Switch zoning limitations for NetApp FAS systems

Fabric zoning

The system's switch zone must include at least one target port from each filer to avoid a single point of failure.

Sharing of target ports

Target ports can be shared between the system and other hosts. However, you must define separate initiator groups (igroups) for the system's initiator ports and the host ports.

Host splitting

A single host cannot be connected to both the system and the NetApp FAS to avoid the possibility of an interaction between multipathing drivers.

Controller splitting

You can connect other hosts directly to both the NetApp FAS and the system under the following conditions:

• Target ports are dedicated to each host or are in a different igroup than the system.
• LUNs that are in the system igroup are not included in any other igroup.
