Switch zoning limitations for Xiotech ISEstorage systems

Limitations exist in switch zoning for the clustered systems and the Xiotech ISEstorage system.

Fabric zoning

To avoid a single point of failure, the system's switch zone must include both target ports from each Xiotech ISE controller.

Target port sharing

Target ports can be shared between the system and other hosts.

Host splitting

To avoid the possibility of an interaction between multipathing drivers, a single host cannot be connected to both the system and the Xiotech ISE system.

Controller splitting

Xiotech ISE system logical unit numbers (LUNs) that are mapped to the system cannot be mapped to other hosts. Xiotech ISE system LUNs that are not mapped to the system can be mapped to other hosts.
