Installation and configuration overview xxvii
xxviii SAN Volume Controller: Model 2145-CG8 Hardware Installation Guide
Chapter 1. SAN Volume Controller overview
The SAN Volume Controller combines software and hardware into a
comprehensive, 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 set
of volumes for use by attached host systems. System administrators can view and
access a common pool of storage on the storage area network (SAN). This
functionality helps administrators to use storage resources more efficiently and
provides a common base for advanced functions.
Each SAN Volume Controller node is an individual server in a SAN Volume
Controller clustered system on which the SAN Volume Controller software runs.
The nodes are always installed in pairs, with a minimum of one and a maximum
of four pairs of nodes constituting a system. Each pair of nodes is known as an I/O
group. All I/O operations that are managed by the nodes in an I/O group are
cached on both nodes.
SAN Volume Controller operating environment
To use SAN Volume Controller, you must meet the minimum hardware and
software requirements and ensure that other operating environment criteria are
met.
Minimum requirements
You must set up your SAN Volume Controller operating environment according to
the following requirements:
v Minimum of one pair of SAN Volume Controller nodes
v Minimum of two uninterruptible power supply units
v One optional IBM System Storage Productivity Center per SAN installation for
configuration
SAN Volume Controller 2145-CG8 node features
The SAN Volume Controller 2145-CG8 node has the following features:
v A 19-inch rack-mounted enclosure
v One 4-port 8 Gbps Fibre Channel adapter
3
3
v One 2-port 10 Gbps Fibre Channel over Ethernet converged network adapter
v 24 GB memory
v Fibre Channel over Ethernet host attachment (need to add only one)
v One quad-core processor
v Dual, redundant power supplies
v Supports up to four optional solid-state drives (SSDs)
v iSCSI host attachment (1 Gbps Ethernet and optional 10 Gbps Ethernet)
v Supports optional IBM Real-time Compression
© Copyright IBM Corp. 2012 1
Note: The optional SSDs and optional 10 Gbps Ethernet cannot be in the same
node.
Redundant ac-power switch
The redundant ac-power switch is an optional feature that makes the SAN Volume
Controller nodes resilient to the failure of a single power circuit. The redundant
ac-power switch is not a replacement for an uninterruptible power supply. You
must still use a uninterruptible power supply for each node.
You must connect the redundant ac-power switch to two independent power
circuits. One power circuit connects to the main power input port and the other
power circuit connects to the backup power-input port. If the main power to the
SAN Volume Controller node fails for any reason, the redundant ac-power switch
automatically uses the backup power source. When power is restored, the
redundant ac-power switch automatically changes back to using the main power
source.
Place the redundant ac-power switch in the same rack as the SAN Volume
Controller node. The redundant ac-power switch logically sits between the rack
power distribution unit and the 2145 UPS-1U.
You can use a single redundant ac-power switch to power one or two SAN Volume
Controller 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 redundant
ac-power switch fails or requires maintenance, both nodes turn off. Because the
nodes are in two different I/O groups, the hosts do not lose access to the back-end
disk data.
For maximum resilience to failure, use one redundant ac-power switch to power
each SAN Volume Controller node.
Figure 1 shows a redundant ac-power switch.
svc00297
Figure 1. Photo of the redundant ac-power switch
Cabling of redundant ac-power switch (example)
You must properly cable the redundant ac-power switch units in your
environment.
Note: While this topic provides an example of the cable connections, it does not
indicate a preferred physical location for the components.
2 SAN Volume Controller: Model 2145-CG8 Hardware Installation Guide
Figure 2 shows an example of the main wiring for a SAN Volume Controller
clustered system with the redundant ac-power switch feature. The four-node
clustered system consists of two I/O groups:

13 Site PDU X (C13 outlets)
14 Site PDU Y (C13 outlets)
The site PDUs X and Y (13 and 14) are powered from two independent power
sources.
In this example, only two redundant ac-power switch units are used, and each
power switch powers one node in each I/O group. However, for maximum
redundancy, use one redundant ac-power switch to power each node in the
system.
Some SAN Volume Controller node types have two power supply units. Both
power supplies must be connected to the same 2145 UPS-1U, as shown by node A
and node B. The SAN Volume Controller 2145-CG8 is an example of a node that
has two power supplies. The SAN Volume Controller 2145-8A4 is an example of a
node that has a single power supply.
Uninterruptible power supply
The uninterruptible power supply protects a SAN Volume Controller node against
blackouts, brownouts, and power surges. The uninterruptible power supply
contains a power sensor to monitor the supply and a battery to provide power
until an orderly shutdown of the system can be performed.
SAN Volume Controller 2145-CG8 uses the 2145 UPS-1U.
2145 UPS-1U
A 2145 UPS-1U is used exclusively to maintain data that is held in the SAN
Volume Controller dynamic random access memory (DRAM) in the event of an
unexpected loss of external power. This use differs from the traditional
uninterruptible power supply that enables continued operation of the device that it
supplies when power is lost.
With a 2145 UPS-1U, data is saved to the internal disk of the SAN Volume
Controller node. The uninterruptible power supply units are required to power the
SAN Volume Controller nodes even when the input power source is considered
uninterruptible.
Note: The uninterruptible power supply maintains continuous SAN Volume
Controller-specific communications with its attached SAN Volume Controller
nodes. A SAN Volume Controller node cannot operate without the uninterruptible
power supply. The uninterruptible power supply must be used in accordance with
documented guidelines and procedures and must not power any equipment other
than a SAN Volume Controller node.
2145 UPS-1U configuration
A 2145 UPS-1U powers one SAN Volume Controller node.
To make the SAN Volume Controller clustered system more resilient against power
failure, the 2145 UPS-1U units can be connected to the redundant ac-power switch.
4 SAN Volume Controller: Model 2145-CG8 Hardware Installation Guide
If a redundant ac-power switch is not used, the two uninterruptible power
supplies that power an I/O group can be connected to different, independent
electrical power sources. In this case, if a single power source fails, only one node
in the I/O group stops and the SAN Volume Controller system can continue to
operate, although with reduced performance.
Each uninterruptible power supply must be in the same rack as the node that it
powers.
Each 2145 UPS-1U includes one power cord that connects the uninterruptible
power supply to a redundant ac-power switch, if one exists, or to a rack power
distribution unit (PDU), if one exists. The 2145 UPS-1U also includes an alternative
power cable to connect to an external power source that is specific to your
geography.
Each 2145 UPS-1U is connected to a SAN Volume Controller node with a power
cable and a signal cable. To avoid the possibility of power and signal cables being
connected to different uninterruptible power supplies, these cables are wrapped
together and supplied as a single field-replaceable unit (FRU). The SAN Volume
Controller node reads status and identification information from the
uninterruptible power supply using the signal cable.

Chapter 2. Installing the SAN Volume Controller 2145-CG8 hardware 15
4. Verify that the redundant ac-power switch power cables are tidy. Ensure that
they do not obstruct other equipment and that they are tied in place where
necessary.
Testing the redundant ac-power switch
You can test the redundant ac-power switch before you continue installing other
SAN Volume Controller components. You can test the redundant ac-power switch
later if a suitable test device is not available.
About this task
You can test whether the redundant ac-power switch correctly switches between
power inputs when the main input power fails or is restored. You can either use a
volt meter to measure for voltage at the output or attach a work light, or similar
device with a C14 plug, to the redundant ac-power switch output and verify that it
remains powered when a failure is simulated on either of the inputs.
Notes:
v If you do not have a separate device to verify that there is power on the output
port of the redundant ac-power switch, you can delay this test until you connect
the redundant ac-power switch to the uninterruptible power supply. In that case,
turn on the uninterruptible power supply (not the SAN Volume Controller node)
and see if it changes to battery power. The test fails if the uninterruptible power
supply switches to battery power for more than five seconds.
v Any transient indications of battery power can be ignored.
When the instructions say to “remove power,” you can either turn the power off if
the site power-distribution unit (PDU) has outputs that are individually switched
or remove the specified redundant ac-power switch power cable from the outlet of
the site PDU.
Note: If at any time there is no power on the output socket, ensure that the power
distribution sockets of the power source are turned on. If they are, recheck all of
the connections and decide if the redundant ac-power switch assembly, which
includes the input-power cables, is defective.
Perform the following steps to test the redundant ac-power switch:
Procedure
1. Confirm that there is power at redundant ac-power switch output socket 2.
2. Confirm that there is power at redundant ac-power switch output socket 1.
3. Remove power from the main power cable to the redundant ac-power switch
and confirm that there is power at the redundant ac-power switch output 1.
4. Reconnect the main power cable.
5. Remove power from the backup power cable to the redundant ac-power switch
and confirm that there is power at the redundant ac-power switch output 1.
6. Reconnect the backup power cable and remove the monitoring device.
Note: After any failure, repeat the test phase from the start until all the tests
succeed.

Installation guidelines
Before you install the support rails for the SAN Volume Controller 2145-CG8 node,
review the following guidelines:
Before you begin
v Do not install a unit in a rack where the internal-rack ambient temperature
exceeds the lowest manufacturer-recommended ambient temperature for all of
your rack-mounted devices.
v Do not install a unit in a rack where the air flow is compromised. Ensure that
air flow is not blocked or reduced on any side, front, or back of a unit used for
air flow through the unit.
v Ensure that the equipment is connected properly to the supply circuit so that the
circuits do not overload and compromise the supply wiring or overcurrrent
protection.
v Plan the device installation by starting at the bottom of the rack cabinet to
ensure that the rack is stable and cannot tip over.
v Install the heaviest device in the bottom of the rack cabinet.
v Do not install a SAN Volume Controller node directly above the pull-out
monitor and keyboard of the IBM System Storage Productivity Center (SSPC)
server. The front panel of the node protrudes beyond the front of the rack and
overlaps part of the monitor, which prevents you from opening it.
