Fabric zoning and LUN security for multiple operating systems

You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate zoning and LUN security as follows:

•Host zones must contain only homogeneous operating systems.

•Storage port zones may overlap if more than one operating system needs to share an array port.

•Heterogeneous operating systems may share an XP array port if you use Secure Manager and set the appropriate host group and mode. 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. Secure Manager provides LUN security by allowing you to restrict which LUNs each host can access.

Environment	OS Mix	Fabric Zoning	LUN Security
Standalone SAN	homogeneous (a single OS	Not required	Must be used when multiple
(non-clustered)	type present in the SAN)		hosts connect through a
			shared port
	heterogeneous (more than one	Required
	OS type present in the SAN)
Clustered SAN	homogeneous (a single OS	Not required	Must be used when multiple
	type present in the SAN)		cluster nodes connect through
			a shared port
	heterogeneous (more than one	Required
	OS type present in the SAN)
Multi-Cluster	homogeneous (a single OS	Not required	Must be used when multiple
SAN	type present in the SAN)		cluster nodes connect through

	heterogeneous (more than one	Required
	OS type present in the SAN)
