Switch zoning limitations for the EMC Symmetrix and Symmetrix DMX
There are limitations in switch zoning for the Storwize® V3700 and the EMC Symmetrix and Symmetrix DMX systems.
Switch zoning
The Storwize V3700 switch zone must include at least one target port on two or more Fibre Channel adapters to avoid a single point of failure.
The EMC Symmetrix and Symmetrix DMX must be configured to present logical units (LUs) to all Storwize V3700 initiator ports that are in the fabric zone.
Only Storwize V3700 initiator ports that are LUN masked on the EMC Symmetrix or Symmetrix DMX controller should be present in the fabric zone.
Connecting to the SAN
You can connect a maximum of 16 EMC Symmetrix or Symmetrix DMX ports to the Storwize V3700 system. There are no further special zoning requirements. Configurations that are set up to adhere to the requirements that are described in previous Storwize V3700 releases are also supported, but should not be followed for new installations.
