Chapter 1. Preparing to install the SAN Volume Controller
Before installing the SAN Volume Controller, you must meet the hardware,
software, and environmental requirements (including a suitable rack cabinet
physical location). Learning about the controls, indicators, operator-information
panel, and connectors will prepare you for the installation procedures.
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; a minimum of one pair and a maximum of
four pairs of nodes constitute a system. Each pair of nodes is known as an I/O
group.
