You should also keep the following considerations in mind:

￿Fibre channel SANs can provide the capability to interconnect open systems and storage in the same network as S/390 and zSeries host systems and storage.

￿A single Fibre Channel host adapter can have physical access to multiple Fibre Channel ports on the storage unit.

For some Fibre Channel attachments, you can establish zones to limit the access of host adapters to storage system adapters. By establishing zones, you reduce the possibility of interactions between system adapters in switched configurations.

You can configure switch ports that are attached to the storage unit in more than one zone. This enables multiple system adapters to share access to the storage unit Fibre Channel ports. Shared access to a storage unit Fibre Channel port might come from host platforms that support a combination of bus adapter types and operating systems.
