Soft zoning is the use of
World Wide Names (WWNs) to
allocate resources and control access in a storage-area network (SAN).
With soft zoning, device
assignments can be changed to respond to the varying demands of servers in the network. In comparison, hard
zoning uses switch port numbers
to set up the zone and each
device in the SAN is assigned a permanent zone.
Soft zoning should be used when flexibility is an important factor and security can be ensured
by cooperating hosts but
isn't necessarily a paramount issue.
