Limitations exist in switch zoning for SAN Volume Controller clusters and the Xiotech Emprise storage system.
To avoid a single point of failure, the SAN Volume Controller switch zone must include both target ports from each Xiotech Emprise controller.
Target ports can be shared between the SAN Volume Controller cluster and other hosts.
To avoid the possibility of an interaction between multipathing drivers, a single host cannot be connected to both the SAN Volume Controller cluster and the Xiotech Emprise system.
Xiotech Emprise system logical unit numbers (LUNs) that are mapped to the SAN Volume Controller cluster cannot be mapped to other hosts. Xiotech Emprise system LUNs that are not mapped to the SAN Volume Controller cluster can be mapped to other hosts.
