Every Celerra system consists of three main component elements - the Control Station, the Data Mover and the backend storage.

The Control Station component provides the only administrative interface to the Celerra. From the interface, either graphical or command-line, the Celerra configuration and operations are managed. The Control Station runs an EMC modified version of Red Hat Linux. The Control Station has a “management” network connection to the Data Mover element. On certain NS models it is possible to have a second Control Station for redundancy.

The Data Mover is the component that operates the main “file server” feature of Celerra to provide data access to users. The Data Mover runs an EMC proprietary operating system called DART which stands for Data Access Real Time. Through its fibre channel connection to the backend storage, the Data Mover boots its operating system and accesses user data. For redundancy it is possible to have multiple Data Movers in a Celerra. The number of Data Movers varies based on the specific NS model.

The backend storage provides disk space for the EMC NAS code containing the Data Mover boot code and the Celerra configuration information. User data is also stored one the backend storage disk space. The backend storage for a Celerra must be either a Symmetrix or a CLARiiON. For some NS models it is possible to have multiple backend storage arrays.

NS Integrated FC SystemsOther SAN connected hosts share BEBE available on public network via CS

There are two different types of NS system types - Gateway and Integrated. The differences center around the backend storage and how it is connected to the Celerra and how it is used.

NS Gateway systems do not come with any backend storage but rather connect to an existing backend storage array. The Data Mover fibre channel connectivity to the backend storage is either via a direct connection or a SAN connection. The backend storage does not connect to the Control Station management network, it connects to the site public network and has public network addressing. The backend storage can also be shared with other SAN connected hosts. The backend storage can be either a Symmetrix or a CLARiiON array. And an NS Gateway system can have multiple backend storage arrays.

An NS integrated system includes a backend storage array. The backend storage has been “integrated”with the other Celerra components at the manufacturing facility - having its NAS code installed onto the backend storage. The NS Integrated system Data Movers connect directly to the backend storage. The backend storage is connected to the management network and is assigned management network addressing. On an NS Integrated system the backend storage must be a CLARiiON array and is limited to having just a single backend storage array.

The NS Integrated system has a variation available for certain NS models. The variant is called an NS Integrated FC system, The FC stands for Fibre Channel. The FC variant allows other hosts to connect to the backend storage via SAN connectivity to share the storage with the Celerra. On FC systems the backend storage is accessible on the public network through the Control Station network configuration which will be discussed in more detail later in this course.

Data Movers do not have any local hard drive so they must boot their DART (Data Access Real Time) OS from the backend storage. Although the Control Station manages the Celerra, once a Data Mover is configured it operates independently from the Control Station. A Data Mover can boot and provide data access to clients without the Control Station.

The Celerra Data Mover provides access to data through its network connections to clients within the site production network. Various network protocols are supported for data access. The Celerra stores data on its file systems which are built on disk space from the backend storage.

When a client requests data from the Celerra, it sends an I/O request over the network to the Data Mover. The Data Mover then retrieves the requested data from its file system through fibre channel I/O operations to the backend storage. That data is then transferred back over the network to the client.

Celerra Data Movers can be setup in a Primary to Standby relationship to support continued client data access should a Data Mover failure occur. The relationship is setup as an active/passive configuration where the Primary Data Mover provides access to the data for the clients. The Standby Data Mover remains passive until a Primary Data Mover failure, then it assumes the role of the Primary Data Mover. A Data Mover can be configured to be a Standby Data Mover for multiple Primary Data Movers. The Standby Data Mover must have the same network and fibre channel connectivity as its Primary Data Movers have.

The Data Mover failover operation is managed by the Control Station.

During normal operations the Control Station monitors the status of all the Data Movers via the management network.

If a Primary Data Mover should experience a failure, the Control Station will instruct the Standby Data Mover to take over as Primary while forcing the original Primary, if it is still running, into a failed state.

After the problem is resolved the administrator manually initiates restoration of the original Primary Data Mover to return the system to its normal operations state.

The Control Station boots a modified version of Linux from its local hard drive and runs NAS services to manage and monitor the Celerra system. It accesses NAS information that is stored on the backend storage system.

The Control Station does not have a fibre channel HBA so it cannot access the backend storage directly. It uses an EMC proprietary network protocol called Network Block Storage, similar to iSCSI, over the management network to access a Data Mover. The Data Mover in turn accesses the backend storage via its fibre channel connection to retrieve the data requested by the Control Station.

For the Celerra models with dual Control Station configurations, the two Control Stations are connected together via a dedicated network connection. Both Control Stations run a NAS Master Control Daemon called nasmcd. There are two possible roles for a Control Station - the Primary role and the Standby role. During normal operations on a dual Control Station system, one Control Station will have the Primary role and the other will have the Standby role. The Primary Control Station has access to the NAS information stored on the backend storage. The Standby Control Station monitors the status of the Primary via the dedicated connection and the Master Control Daemon.

If the Primary Control Station fails, the Standby Control Station detects the failure via the NAS Master Control Daemon communication over the dedicated network. The Standby Control Station then assumes the Primary Control Station role and gains access to the NAS information on the backend storage. When the original Primary Control Station becomes available again, it assumes the Standby Control Station role.




Common base with CX series hardware– Same CPU, memory & PCI bus

specifications

Modular I/O components define products– Network personality for NS Data

Mover– Fibre channel personality for CX

Storage Processor– Special personality for some

Integrated model backend storage

Celerra Overview: NS Series Hardware

The Celerra NS series hardware has a common architecture with CLARiiON CX series hardware because they use a common base motherboard. For similar models between the products, for example an NS40 Data Mover and a CX3-40 Storage Processor, each will have the same CPU, memory and PCI bus specifications.

Different modular components are used with the common base to make either product.

A modular network personality component is used to make an NS Data Mover. The component will have various amounts of network ports based on the specific NS model.

A modular fibre channel personality component is used to make a CX Storage Processor. The component will have various amounts of fibre channel ports and may also have iSCSI network ports based on the specific CX model.

For some integrated models a special personality is used to make a Storage Processor for its backend storage. The component will have some different form of fibre channel connectivity than is available from the standard CX models.

The three main Celerra components have connections to the site public network via Ethernet interfaces.

The Control Station has multiple Ethernet interfaces but only one is available for connecting to the public network. It is used for administrative access to the Celerra management interfaces of the Control Station.

The Data Mover has multiple Ethernet interface connections available for clients to access the data stored on the Celerra. The number and type of connections will vary based on the specific NS model. Generally there are interfaces available for both copper or optical based media.

If the NS model is a Gateway system with a CLARiiON backend storage system, both SPs will have a Ethernet interface that connects to the public network for administrative access to the array management interface.

On the 3rd generation of NS systems there are two independent management networks. The blades and the enclosure incorporate two management switches for connecting to the two networks. The two management networks have the following default network addresses:

128.221.253.0

128.221.252.0

The management network must never be connected to the public network, it is designed to operate as a private network only.

The Control Station has two Ethernet interfaces that connect to the two networks. Through these redundant management networks the Control Station monitors and manages the Celerra.

The Blades and the enclosure are connected to the two networks by the management switches. Through the enclosure mid-plane connections both management switches and blades are connected together so that the blades connect to both networks. Through the connections on the management switches it is possible to connect to additional enclosures by daisy-chaining them together.

On integrated models the management network connects to the CLARiiON backend storage for array monitoring and management. Each SP has a single connection and thus only connects to one of the management networks.

Data Mover

On the 1st and 2nd generations of NS systems there is only one physical Ethernet network that forms the management network. A single Ethernet switch that is part of the Control Station assembly provides a connection point for all the connected components. The network is augmented with a serial connection from the Control Station and the Data Movers. The one physical network is configured with sub interfaces to have the following default network addresses:

128.221.253.0

128.221.252.0

The management network must never be connected to the public network, it is designed to operate as a private network only.

The Control Station has only one Ethernet interface that connects into the Ethernet Switch. The Control Station has additional connectivity for up to four Data Movers via serial connections to provide limited functions if the physical network fails. Through these two connections the Control Station monitors and manages the Celerra.

The Data Movers have a single Ethernet interface for connecting to the Ethernet switch. There is also a single serial connection to the Control Station.

On integrated models the CLARiiON backend storage also connects to the management network for array monitoring and management. Each SP has a single connection to the Ethernet switch.

The connectivity for dual Control Station systems is somewhat different for the different generations of NS systems. The Control Stations connect together using their IPMI (Intelligent Platform Management Interface) Ethernet interface. This allows the Control Stations to communicate together via the NAS Master Control Daemon (nasmcd).

Dual Control Stations on a 3rd generation NS system have both Control Stations connected together via their IPMI Ethernet interfaces. Additionally the Standby Control Station is connected into the two management networks by connecting its two management Ethernet interfaces to the management switches of the blade enclosure.

Dual Control Stations on the earlier generation NS systems also have both Control Stations connected together via their IPMI Ethernet interfaces. The Standby Control Station management Ethernet interface is connected to its Ethernet switch. A second Ethernet interface on the Standby Control Station connects to the Primary Control Station Ethernet switch. An Ethernet interface from the Primary Control Station is connected to the Standby Control Station Ethernet switch. The Standby Control Station is serially connected to a second serial port on the Data Mover. Finally a second management Ethernet interface on the Data Mover is connected to the Standby Control Station Ethernet switch.

The Celerra NS20 and NS40 system lines are shown here. The two different system lines share some similar characteristics. The NS20 and the NS40 are both available in Integrated and Integrated FC models. NS20 and NS40 systems are available in single or dual blade configurations. Both system types are available in factory racked EMC cabinets or can be field installed into site cabinets. The components have the same 1U physical size.

The systems also have some notable differences. The NS20 is only available as an Integrated model while the NS40 is available as an Integrated or Gateway. Another notable difference is that the NS40 comes in a DC power variant for TELCO environments. The systems conform to the Network Equipment-Building System (NEBS) standards. The NS40 NEBS Integrated and the NS40 NEBS Gateway systems are not available in EMC cabinets, they are field installed into site cabinets.

To understand the various NS40 and NS20 system types it helps to understand a timeline of when the products were introduced.

The NS40 Integrated and Gateway systems with the NEBS variants were developed and introduced first and are supported beginning with the 5.5 family of EMC NAS code.

The NS20 Integrated and Integrated FC models were introduced in August 2007 and were focused on ease of installation and use. The same ease of use effort was applied to the NS40 system and thus new NS40 Integrated and Integrated FC systems were introduced. The newly introduced NS40 Integrated varies form the original model – the difference is with the type of backend storage delivered with the system and the fibre channel connections it has for the NS40 blades.

SPs public addresses for NST & SAN Hosts

NS20 systems and new NS40 systems, both Integrated and the Fibre Channel option, have their backend Storage Processors configured with site public addresses. This is to allow the backend storage to be accessed with the Navisphere Service Taskbar utility for service operations and to allow CLARiiON management for SAN connected hosts on the NS20 and NS40 FC models. To enable communications from the site public network to the Storage Processors which are physically connected to the Celerra Management networks, the Control Station is configured to bridge the communications form the public network to the management network by using proxy arp.

When a request is made to the site public address of the SP, the Control Station Ethernet interface eth3 answers the arp request in proxy for the SP. The data is then sent to eth3 of the Control Station and then passes it to the appropriate management network for the requested Storage Processor.

List the storage capacities for the Celerra Platforms





Based on Celerra models– Hardware capabilities– Number of disks

Based on EMC NAS code– Efficiencies for storage objects– CLARiiON FLARE code– Symmetrix microcode– Newer code supports higher capacity drives


The Storage capacity of a Celerra is based upon the hardware model and EMC NAS code version running on the system.

The different models will have various hardware capabilities that affect the storage capacities. Some models are limited in the number of disk drives contained in the system and thus affect the storage capacity.

The version of EMC NAS code also affects the storage capacity of a system. Newer EMC NAS codes realize efficiencies for handling the storage related objects thus capacities can increase. Newer EMC NAS codes also support newer backend storage code which in turn support larger disk capacities.
