Fabric zonin
g and LUN security
By using appropriate zoning and LUN security, you can connect various servers with various operating
systems to the same switch and fabric:
• Storage por t zones may overlap if more than one operating system needs to share an array port.
• Heterogene
ous operating systems may share a n X P a rray port if you use Secure Manager and set
the appropriate host group and mod e. All others must connect to a dedicated XP array port.
• Use Secure Manager for LUN isolation when multiple hosts connect through a shared array
port. Secu
re Manager provides LUN security by allowing you to restrict which LUNs each host
can access.
• QLogic and Emulex HBAs must be in separate zones (a QLogic zone and an Emulex zone )
whether t
he HBAs are in the same or separate servers.
• If booting over the SAN, within a server, the booting HBAs must be from the same vendor.
Additional data storage HBAs can be from a different vendor.

• 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.
