Figure 9 Multi-cluster environment (VMware) Within the SAN, the clusters can be homogeneous (all the same operating system) or heterogeneous (mixed operating systems). How you configure LUN security and fabric zoning depends on the operating system mix and the SAN configuration. Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters with multiple operating systems to the same switch and fabric using appropriate zoning and LUN security as follows: • Storage port zones can overlap if more than one operating system needs to share an array port. • Heterogeneous operating systems can share an array port if you set the appropriate host group and mode. All others must connect to a dedicated array port. • Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port. LUN Manager provides LUN security by allowing you to restrict which LUNs each host can access.

Figure 9 Multi-cluster environment (VMware)
Within the SAN, the clusters can be homogeneous (all the same operating system) or heterogeneous
(mixed operating systems). How you configure LUN security and fabric zoning depends on the
operating system mix and the SAN configuration.
Fabric zoning and LUN security for multiple operating systems
You can connect multiple clusters with multiple operating systems to the same switch and fabric
using appropriate zoning and LUN security as follows:
•
Storage port zones can overlap if more than one operating system needs to share an array
port.
•
Heterogeneous operating systems can share an array port if you set the appropriate host
group and mode. All others must connect to a dedicated array port.
•
Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can
access.
