Enhanced trunking support for the HP StorageWorks SAN Director 48 Port 4Gb FC blade in the HP
StorageWorks 4/256 SAN Director is summarized in
Director and the HP StorageWorks DC04 SAN Director Switch supports 8 Gb/s. The HP StorageWorks
SAN Director 48 Port 4Gb FC blade does not support 8 Gb/s.

Trunking over distance for the HP StorageWorks 4/256 SAN Director with supported blades

Mode Distance
LE 10 km
L0 Normal
LD 200 km
LD 250 km
LD 500 km
LS Static
NOTE: The L0 mode supports up to 5 km at 2 Gb/s, up to 2 km at 4 Gb/s, and up to 1 km at 8 Gb/s.
The distance for the LS mode is static. You can specify any distance greater than 10 km, for example 25
km, 50 km, and 100 km.
The HP StorageWorks DC04 SAN Director Switch supports long-distance modes LO, LE, LS, and LD.

F_Port masterless trunking

On edge switches, the masterless trunking feature is called F_Port masterless trunking because it trunks
F_Ports; on the switches running in Access Gateway mode, this feature is called Access Gateway N_Port
trunking because it trunks the N_Ports.
F_Port trunking provides a trunk group between a switch (N_Port) in Access Gateway (AG) mode and
Condor-based platforms. This feature keeps F_Ports from becoming disabled when they are mapped to an
N_Port on a switch in Access Gateway mode. With F_Port trunking, any link within a trunk can go offline
or become disabled, but the trunk remains fully functional and there are no reconfiguration requirements.
F_Port trunking prevents reassignments of the Port ID (also referred to as the Address Identifier as described
in Table 89 on page 449) when F_Ports go offline, and it increases F_Port bandwidth. This feature supports
the following:
• HP StorageWorks SAN Switch 4/32
• HP StorageWorks 4/64 SAN Switch
• HP StorageWorks SAN Switch 4/32B
• HP StorageWorks 8/40 SAN Switch
HP StorageWorks 8/80 SAN Switch
•
• HP StorageWorks 8/8 and 8/24 SAN Switches
