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.
