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.
