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. Installing and configuring the host 43

Clustering and fabric zoning
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.
Figure 4 Multi-cluster environment (Novell NetWare)
Within the SAN, the clusters must be homogeneous (all the same operating system). Heterogeneous
(mixed operating systems) clusters are not allowed. How you configure LUN security and fabric
zoning depends on 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.
