Mirrored SAN Attach Dual Switch Connection” on page 33.

NOTE: Some Operating Systems, such as HP-UX, when connected to a fabric

require that you set the Controller Parameter option “Host Different

Node Name” to enabled. This will cause the controller to present a

different Configuration WWN for each controller port. Otherwise if the

same WWN is reported on both ports, one port would be blocked by the

OS. Refer to the VT-100 or StorView Software Guide for specific

information on this option.

Multi-Port Mirrored Single Host-Single Connection

This topology provides an redundant RAID storage solution for single host systems

with one fibre port where a fault-tolerant disk subsystem storage is required. It has

the following advantages: initial lower costs, redundant RAID controllers, and

transparent failover and failback operations. It has several disadvantages:

performance limited bandwidth capabilities due to the single Fibre loop, and the

host system, host HBA and the single fibre loop are single points of failure.

Multi-Port Mirrored Single Host-Dual Connection

This Multi-Port Mirrored topology provides an active-active RAID storage solution

for single host systems with dual Fibre ports where fault-tolerant RAID disk

subsystem storage is required. It has several advantages: redundant active-active

controllers, and transparent failover and failback operations, LUN isolation (LUNs

appear only once to the host OS), and dual connections for higher performance

independent access to assigned LUNs.

It has two disadvantages which are the host HBA and the single fibre loop which

are single points of failure.

Example of Multi-Port Mirrored in Fail-Over Mode

The following illustration demonstrates how the ports failover in the Multi-Port

Mirrored topology.

Switch 6 which enables automatic internal hub failover when a controller failure

is detected and also controls the logical function of switch 4. When a controller

failure is detected, the logic circuit will close connecting the “H0” and “H1” ports

on the Host I/O card, regardless of the physical position of switch 4.

As shown below even though switch 4 is disabled (down position) when the

controller failed, switch 6 logically enabled that circuit providing alternate paths

to the surviving controller ports.

Multi-Port Mirrored Dual Host System-Single Connection

This topology provides one of the more robust active-active RAID storage

solution for dual host systems with single Fibre ports. It has the following

advantages: high availability and high-performance where each host requires

access to all LUNs, redundant active-active RAID controllers, transparent failover

and failback, and shared storage between two host systems.

Its disadvantage is the single fibre loop which becomes a single point of failure.

Daisy-Chain JBOD Enclosures

Single Bus Dual-Loop Mode

The IRF-BOD enclosure is used as the daisy-chain enclosures to expand the

number of drives available to the imageRAID systems up to the limit of 96 disk

drives. The JBOD enclosure is configured as a Single Bus Dual-Loop system, where

the drive plane is a continuous 12 (twelve) drive single bus dual-loop FC-AL

configuration. The jumper, (JP3) on the Disk I/O card, should be offset (default

position) or installed on one pin only which enables this option. When enabled,

it also activates the internal hubs and provides the continuous FC loop.

LUN Mapping

The RAID Controller has extensive support for LUN Mapping or SAN LUN

Mapping (SLAM). A LUN can be mapped to particular host HBA or to a particular

host HBA port. Up to 512 LUN mappings can be created, with a 2 TB per LUN

limitation. Online LUN addition and deletion is supported.

LUN Mapping allows multiple hosts and operating systems with exclusive access

to certain areas of the storage, without requiring host software for management.

Additionally, an internal LUN can be presented to a host system as a different

LUN number, simplifying multiple systems setup.

Alternate Path Software

This is a software tool that manages multiple paths between the host operating

system and LUNs. The software manages the multiple paths by detecting

duplicate disk objects that represent a single LUN. It then designates one disk

object as the primary disk object with a primary path, while the other is

designated the secondary disk object with an alternate path. If the primary path

becomes inaccessible, the software redirects the data to the secondary disk object

through the alternate path, preserving the LUN.

This redirection is known as path failover. The software continuously tries to

access the failed path by issuing a SCSI Test Unit Ready command. A good status

returned indicates the path is repaired and restored to operational status. The

software automatically redirects data back to the primary path and primary disk

object. This restoration of data transfer is known as path failback.

Fibre Channel Media Types

Optical transceivers are provided with the enclosure. Fibre optical transceivers

provides a more reliable media and supports distances up to 300 meters between

nodes.

A Word about Clustering

Minimizing Downtime for Maximum Data Availability

So-called open systems, such as Windows servers, just don’t provide the level of

availability that IS managers are familiar with on mainframes. A partial solution to

this problem is server clustering.

Clusters consist of two or more loosely coupled systems with a shared-disk

subsystem and software that handles failover in the case of a node (host) failure.

In most cases, hardware/software failover is performed automatically and is

transparent to users, although users will experience performance degradation as

processing is shifted to another cluster node. In some cases this failover can

occur in a matter of seconds.

High availability of data and applications is by far the most compelling reason to

go with clustering technology. For example, the accepted rule is that stand-alone

UNIX systems can provide 99.5% uptime. Adding a RAID subsystem can increase

the uptime to 99.9%. The goal of clustering is 99.99% availability.

Beyond clustering, fault-tolerant systems can provide 99.9999% uptime. At the

high end, continuous-processing systems offer virtually 100% uptime.

Although the increase from 99.5% to 99.99% availability may seem insignificantly

small, it adds up in terms of minutes per year of downtime. For example,

assuming a 7x24 operation, 99.5% uptime translates into 2,628 minutes — or

more than 43 hours of downtime per year. In contrast, 99.99% uptime translates

into less than one hour (52 minutes) of downtime per year.

Availability figures relate primarily to unplanned downtime. But the advantages

of clusters in terms of planned or scheduled downtime are even more significant.

If you figure two to sixteen hours per month for a server in a large shop.

Planned downtime requires shutting down stand-alone systems entirely. Result:

100% loss of processing for the duration of the downtime. But, with cluster, you

can shut down one node and off-load the processing to other nodes in the cluster

with no interruption of processing.

A Word about Clustering 37


38


High availability is not the only benefit of clustering. In some cases, users may

see advantages in the areas of performance, scalability, and manageability. In

reality, you can expect a 1.6x (80% efficiency) to 1.8x (90% efficiency)

performance increase as you go from one node to two nodes. Going from one

node to a four node cluster generally yields a 2.5x or 3x performance boost.

However, the cluster performance is application dependent. For example, READ

operations may yield a 1.8x performance increase going from one to two nodes,

but in a WRITE intensive application, you may only see a 1.4-1.6x improvement.

Although clusters seem to be relatively simple, they involve complex technology

that can be implemented in a variety of ways. The number of nodes supported

and type of interconnection used, and a number of other features differentiate

cluster implementations. One area of implementation is the manner in which

distributed lock manager is implemented. Some perform this at the user level and

others in the kernel, with the latter enhancing performance.

In addition to the differences of features you should consider the following:

Does the cluster:

• have the ability to hot load new nodes without bringing down the whole cluster?

• provide automatic or manual failover?

• load balance?

• use a journalized file system?

• provide a fast cluster failover?

• allow for the nodes to be geographically located?

Storage System Detailed Installation

This section describes preparing and installing the enclosure(s) into the rack

cabinet or the enclosure into its tower stand “Installing the Storage System into

the Tower Stand” on page 45.

After installing the hardware components, go to the “Operating Mode

Configuration and Cabling” section, and set the SES Controller card switches as

described and cable the enclosure(s) for your selected topology.

Installing the Storage System Enclosure into the Rack Cabinet

1 Install the storage enclosure(s) into the rack cabinet.

Select an appropriate location within your rack cabinet. You should consider

the location of the enclosure(s) in relationship to each other to ensure that the

cables will easily reach between enclosures when installing multiple

enclosures.

CAUTION: The power supplies should be removed prior to installing the

enclosure. The enclosure chassis could be damaged during

installation due to the added weight of the power supplies.

2 Remove each enclosure from its shipping carton and inspect for obvious

damage. Place the enclosure on a flat surface to work from.

3 Remove the front bezel from the accessory box and store it in a location

where it will not be damaged. It will be installed later in the installation

procedures.

4 Remove the power supplies.

From the rear of the enclosure, remove a power supply by grasping its

handle and pressing in on the release latch with your thumb as you pull the

power supply from the enclosure. Repeat for the other power supply.

5 Locate the mounting hardware in the accessory kit (mounting rails, screws,

and nuts – on some rack installations you will use cage nuts and on some

racks they will be standard nuts).

NOTE: It will be helpful to have an assistant available during the installation.

6 Lift and secure the enclosure into the rack cabinet.

Operating Mode Configuration and Cabling

In this section you will find the instructions for setting the SES Controller card

switches and Host I/O card switches, followed by illustrated instructions to setup

and cabling the specific operating mode topology.

SES Controller Card Switch Setting Overview

A word about Fibre Channel device IDs. Under the FC protocol, device IDs can

be generated in several ways: hard addressing, previous addressing, and

negotiated addressing. RAID controllers prefer hard device addressing which

ensures that the device ID will always be the same. It is set using a specific set of

switch settings. Previous addressing is a method that allows the system to

determine whether or not the device has had a previous address ID assigned to it

and will attempt to use that ID, if it is not available it will assign a new ID. And

negotiated addressing occurs when a hard address or a previous address do not

exist and it will then negotiate the bus for a new device ID. The disadvantage of

negotiated device IDs is that there is a potential liability of the device ID

changing due to reconfiguration and therefore could cause potential problems for

the RAID controller’s array drive members.

The SES Controller card has a set of switches which configures the enclosure

base address and assigns a device ID to the drive slots, and sets the drive spin-up

options. The disk drive slot IDs are determined by the first three switches,

labeled AD0, AD1, and AD2. They establish a base enclosure hard address and

assign the drive slots each with a pre-determined set of IDs.

Switches 4, 5 and 6 are spares, and switches 7 and 8 set the drive spin-up

options.

The table on the following page displays the available device ID ranges for each

series of switch settings. Following the diagram, is an illustration which depicts

the drive slot layout within the enclosure.

Operating Mode Configuration and Cabling



Refer to the sample illustration to see how an ID range is assigned.

Device ID Ranges

Drive Slots and Sample IDs Assigned

NOTE: Odd numbered drive slots are assigned to Channel 0 and even numbered

drive slots are assigned to Channel 1 of the RAID Controller. This allows

for improved performance throughput.

1 Locate the switches on the SES Controller card and set them as described for

the specific range needed.

2 If you have daisy-chain expansion enclosures, set their SES Controller card

switches to the next available range of IDs, as desired.

For example, if you have two enclosures installed, the first is a imageRAID

IRF-1Dxx-xx with a single RAID Controller (master) and the second

daisy-chain enclosure is a IRF-JBOD system (slave). Set the master RAID

enclosure to IDs 0 - 11, and the daisy-chain slave enclosure to IDs 16 - 27.

SES Controller Card Switch Setting Overview



Simplex Mode (imageRAID IRF-1Sxx-xx/IRF-1Dxx-xx)

The basic simplex (Stand-Alone) operating mode provides a single enclosure

with a single RAID Controller solution. This mode provides solutions for single or

multiple host environments to achieve a fault-tolerant disk storage solution. It has

provisions for drive channel expansion through daisy-chaining of IRF-JBOD

enclosures, and/or upgrading to a imageRAID IRF-2Dxx-xx model by adding an

additional controller for duplex operations.

CAUTION: The bus speed must be set to the same setting between the disk

drives and the Disk I/O card(s), and the host system HBAs (BIOS

setting) and the Host I/O cards. For example, if you are using 2 Gb

drives, the Disk I/O cards must be set to 2 Gb mode. If your host

system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must be set

to 1 Gb mode.

NOTE: Split-bus mode is not supported when a RAID Controller is installed.

Stand-Alone Dual Port Single Host Configuration

1 Set the jumper (JP4) on the Disk I/O card to configure the bus speed mode.

Loosen the two captive fastener screws on the Disk I/O card and pull it from

the enclosure using the fastener screws. Locate the jumper JP4 and position it

for the desired speed setting, (installed on one pin only for 2 Gb mode and

on both pins for 1 Gb mode).

Duplex Mode (imageRAID IRF-2Sxx-xx/IRF-2Dxx-xx)

The basic duplex operating mode provides a single enclosure with dual RAID

Controllers. The two controllers operate in an active-active configuration, where

both controllers are actively processing data. This greatly improves the overall

system performance and provides the most robust system redundancy.

The supported operating mode is Multi-Port Mirrored, where all controller ports

are active and connected to individual fibre loops. It provides transparent

hardware failover and failback. During a controller failure, internal HUB circuitry

located on the Host I/O cards automatically connects the incoming Fibre loops

together and the surviving controller immediately starts processing host

commands.

This duplex mode supports several cabling configurations. The configurations

demonstrate attachments to a single enclosure and multiple enclosures.

CAUTION: The bus speed must be set to the same setting between the disk

drives and the Disk I/O card(s), and the host system HBAs (BIOS

setting) and the Host I/O cards. For example, if you are using 2 Gb

drives, the Disk I/O cards must be set to 2 Gb mode. If your host

system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must be set

to 1 Gb mode.

NOTE: Split-bus mode is not supported when a RAID Controller is installed.

Upgrades

At some point you may have a need to upgrade your storage system to increase

the storage capacities and/or the RAID capabilities. The imageRAID Series

Storage System provides you with this ability to meet your expanding data

storage requirements.

The RAID controllers support a feature know as “drive roaming,” where the

controllers can keep track of which drive belong to which logical arrays. In the

event the drives’ enclosure is changed or the drives are moved to another

enclosure attached to the same set of controllers, the arrays will not be lost or

damaged.

The upgrade process is relatively easy, refer to the “Operating Mode Configuration

and Cabling” section for the new topology for your configuration. Install the new

components, set the SES Controller Card switches, the Host I/O card(s) switches

and the Disk I/O cards jumpers for the new configuration settings, then cable the

storage system enclosures as indicated.

Upgrades



Powering On the Storage System

After you have the system setup and installed, you are ready to power on the

storage system enclosure(s).

NOTE: Ensure that the data cables, power cables, or other objects are not

obstructing the air flow exiting the cooling fan module.

1 Locate the power supply On/Off switches at the rear of the enclosure(s).

2 Press each power supply switch to its “On” position. (Repeat this step for

each of the attached storage system enclosure(s).)

All enclosures will perform a power on self test during their initial start.

3 Next power on the host computer(s) which are connected to the storage

system.

Powering Off the Storage System

NOTE: If you are planning to completely shut down the entire system, power

down the host system first.

1 If applicable, ensure that the controller(s) have been gracefully shut down.

2 Press each enclosure’s power supply On/Off switches to their “Off” position.

3 Repeat the above step for each of the attached storage system enclosure(s).

Powering On the Storage System 107

Powering Off the Storage System

Chapter 4


Managing and Monitoring

In this chapter you will find information about using the enclosure’s onboard

monitoring systems. It also contains the procedures to update the enclosure’s SES

Controller card firmware.

Using a VT-100 terminal (or emulation) connected to the SES RS-232 Service port

provides an interface to the enclosure’s monitoring system and firmware. If you

are using StorView, refer to the StorView software guide for details on the

GUI-based monitoring and how the interface works in conjunction with the

enclosure monitoring components.

You should monitor your storage system regularly to ensure that the disk drives,

controllers, arrays, and enclosure components are working properly. The front

bezel LEDs provide monitoring information for the enclosure components, fan

status, disk drive status, controller status, and array monitoring. The “One-Touch

Annunciation” Configuration Display provides information about switch settings,

Host I/O card, Disk I/O card, and controller presence, all from the touch of the

reset button.

Enclosure Component Monitoring

This section covers notifications provided by the front bezel LEDs and a detailed

explanation of the “One-Touch Annunciation” Configuration Display system.

As part of the monitoring notifications, an audible alarm works in conjunction

with the enclosure’s front bezel LEDs, and will sound an alert for any fault that

occurs with an enclosure component, logical array, or disk drive. To silence the

alarm, simply press the Alarm Reset button.

109

Chapter 4 - Managing and Monitoring

110



The Status Indicator LEDs located above the Alarm Reset button, comprise the

Power-On LED, Channel Status LED, Power Supply Status LED, and Fan Status

LED. The following are descriptions of each of the LEDs.

Power-On LED

The Power-On LED signifies that the enclosure is powered on and will be

illuminated green when power has been applied.

Channel Status LED

The LED will indicate the status of the logical array(s), when a RAID Controller is

installed. It will indicate a failed controller by alternately blinking green and

amber when a failure does occurs. It will change to amber when the system

detects a problem with a logical array.

Power Supply Status

The Power Supply Status LED indicates the condition of the power supplies. The

LED will illuminate steady green when both power supplies are functioning

normally and will change to amber if one of the power supplies should fail or be

turned off.

A failed power supply can also be identified by the illumination of the amber

“Fault” LED located on the individual power supply.

Fan Status

The Fan Status LED indicates the condition of the cooling fans. The LED will

illuminate green when both fans are functioning normally and will change to

amber if either of the fans fail.

Drive LEDs

The Drive LEDs are located on the left side of the front bezel between the

ventilation ribs and comprise the Drive Status LEDs and Drive Activity LEDs. The

Drive LEDs are grouped in pairs and are in the general location of the disk drive

slot.




These Drive LEDs assist with identifying array status, the presence of a drive in a

drive slot, and which drives are experiencing I/O activity.

The Drive Status LEDs are also used for the “One-Touch Annunciation”

Configuration Display system. Pressing and holding the Alarm Reset button will

cause these LEDs to display the Host I/O and Disk I/O card speed settings, and

the presence of Host I/O, Disk I/O cards, and controllers. Refer to “One-Touch

Annunciation Configuration Display” on page 115 for more information.

Front Bezel LED Identification

Drive Status LEDs

There are twelve Drive Status LEDs. The Drive Status LED is the left LED of each

pair of Drive LEDs. This LED will illuminate steady green when a drive is present

in the slot and powered on. If a drive is not present the LED will be off.

Drive Activity LEDs

There are twelve Drive Activity LEDs. These LEDs will flash indicating a specific

drive is being accessed, either during read or write activity. The Drive Activity

LED is the right LED of each pair of Drive LEDs.

Drive Carrier LitePipes

On each disk drive carrier are “LitePipes.” They are located on the lower right side

of each drive carrier. The LitePipes present some of the information provided by

the front bezel Drive LEDs, that is, drive activity information and drive fault

(failure) or data rebuilding notifications when the front bezel is removed.


Audible Alarm

An audible alarm will sound when any of the enclosure’s component condition

changes to an abnormal state. To silence the alarm, press the Alarm Reset button

located on the front bezel. The corresponding LED will remain illuminated until

the condition returns to a normal state.

VT-100 Interface Enclosure Monitoring

Another feature of the imageRAID Series Storage System is the ability to monitor

the system through a VT-100 terminal interface. The firmware based monitoring

program allows users to view storage system component status and information

about the firmware. You may access this program by connecting a VT-100 terminal

to the SES Controller card RS-232 Service port.

To access the monitoring program:

1 Connect one end of the null-modem serial cable to the RS-232 Service port

located on the SES Controller card.

Connecting the RS-232 Cable

NOTE: The cable is a female-to-female DB-9 null-modem serial cable. Refer

to “Null-Modem Cable Specifications” on page 159 for cable

specifications.

2 Connect the other end of the cable to either a host system’s RS-232 serial

communication port or a VT-100 type terminal.

3 On the host system, run a terminal emulation program or start the terminal.

4 Verify the communication parameters are as follows:

• 9600 Baud

• 8 Data bits

• 1 Stop bit

• None (parity)

• Flow Control Off

5 At the screen cursor, type <Control-E>. The Enclosure Terminal Utility menu

will appear.

Uploading SES Controller Card Firmware

The following information describes the procedures to upload new firmware to

the SES Controller card. The preferred method is to take the enclosure off-line

first, then perform the upgrade. This prevents bus reset errors.

1 Connect one end of the null-modem RS-232 cable to the RS-232 Service port

located on the SES Controller card.

Connecting the RS-232 Cable

NOTE: The cable is a female-to-female DB-9 null-modem serial cable. Refer

to “Null-Modem Cable Specifications” on page 159 for cable

specifications.

2 Connect the other end of the cable to either a host system’s RS-232 serial

communication port or a VT-100 type terminal.

3 On the host system, run a terminal emulation program or start the VT-100

terminal.

Enclosure Fan Speed Control

The SES Controller card has a firmware-based VT-100 interface which provides an

option for fan speed control. This allows the user with the choice to enable or

disable the automatic control feature. It provides for more efficient management

of the cooling fans and a whisper mode fan operation for noise sensitive

environments where it significantly reduces the noise created by the cooling fans

running constantly at full speed. Under normal conditions it is not necessary to

run the cooling fans at full speed.

When this option is enabled, the software will control the RPM of the cooling

fans based on enclosure temperature parameters and its installed component.

For example, if any one or a combination of the following occurs, the cooling fan

RPMs will be set to the maximum software controlled RPM: a disk drive is

removed from any of the drive slots 4 through 9, a power supply is removed, one

of the cooling fans in the cooling fan module fails, a temperature sensor fails, or

a SES processor fails.

Fan Speed Setup Screen

A manual override of the fan speed control is available for special circumstance

environments. Referring to the illustration on the following page, two jumpers are

provided on the fan module printed circuit board to override the firmware

control of the fan speeds.

Enclosure Fan Speed Control



This hardware setting provides full voltage to the fans for maximum operational

speed, which is greater than the maximum speed set by the automatic software

control. This configuration is normally used when fan speed noises are not an

issue, and the ambient operating temperature is at or above 30°C (86°F), thus

ensuring that maximum available cooling is being provided.

Cooling Fan Module

The jumpers JP1 and JP2 are by default are offset which enables the use of the

automatic fan speed control. The jumper JP1 controls Fan 0 and JP2 controls Fan 1.

Placing the included jumper on both pins of each jumper will override the

automatic setting and set the fans to maximum power.

At the bottom of the screen a series of “C” characters will be displayed.

5 When the “C’s” appear, click the Transfer pull-down menu selection and

choose Send File. Then select the “1K Xmodem” protocol.

6 Click the browse button and locate the new Firmware file and click “Send.”

The firmware file will be named similar to “W_2_10.bin.”

NOTE: Ensure that the protocol “1K Xmodem” is selected. The “1K

Xmodem” protocol is preferred due to its superior error detection

(CRC vs. checksum).

From the send screen you can monitor the progress of the download. You

can safely stop the transfer without affecting your existing firmware any time

during the transfer until it has been completed. The upload does not

overwrite the firmware during the upload process, it writes the new code into

RAM until completed, then copies the new firmware code to the EEPROM

after verification.

If you elect to stop a download in progress, ensure that the stop (abort)

command was completed by clicking the Cancel button.

Common Fibre Loop/Bus Problems

Fibre loop or bus problems can usually be attributed to cabling issues, transceivers,

speed mode setting or possibly a faulty Disk I/O or Host I/O card. Refer to the

chart below to review troubleshooting and fault isolation procedures to assist you

in identifying the suspect component or problem, and the possible solutions.


Host I/O Card “H0” or “H1” Link LED not illuminated.

Bus speed mode setting not

in agreement.

1) Verify that:

• Both Host I/O Cards’ switch 1 settings are in 2 Gb or 1 Gb mode. They must match.

• Host HBA is set to the same speed mode as the Host I/O Cards. It is not recommended to use the auto setting on the HBA. Manually set the speed mode.

Faulty Transceiver. 1) Verify that the transceiver is

functional in the Host I/O card and

the Host HBA (valid Link LED). You

may wish to swap the transceiver

for a “known good” transceiver.

2) Ensure that both the transmit and

receive functions are operational on

both the Host I/O Card and Host

HBA transceivers. The Tx/Rx

signals operate independently. For

example, the transmit on one end is

functioning but the receive function

could be faulty.

Faulty Fibre Channel data

cable.

Replace the Fibre Channel data cable

with a “known good” cable.

Faulty host Fibre Channel

HBA.

Refer to your Fibre Channel host bus

adapter user’s guide for information

on troubleshooting the adapter.

Host HBA failed to boot. Ensure that the Host Fibre Channel

HBA booted and the driver was

properly loaded during the host

system boot process. Refer to your

Fibre Channel HBA user’s guide for

more information.

Common Fibre Loop/Bus Problems



Host I/O Card “H0” or “H1” Link LED is not illuminated. (continued)

Faulty Host I/O Card. Replace the Host I/O Card with a

“known good” card. If a “known

good” card is not available, try

swapping the two Host I/O cards (left

Disk I/O Card “P1” or “P2” Link LED is not illuminated.

Bus speed mode setting not

in agreement.

1) Verify that:

• Both Disk I/O Cards jumpers JP4 are set to 2 Gb or 1 Gb mode. Both cards must match.

• If there is a daisy-chain expansion enclosure, its Disk I/O Cards must match the setting on the primary RAID enclosure cards.

All disk devices must be 2 Gb drives if

the 2 Gb mode is selected. If 1 Gb

mode is selected the disk devices can

be 2 Gb or 1 Gb drives (a 2 Gb drive

will step down to 1 Gb mode).

Faulty Transceiver. 1) Verify that the transceiver are

functional in the Disk I/O card

(valid Link LED). You may wish to

swap the transceiver for a “known

good” transceiver.

2) Ensure that both the transmit and

receive functions are operational on

both the Disk I/O Card transceivers.

The Tx/Rx signals operate

independently. For example, the

transmit on one end is functioning

but the receive function could be

faulty.

For daisy-chain expansion

enclosures, a possible faulty

Fibre Channel data cable.

Replace the Fibre Channel data cable

Problems During Bootup

The following sections describe problems you might encounter during Power On

Self-Test (POST) or during bootup sequence of the enclosure and explains how

to resolve those problems. POST shows problems related to the processor, logic,

and memory.

Nothing is displayed on the terminal emulator screen.

The probable cause of this problem could be an incorrect baud rate setting, a bad RS-232 cable connection or an incorrect cable type.

If the cable is properly connected, ensure that the cable is a null modem type.

Screen is updated, but will not respond to keystrokes.

Improper setting. Disable hardware flow control on the terminal or terminal emulator.

Symptom Solution

Controller failed the onboard memory test (ECC Error).

When this failure occurs, it means the internal CPU memory failed. Replace the controller to correct the problem.

One of the POST diagnostic tests failed.

Replace the faulty controller.

The system hangs during a drive scan.

Follow these steps to resolve the problem:

1 Check the enclosure(s) to make sure everything is properly connected.

2 Remove and replace the drive that failed the scan.

3 If the enclosure(s) and the drive work properly, replace the controller.

An Active-Active controller pair always fails over after booting up.

Verify the same SDRAM DIMM sizes are in both controllers. Active-Active controllers require the same SDRAM DIMM size. Verify that the firmware is the same for both controllers.

Verify that the connector is not physically damaged.

Replacing a Disk Drive

WARNING: Drives and printed circuit board components are sensitive to

electrostatic discharge. To prevent operating failure or damage,

observe the following: Establish a ground for yourself by using the

wrist grounding strap, or by touching the metal chassis prior to

handling or installing the drives or printed circuit board components.

NOTE: There is no need to power off the enclosure or the host computer

system. The drives are hot-swappable. Be careful of the “P-factor” effect

when removing a disk drive, which is the twisting of the drive in your

hand as a result of the spinning disk. Allow the drive to completely spin

down before removing it. Do this by pulling the drive slightly from its

locked position and allowing it to spin down, then remove the drive.

1 Identify the failed disk drive using the Drive Status LED. Refer to

“Troubleshooting” on page 127 and “Drive LEDs” on page 110.

2 Remove the front bezel.

3 Grasp the drive carrier handle and pull the disk drive from the enclosure.
