xxiv SAN Volume Controller: Model 2145-CG8 Hardware Installation Guide

Attention: Static electricity can damage electronic devices and your system. Toavoid damage, keep static-sensitive devices in their static-protective bags until youare ready to install them.

To reduce the possibility of electrostatic discharge, observe the followingprecautions:v Limit your movement. Movement can cause static electricity to build up around

you.v Handle the device carefully, holding it by its edges or frame.v Do not touch solder joints, pins, or exposed printed circuitry.v Do not leave the device where others can handle and possibly damage the

device.v While the device is still in its antistatic bag, touch it to an unpainted metal part

of the system unit for at least two seconds. (This action removes static electricityfrom the package and from your body.)

v Remove the device from its package and install it directly into your SANVolume Controller, without putting it down. If it is necessary to put the devicedown, place it onto its static-protective bag. (If your device is an adapter, place itcomponent-side up.) Do not place the device onto the cover of the SAN VolumeController or onto a metal table.

v Take additional care when you handle devices during cold weather becauseheating reduces indoor humidity and increases static electricity.

Chapter 1. SAN Volume Controller overview

The SAN Volume Controller combines software and hardware into acomprehensive, modular appliance that uses symmetric virtualization.

Symmetric virtualization is achieved by creating a pool of managed disks (MDisks)from the attached storage systems. Those storage systems are then mapped to a setof volumes for use by attached host systems. System administrators can view andaccess a common pool of storage on the storage area network (SAN). Thisfunctionality helps administrators to use storage resources more efficiently andprovides a common base for advanced functions.

Each SAN Volume Controller node is an individual server in a SAN VolumeController clustered system on which the SAN Volume Controller software runs.

The nodes are always installed in pairs, with a minimum of one and a maximumof four pairs of nodes constituting a system. Each pair of nodes is known as an I/Ogroup. All I/O operations that are managed by the nodes in an I/O group arecached on both nodes.

SAN Volume Controller operating environmentTo use the system, you must meet the minimum hardware and softwarerequirements and ensure that other operating environment criteria are met.

Minimum requirements

You must set up your SAN Volume Controller operating environment according tothe following requirements:v Minimum of one pair of SAN Volume Controller nodesv Minimum of two uninterruptible power supply unitsv One optional IBM System Storage Productivity Center per SAN installation for

configuration

Note: The optional SSDs and optional 10 Gbps Ethernet cannot be in the samenode.

Redundant ac-power switchThe redundant ac-power switch is an optional feature that makes the SAN VolumeController nodes resilient to the failure of a single power circuit. The redundantac-power switch is not a replacement for an uninterruptible power supply. Youmust still use a uninterruptible power supply for each node.

You must connect the redundant ac-power switch to two independent powercircuits. One power circuit connects to the main power input port and the otherpower circuit connects to the backup power-input port. If the main power to theSAN Volume Controller node fails for any reason, the redundant ac-power switchautomatically uses the backup power source. When power is restored, theredundant ac-power switch automatically changes back to using the main powersource.

Place the redundant ac-power switch in the same rack as the SAN VolumeController node. The redundant ac-power switch logically sits between the rackpower distribution unit and the 2145 UPS-1U.

You can use a single redundant ac-power switch to power one or two SAN VolumeController nodes. If you use the redundant ac-power switch to power two nodes,the nodes must be in different I/O groups. In the event that the redundantac-power switch fails or requires maintenance, both nodes turn off. Because thenodes are in two different I/O groups, the hosts do not lose access to the back-enddisk data.

For maximum resilience to failure, use one redundant ac-power switch to powereach SAN Volume Controller node.

Figure 1 shows a redundant ac-power switch.

You must properly cable the redundant ac-power switch units in yourenvironment. Refer to the Planning section in the Information Center for moreinformation.

Uninterruptible power supplyThe uninterruptible power supply protects a SAN Volume Controller node againstblackouts, brownouts, and power surges. The uninterruptible power supplycontains a power sensor to monitor the supply and a battery to provide poweruntil an orderly shutdown of the system can be performed.

SAN Volume Controller 2145-CG8 uses the 2145 UPS-1U.

2145 UPS-1UA 2145 UPS-1U is used exclusively to maintain data that is held in the SANVolume Controller dynamic random access memory (DRAM) in the event of anunexpected loss of external power. This use differs from the traditionaluninterruptible power supply that enables continued operation of the device that itsupplies when power is lost.

With a 2145 UPS-1U, data is saved to the internal disk of the SAN VolumeController node. The uninterruptible power supply units are required to power theSAN Volume Controller nodes even when the input power source is considereduninterruptible.

Note: The uninterruptible power supply maintains continuous SAN VolumeController-specific communications with its attached SAN Volume Controllernodes. A SAN Volume Controller node cannot operate without the uninterruptiblepower supply. The uninterruptible power supply must be used in accordance withdocumented guidelines and procedures and must not power any equipment otherthan a SAN Volume Controller node.

2145 UPS-1U configurationA 2145 UPS-1U powers one SAN Volume Controller node.

To make the SAN Volume Controller clustered system more resilient against powerfailure, the 2145 UPS-1U units can be connected to the redundant ac-power switch.

If a redundant ac-power switch is not used, the two uninterruptible powersupplies that power an I/O group can be connected to different, independentelectrical power sources. In this case, if a single power source fails, only one nodein the I/O group stops and the SAN Volume Controller system can continue tooperate, although with reduced performance.

Each uninterruptible power supply must be in the same rack as the node that itpowers.

Each 2145 UPS-1U includes one power cord that connects the uninterruptiblepower supply to a redundant ac-power switch, if one exists, or to a rack powerdistribution unit (PDU), if one exists. The 2145 UPS-1U also includes an alternativepower cable to connect to an external power source that is specific to yourgeography.

Each 2145 UPS-1U is connected to a SAN Volume Controller node with a powercable and a signal cable. To avoid the possibility of power and signal cables beingconnected to different uninterruptible power supplies, these cables are wrappedtogether and supplied as a single field-replaceable unit (FRU). The SAN VolumeController node reads status and identification information from theuninterruptible power supply using the signal cable.

Chapter 1. SAN Volume Controller overview 3

Overview of Rack Cabinet Physical Location PlanningThis topic gives an overview of considerations regarding the physical location ofSAN Volume Controller components in the rack cabinet.

Refer to the planning section of the IC for full details of how to locate the SANVolume Controller components in a rack cabinet.

Key points to consider:v Plan for:

– Any optional redundant ac-power switches to be together at the bottom of therack cabinet

– For the 2145 UPS-1Us to be together, keep them as low as possible in the rackcabinet and ensure it is stable.

– For the 2145 CG8 nodes to be together, above the other SAN VolumeController components.

v Do not sandwich less deep units between deeper ones.v Allow spare rack unit space for cable runs and service access.v Power the nodes in an I/O Group from different power sources. If using

redundant ac-power switches alternate the master and backup power sources.
