■ Node port (N_Port) switched configuration.
■ Fibre Channel arbitrated loop (FC-AL) configuration.
FC-AL hubs are not supported.
For SAN switched configurations, proper zoning prevents Fibre Transport traffic
from using the bandwidth that may be required for other SAN activity. Proper zoning
also limits the devices that the host bus adapter (HBA) ports discover; the ports
should detect the other ports in their zone only. Without zoning, each HBA port
detects all HBA ports from all hosts on the SAN. The potentially large number of
devices may exceed the number that the operating system supports.
Instructions for how to configure and manage a SAN are beyond the scope of the
NetBackup documentation. However, the following recommendations may help you
optimize your SAN traffic.
Table 3-1 describes the best practices for zoning the SAN on NetBackup appliances.

Best practices for zoning the SAN on NetBackup appliances
DescriptionGuideline
Veritas recommends that you create zones with
only a single initiator per zone. Multiple targets in
a single zone are acceptable, only if all of the
targets are similar.
Note: For data duplication between two
NetBackup 52xx or 53xx appliances, you must
create zones with only one single initiator and one
single target per zone.
Tape target resources should be in separate zones
from disk target resources, regardless of initiator.
However, both sets of resources may share the
same initiator.
One initiator per zone, multiple targets
acceptable.
If you use a single port as an initiator or a target
for multiple zones, this port can become a
bottleneck for the overall performance of the
system. You must analyze the aggregate required
throughput of any part of the system and optimize
the traffic flow as necessary.
Be aware of performance degradation
when a port is configured for multiple
zones.
