HP StorageWorks Disk Array XP operating system configuration guide for Windows 2000/2003 XP24000, XP12000, XP10000, SVS200, v01 (A5951-96195, June 2007)

Fabric zoning 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 with the following restrictions:
• 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.
• QLogic and Emulex HBAs must be in separate zones (a QLogic zone and an Emulex zone) whether
the 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.
