Table 55 Enforcing hardware zoning (continued) Fabric type Methodology Best practice HP StorageWorks 4/8 SAN Switch, 4/16 SAN Switch, Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade 4Gb SAN Switch for HP c-Class BladeSystem, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, 400 MP Router, 8/8 SAN Switch, 8/24 SAN Switch, 8/40 SAN Switch, and 8/80 SAN Switch, 4/256 SAN Director, and the DC SAN Backbone Director (short name, DC Director) Enable hardware-enforced zoning on domain,port zones, and WWN zones. Overlap of similar zone types does not result in the loss of hardware enforcement. Overlap with other zone type results in the loss of hardware enforcement. As in the Brocade 2000-series switches, connecting a device specified by WWN to a port specified in a domain,port zone results in loss of the hardware enforcement in both zones. For the 4/256 SAN Director with an FC4-48 port blade and the DC Director with an FC8-48 port blade: If ports 16 through 47 on the FC4-48 port blade use domain,port identifiers, then session-based zoning is enforced on these ports. Use either WWN or domain,port identifiers. Mixed switches Enable hardware-enforced zoning according to each switch type. Use the portZoneShow command to find the zone type to which a device is attached. Use domain,port identifiers. You can use WWN identifiers if you place disk and tape targets on HP 2Gb and SAN Director 2/128 models, and do not use domain,port identifiers. Figure 11 shows a fabric with four hardware-enforced zones that don't overlap.
