Chapter 1: Introduction

This guide documents the Broadcom® family of MegaRAID® cache backup products used with MegaRAID SAS 8xxx and SAS 92xx high-performance SAS+SATA RAID controllers to protect cached data. Refer to MegaRAID CacheVault Protection Products User Guide for details on additional Broadcom backup products. This guide describes the backup products, including installation instructions and technical specifications.

This guide documents the following cache backup products:

Intelligent battery backup units (iBBUs)

Intelligent transportable battery backup units (iTBBUs)

Transportable memory modules (TMMs)

RAID cache module (RCM01)

CacheVault® flash modules (CVFMs)

CacheVault power modules (CVPMs)

1.1 Overview

The battery backup units and the memory modules protect the integrity of cached data on MegaRAID controllers by providing backup power if a complete AC power failure or a brief power outage occurs. These products provide an alternative to using an uninterruptible power supply (UPS), or a second level of fault tolerance when used with a UPS.

1.1.1 Cache Backup Benefits

The cache memory available on MegaRAID controllers improves overall system performance because writing data to the controller's cache memory is much faster than writing it to a storage device. Write operations appear to complete quickly at the software application level. The MegaRAID controller writes the cached data to the storage device when system activity is low or when the cache gets full.

The risk of using write-back cache is that the cached data can be lost if the AC power fails before the data is written to the storage device. To eliminate this risk, the MegaRAID controller supports an energy backup solution to ensure no data is lost during power or system failure. Depending on the MegaRAID controller, the data is held resident in the cache memory or offloaded to flash, which is restored when power resumes.

1.1.2 Battery Backup Units

An intelligent BBU (iBBU) has built-in functionality to charge the battery pack automatically and to communicate battery status information such as, voltage, temperature, and current, to the host computer system.

An intelligent transportable BBU (iTBBU) combines a battery and memory, and moves cached data from a failed controller to a replacement controller. This action could be necessary if, for example, the controller fails after an unexpected power failure. After you install the iTBBU on a new controller of the same type as the failed controller, it flushes the unwritten data preserved in the cache to the drive through the new controller. For more information, see Section 3.4, Transfer Cached Data from a Failed Controller.

The MegaRAID iBBUs monitor the voltage level of the DRAM modules on MegaRAID controllers. If the voltage drops below a predefined level, the battery backup unit switches the memory power source from the MegaRAID controller to the battery pack attached to the iBBU. As long as the voltage level stays below the predefined value, the MegaRAID iBBU provides power for memory. If the voltage level returns to an acceptable level, the iBBU switches the power source back to the MegaRAID controller, and all pending writes to storage devices complete with no data loss.



The only functional difference between an iBBU and an iTBBU is that the iTBBU mounts on the DIMM itself and can be transferred onto a new MegaRAID card without compromising cache integrity.

1.1.3 CacheVault Modules

CacheVault technology consist of two primary items. The CacheVault power module (CVPM) is an ultracapacitor based energy source that powers the critical adapter components in the event of a power loss, long enough to offload cached data to the nonvolatile flash memory on the CacheVault flash module (CVFM). The DRAM contents are restored to the CVFM the next time the MegaRAID controller is powered and the cached data is written to the storage devices. The CVPM is also sometimes referred to as a supercapacitor or flash backup unit (FBU).

CacheVault flash technology virtually eliminates the hardware maintenance associated with batteries, offers lower total cost of ownership over the life of the controller, and provides more environmentally friendly cache protection, all while maintaining optimal RAID performance.

The CVPM provides sufficient energy for the cache memory contents to transfer from DRAM to a nonvolatile flash memory array on the CVFM or to NAND flash memory down on the MegaRAID controller.

CAUTION! You cannot hot-plug a CVPM. Removing or inserting a CVPM with the server powered on damages the board and the supercapacitor functionality. To attach a CVPM to, or remove a CVPM from, a controller, you must fully power down the controller before you attach the module to, or remove the module from, its mating connector.

Chapter 2: Install the Cache Backup Products

This chapter explains how to install the BBUs used on MegaRAID controllers and how to connect the CacheVault module to back up power units.

CAUTION! Electrostatic discharge (ESD) can damage the BBUs and the MegaRAID controllers on which they are installed. Always ground yourself, and use a ground strap before you touch the MegaRAID controller or the BBU. Perform all installation work at an ESD-safe workstation that meets the requirements of EIA-625, Requirements for Handling Electrostatic Discharge Sensitive Devices. Follow the ESD-recommended practices in the latest revision of the Inter-Process Communication (IPC) IPC-A-610, Acceptability of Electronic Assemblies, standard.

If screws are required to attach the iBBU to the MegaRAID controller, use an ESD-safe Phillips screwdriver to install them. Be sure the screwdriver is centered in the screw to avoid damaging the screw head. If you exceed the maximum torque specification, you might damage the board, connectors, or screws, and you void the warranty of the board.

The batteries in the iBBUs must recharge for at least six hours to charge under normal operating conditions.

NOTE: To protect your data, set the MegaRAID controller Write Policy to write-through until the battery unit is charged. After the battery unit charges, you can change the Write Policy to write-back to take advantage of data caching performance improvements.

The maximum operating temperature (ambient) for the battery packs is 40°C. See Chapter 3, Monitor and Manage BBUs and CacheVault Modules, for iBBU technical specifications.

The temperature of the battery packs is generally 15°C to 20°C higher than the ambient temperature during charging. Therefore, to complete the charge cycle, ambient temperature should be less than 40°C. If the ambient temperature exceeds 40°C, the charge cycle terminates prematurely, which prevents the battery pack from reaching a fully charged state.

Chapter 3: Monitor and Manage BBUs and CacheVault Modules

This chapter explains how to monitor and manage the MegaRAID BBUs and the CacheVault modules used with the MegaRAID SAS controllers. Most MegaRAID BBU functions, such as battery recharging, occur automatically.

You can use the following MegaRAID utility programs to monitor and manage the battery status (temperature, voltage, and so on):

MegaRAID WebBIOS configuration utility

Ctrl-R utility

MegaCLI utility

Storage Command Line Tool (StorCLI)

MegaRAID Storage Manager configuration utility

Human Interface Infrastructure (HII) configuration utility

NOTE: For more information about BBU and CacheVault functions in these utilities, refer to the MegaRAID SAS Software User Guide, which applies to 6Gb/s MegaRAID controllers, or the 12Gb/s MegaRAID SAS Software User Guide for 12Gb/s MegaRAID controllers.

You can use the following MegaRAID utility programs to retrieve status information for CVPMs used with MegaRAID controllers:

HII configuration utility

StorCLI utility

3.1 Monitor and Manage BBUs with MegaRAID Configuration Utilities

This section describes how to use the MegaRAID utilities to monitor the condition of installed BBUs and perform management operations. Review the section for your implemented configuration utility:

MegaRAID WebBIOS: Section 3.1.1, Monitor and Manage BBUs with the WebBIOS Configuration Utility

Ctrl-R: Section 3.1.2, Monitor and Manage BBUs with the Ctrl-R Utility

MegaCLI: Section 3.1.3, Monitor and Manage BBUs with the MegaCLI Configuration Utility

StorCLI: Section 3.1.4, Monitor and Manage BBUs with the StorCLI Configuration Utility

MegaRAID Storage Manager: Section 3.1.5, Monitor and Manage BBUs with the MegaRAID Storage Manager Configuration Utility

HII: Section 3.1.6, Monitor and Manage BBUs with the HII Configuration Utility

3.1.1 Monitor and Manage BBUs with the WebBIOS Configuration Utility

The MegaRAID WebBIOS configuration utility (CU) configures disk groups and logical drives. Because the WebBIOS CU resides in the BIOS, it is independent of the operating system. The following subsections document how to monitor and manage the BBUs using the WebBIOS CU.

3.1.1.1 View BBU Information

If your MegaRAID controller has a BBU, use the following steps to view information about the unit.

1. Click Controller Properties on the main WebBIOS CU screen.

The first Controller Information screen appears, as shown in the following figure.



Figure 46 First Controller Information Screen

The information on this screen is read-only and cannot be modified directly. The screen shows the number of virtual drives already defined on this controller, and the number of drives connected to the controller.

2. Click Next to view the second Controller Information screen.

The second Controller Properties screen appears, as shown in the following figure. The Battery Backup field indicates whether the BBU is present, and provides access to the Battery Module screen.

Figure 47 Second Controller Properties Screen

3. Does the Battery Backup field show None or Present?

None. No battery backup is detected.

Present. Click Present in the Battery Backup field.

The Battery Module screen appears, as shown in the following figure. This screen contains the following information:

Battery information

Design information

Capacity information

Auto Learn properties and settings



Figure 48 Battery Module Screen

Most Battery Module properties are view only.

The Auto Learn options are at the lower-right corner of the screen. A learning cycle is a battery calibration operation performed by the controller periodically to determine the condition of the battery. If necessary, you can change the learn delay interval (the length of time between automatic learning cycles) and the Auto Learn mode.

NOTE: To increase the life of a battery, the battery is not fully charged. Band gap charging keeps the maximum battery charge within a band comfortably above the time requirement instead of keeping the battery charged to the maximum level. However, when a learn cycle is required, the battery is fully charged because a learn cycle starts only after the battery is fully charged.

3.1.1.2 Set the Learn Delay Interval

The learn delay interval is the length of time between automatic learning cycles. Perform the following steps to change the interval:

1. Open the drop-down menu in the Auto Learn Mode field.

2. Select the learn mode as Auto (the default) so the controller performs the learning cycle automatically.

3. Change the number of hours in the Learn Delay Interval field.

You can delay the start of the learn cycles for up to 168 hours (7 days).

4. Click Go to set the interval.



3.1.1.3 Set the Auto Learn Mode

You can start battery learning cycles manually or automatically. The Auto Learn modes include the following modes:

BBU Auto Learn

The firmware tracks the time since the last learning cycle and performs a learn cycle when due.

BBU Auto Learn Disabled

The firmware does not monitor or initiate a learning cycle. You manually schedule learning cycles.

BBU Auto Learn Warn

The firmware warns about a pending learning cycle. You initiate a learning cycle manually. After the learning cycle is complete, the firmware resets the counter and warns you when the next learning cycle time is reached.

1. Open the drop-down menu in the Auto Learn Mode field.

2. Select an Auto Learn mode.

3. Click Go to set the Auto Learn mode.

NOTE: When you replace the iBBU, the charge cycle counter resets automatically.

3.1.2 Monitor and Manage BBUs with the Ctrl-R Utility

The Ctrl-R Utility is a BIOS configuration utility that lets you create and manage RAID configurations on Broadcom MegaRAID controllers. You can configure the drive groups and drives on the system before the operating system is installed.

If your MegaRAID controller has a BBU, you can view BBU information and change some settings. A learning cycle is a battery calibration operation that the controller performs periodically to determine the condition of the battery.

Perform the following steps to view and change the battery settings.

1. Navigate to the second Controller Settings screen and select Manage Battery.

The Battery Properties dialog appears. You can view the battery type, battery state, temperature, capacity information, estimated backup time, and learn mode information. Most battery properties are read only.



Figure 49 Battery Properties Dialog

If the Battery State field has a value other than Optimal, the Non-Optimal Reason field appears at the bottom of the Battery Properties dialog. The Non-Optimal Reason field is a read-only field and states a reason for the non-optimal state of the battery.

2. Select a battery learn mode from the Learn Mode drop-down list. If the battery supports transparent learn cycles, see Step a. If the battery does not support transparent learn cycles, see Step b. The drop-down values differ based on whether the battery supports transparent learn cycles.

a. The following values appear in the Learn Mode drop-down list:

Transparent. The firmware tracks the time since the last learning cycle and performs a learn cycle when it is due.

Disabled. The firmware does not monitor or initiate a learning cycle. Schedule learning cycles manually.

Unknown. The firmware warns about a pending learning cycle. You can start a learning cycle manually. After the learning cycle completes, the firmware resets the counter and warns you when the next learning cycle time is reached.

b. The following values appear in the Learn Mode drop-down list:

Automatic. The firmware tracks the time since the last learning cycle and performs a learn cycle when due. Write caching need not be disabled.

Disabled. The firmware does not monitor or initiate a learning cycle. Schedule learning cycles manually.

Disabled (Warning Only). The firmware never initiates a battery learn cycle but notifies you through events when a learn cycle is needed.

3. Press OK to change the learn mode.

3.1.3 Monitor and Manage BBUs with the MegaCLI Configuration Utility

The MegaCLI utility is a character-based, non-GUI, command line utility that you can use to configure, monitor, and maintain MegaRAID controllers and the devices connected to them. The MegaCLI utility runs on the Red Hat Linux and Microsoft Windows operating systems.

3.2 Replace Battery Backup Units

You should replace the BBU every year or after 500 learn cycles, or as indicated by MegaRAID management tools when the battery status indicates replacement is required. The warranty on battery packs is one year.

After you install a new BBU, use one of the MegaRAID configuration utilities to perform a learn cycle to make sure the new BBU functions properly. For instructions, see Section 3.1, Monitor and Manage BBUs with MegaRAID Configuration Utilities.

3.3 Dispose of Battery Backup Units

WARNING! Do not damage the battery pack in any way. Toxic chemicals can be released if it is damaged.

The material in the battery pack contains heavy metals that can contaminate the environment. Federal, state, and local regulations prohibit the disposal of rechargeable batteries in public landfills. Be sure to recycle the old battery packs properly. Broadcom reminds you that you must comply with all applicable battery disposal and hazardous material handling laws and regulations in the country or other jurisdiction where you are using the BBU.

3.4 Transfer Cached Data from a Failed Controller

If you are using a MegaRAID controller with an LSIliTBBU03 unit and the MegaRAID controller fails when there is data in the cache that has not been written to disk, you can save the data. To do so, remove the BBU from the failed MegaRAID controller and install it on a new MegaRAID controller. For the data to be saved, the following conditions must be met:

The new MegaRAID controller on which you install the BBU must be the same model as the failed MegaRAID controller.

The replacement MegaRAID controller must have a cleared configuration.

The new MegaRAID controller must connect to the same disk drives as the original configuration.

Follow these steps to use the transportable BBU to transfer cached data from a failed controller to a new controller:

1. Ground yourself before touching the MegaRAID controller or the transportable BBU.

2. Turn off the power to the computer system and disk drives.

3. Remove the failed MegaRAID controller from the system.

4. Remove the transportable BBU from the failed MegaRAID controller.

5. Install the transportable BBU on the replacement RAID controller.

6. Install the replacement MegaRAID controller in the computer and connect it to the disk drives.


The replacement MegaRAID controller reads the disk configuration into NVRAM and flushes the cache data to the virtual drives.

3.5 Monitor CacheVault Module Information

You can view information about the CVPMs by using the following Broadcom software utilities:

HII Configuration utility

StorCLI

3.5.1 Monitor CacheVault Module Information with the HII Configuration Utility

You can use the HII Configuration utility to display information about the CVPM on the following Battery Management screen. <SuperCaP> in the Type field refers to the CVPM.



Figure 54 HII Battery Management Screen

3.5.2 Monitor CacheVault Module Information in StorCLI

The StorCLI utility supports the following CacheVault command, which identifies the specific controller to which a CacheVault module is connected:storcli /cx/cv show all

The object identifier /cx/cv refers to the CacheVault module on controller x. Only one CacheVault module can connect to a controller at a time.

NOTE: This command works only when a CacheVault module is connected to the controller; otherwise, an error message appears.

Input example: storcli /c0/cv show all

where, c0 identifies controller number 0.

3.6 Handle and Dispose of CacheVault Power Modules

The CVPM01 module is a power module that contains individual supercapacitors, which are low-voltage devices, but can deliver extremely high currents especially in short-circuit situations. Handle the supercapacitors in an uncharged state.

The following statements are general safety considerations.

Supercapacitors can vent or rupture if overcharged, reverse charged, incinerated, or heated above 150°C.

Do not crush, mutilate, nail penetrate, or disassemble.

High case temperature (burn hazard) can result from abuse of the supercapacitor.

In the event the packaging of an individual capacitor is compromised, either by puncturing or crushing, a very limited amount of electrolyte fluid will be released. If the product is found to be leaking (identified by a white salt crystal formation on product), remove it from the system. A leaking capacitor will eventually increase in resistance or could cause long-term corrosion of interconnects. Incidental contact with the white salt residue is not harmful, although it should not be ingested. Take normal precautions after contact, which includes washing hands.



Supercapacitors are composed of aluminum, carbon, paper, and an organic electrolyte. Supercapacitors contain no heavy metals or toxic materials hazardous to the environment. Municipalities differ in how materials are classified for disposal. A material safety data sheet (MSDS) for the electrolyte (acetonitrile) is available to aid in determining regional or local classification and disposal requirements.

4.2 CacheVault Module Specifications

The following table lists the specifications for the CVFM and CVPM.

4.3 Battery Life and Data Retention Time

The MegaRAID utilities display a counter showing the number of times a BBU has been recharged. When you replace a BBU, run the utility program and reset this counter to zero for the new BBU.

You should replace the battery pack on the BBU once a year or after 500 recharging cycles, whichever comes first. The warranty on the battery packs is good for one year. The warranty on the CacheVault modules is three years.

The data retention times shown in the following table are approximate and can vary based on a number of factors, including the following factors:

Capacity of the battery pack and the battery load

Ambient temperature

Memory bus width Maximum 72-bit LSIiBBU06: 40-bit

LSIiBBU07 and LSIiTBBU03: 72-bit

Error correcting capability (ECC) N/A N/A, except for LSIiTBBU03, which supports this feature.

a. These battery products can detect the presence of an external auxiliary power source. Circuitry on this product automatically chooses auxiliary power to maintain cache contents, deferring battery discharge until auxiliary power is removed or exhausted. Presence of an auxiliary power source thus increases the overall DRT ratings in Table 8, Reference Data Retention Times.

Appendix A: Battery Glossary

Absolute state of charge

Predicted remaining battery capacity expressed as a percentage of Design Capacity. The Absolute State of Charge operation can return values greater than 100%.

Auto learn mode

The controller performs the learn cycle automatically in this mode. This mode offers the following options:

– BBU Auto Learn: The firmware tracks the time since the last learn cycle and performs a learn cycle when due.

– BBU Auto Learn Disabled: The firmware does not monitor or initiate a learn cycle. You can schedule learn cycles manually.

– BBU Auto Learn Warn: The firmware warns about a pending learn cycle. You can initiate a learn cycle manually. After the learn cycle is complete, the firmware resets the counter and warns you when the next learn cycle time is reached.

Auto learn period

Time between learn cycles. A learn cycle is a battery calibration operation performed periodically by the controller to determine the condition of the battery.

Average time to empty

One-minute rolling average of the predicted remaining battery life.

Average time to full

Predicted time to charge the battery to a fully charged state based on the one minute rolling average of the charge current.
