Installation 25
Fabric zoning and LUN security
If you plan to use clustering, install and configure the clustering software
on the servers.
Clustering is the organization of multiple servers into groups. Within a
cluster, each server is a node. Multiple clusters compose a multi-cluster
environment. The following example shows a multi-cluster environment
with three clusters, each containing two nodes. The nodes share access to
the disk array.
Within the Storage Area Network (SAN), the clusters may be
homogeneous (all the same operating system) or they may be
heterogeneous (mixed operating systems). How you configure LUN
security and fabric zoning depends on the operating system mix and the
SAN configuration.
