Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters of various operating systems to the same fabric using

appropriate zoning and LUN security as follows:

• Storage port zones may overlap if more than one operating system needs to

share an arra

yport.

• Heterogeneous operating systems m ay share an XP array port if you use Secure

Manager a nd set the appropriate host group and mode. All others must connect

to a dedicat

ed XP array por t.

• Use Secure Manager for LUN isolation when multiple hosts connect through a

shared array p ort. Secure Manager provides LUN security by allowing you to

restrict w

hich LUNs each host ca n a ccess.

• QLogic and Emulex H BAs must be in separate zones (a QLogic zone and an

Emulex zone) whether the HBAs are in the same or separate servers.

• If bootin

g from the array, the bo oting HBAs must be from the same vendor.

Additio

nal data storage HBAs can be fro m 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 g roups. Within

a cluster, each server is a node. Multiple clusters compose a multi-cluster

enviro

nment. The following example shows a multi-cluster environment with three

clusters, each containing two nodes. The nodes share access to the disk array.
