Figure 6 Remote replication fabrics with redund ant servers
When you connect the local and remote sites with an interswitch link, ensure that the combine d fabric
stays within switch, port, and hop limitations. For fabric topologies, switch and fabric rules, SAN
integration issues, and extended SANs, see HP StorageWorks SAN design reference guide on the HP
SAN Infrastructure web site: h

Create z
ones
Switch zoning allows incompatible resources to coexist in a heterogeneous SAN. Using switch
management software, create separate zones for hosts that are incompatible in a SAN, including in
each zone the arrays that the host will access before and after a failover. Array controller por ts can be
in overlapping zones.
Includ
e ma n agem ent servers in the zones containing hosts and arrays, or create zones exclusively
for ma
nagement servers and the arrays that they mana ge. The HP OpenView Storage Management
Appli
ance, for example, must be zoned separately from hosts. Each m a nagement ser ver must be able
to manage the local and remote arrays, but only one server at a time can manage any array. Include
one active and one standby management server in each management zone. Figure 7 shows a zoning
configuration in which the management servers at the local a nd remote sites are in separate zones with
arrays in both zones. If the management server or links fail at either site, the management server at the
