Hi,  In principle single hba / target zoning, for obvious reasons.  But you are using a DS-6520B, so you should be able to upgrade to FOS 7.4. And FOS 7.4 can use "peer zones". these are zones, with single initiator / multiple targets. This is all described on page 351 of the FOS 7.4 Administrator guide, downloadable from the EMC support site. Quote: " Peer Zoning allows a "principal" device to communicate with the rest of the devices in the zone. The principal device manages a Peer Zone. Other "non-principal" devices in the zone can communicate with the principal device only; they cannot communicate with each other. " This will give you easier zoning and less RSCN, to the other devices in the zones. I believe this is your best option.  Best Regards,  Ed
Just wondering how other folks are doing their zoning.  Is it better to use a single initiator/single target or single initiator/multiple target when creating a zone?  Example: ESXi host has HBA1 and HBA2 Two Brocade 6520 FC switches (two fabrics): SW1 and SW2 EMC VMAX with eight FC ports (1-4 on SW1 and 5-8 on SW2)  Create four zones on SW1: one for each initiator/target pair Create four zones on SW2: one for each initiator/target pair. Total of eight zones. Or Create one zone on SW1: one initiator and four targets Create one zone on SW2: one initiator and four targets Total of two zones  For 30 hosts, that's 240 zones versus 60 zones.  Thanks in advance for any feedback.
