Fabric Zoning And Lun Security For Multiple Operating Systems; Multi-Cluster Environment; San Fabric Zoning And Lun Security Settings - HP StorageWorks XP24000 Configuration Manual

Figure 4 Multi-cluster environment
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.
NOTE:
In addition to standard clustering using MSCS (Windows Guest OS), VMware has distinct High Availability
features. For detailed information, see the VMware Resource Management Guide available at:
http://www.vmware.com/support/pubs.

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:
• 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.
