Zoning Rules
■
A minimum of one switch port per zone
■
A maximum of 16 zones per 16-port switch
■
A maximum of 30 zones for cascading 16-port to 16-port switches
■
Port-based and world-wide name (WWN)-based zoning is supported.
■
Server and storage may be in the same name server zone across ISLs on separate
switches. This enables you to have servers at a recovery site. It also means you
can have local and remote storage in the same zone, so that storage can be
mirrored at both locations.
Configuration Guidelines
Switches
For high-availability applications, configure two sets of switches in parallel.
Zones and Arrays
■
Sun StorEdge T3 arrays support name server zones (or zones in which a host has
made a point-to-point Fabric connection to a switch and the Sun StorEdge T3
array is attached to a TL port).
■
Do not mix different arrays in the same zone. A single zone can contain only Sun
StorEdge 3900 arrays, or only Sun StorEdge T3 arrays.
■
You may configure a minimum of one port per zone
For example, a 16-port switch can have a maximum of 16 zones.
