About SAN Zone and Zonesets
A zone is a collection of ports that can communicate between them over the SAN. We recommend defining a zone per initiator and target, and deploy multiple small zones, rather than having larger zones defined as they consume more resources. A Zoneset is a collection of zones that define the zoning configuration applied to a VSAN. There can be only one active zoneset per VSAN, but there can be multiple zonesets configured in a switch.
Zoning configuration is based on the following characteristics:
-
Enhanced Zoning is enabled for automatic full zoneset distribution and synchronization, and preventing multiple administrators from modifying a VSAN zoneset at the same time. We recommend using enhanced zoning for all configured VSANs in the SAN.
-
Device-aliases are used to configure zoning, as they are independent of the zoning database and can provide naming resolution to applications beyond the zone server.
