Table 27 B-series Fibre Channel switch fabric rules
DescriptionRule number
A maximum of 56 switches and 2,560 virtual or physical connections in a single fabric with HP
StoreFabric SN6500B 16Gb FC Switch using firmware 7.1.0a (or later), HP SN8000B 8-Slot SAN
1
Backbone Director Switch, HP SN8000B 4-Slot SAN Director Switch, or HP SN6000B 16Gb FC Switch,
or HP SN3000B 16Gb FC Switch using firmware 7.x (or later) or DC SAN Backbone, or DC04 SAN
Directors, 8/8, 8/24, 8/40, 8/80, 4/8, 4/16, 4/32B, 4/64, or 4/256 switches using firmware 6.x
(or later), or 2/64 or 2/128 switches using firmware 5.3.x (or later).
A maximum of 16 DC SAN Backbone Director or DC04 SAN Director chassis, or 6,000 virtual or
physical connections (WWNs logged into a single fabric), are supported in a fabric containing HP
SN8000B 8-Slot Backbone Director, HP SN8000B 4-slot Backbone Director, DC SAN Backbone Directors
or DC04 SAN Directors only.
A maximum of 4,096 virtual or physical connections are supported in a fabric containing other switch
models using firmware 6.1.x (or later).
A maximum of 56 switches and 2,560 virtual or physical connections in a single fabric with 4/8, 4/16,
4/32B, 4/64, 4/256, 2/64, or 2/128 switches using firmware 5.x (or later).
2
8 Gb/s switches and ARB(FF)/ARB(FF) mode setting—HP recommends all 8 Gb/s switches running FOS
6.3.1a and later (6.4.0a and later for XP storage array connectivity) be set to mode 3 using the
3
portcfgfillword command. For more information, see the Fabric OS Command Reference Manual
supporting Fabric OS v6.4 and the FOS release notes.
Note: HP SN8000B 8-Slot SAN Backbone Director Switch, HP SN8000B 4-Slot SAN Director Switch,
HP StoreFabric SN6500B 16Gb FC Switch, HP SN6000B 16Gb FC Switch, or the HP SN3000B 16Gb
FC Switch automatically selects the proper fill word.
HP StorageWorks 4/256 SAN Director—Maximum of 20 chassis per fabric with all 16-port Fibre
Channel blades, maximum of 10 chassis with all 32-port Fibre Channel blades. For all configurations,
4
the maximum number of total virtual or physical connections must not exceed 2,560. Each chassis adds
one switch to the fabric switch count if it is configured as one domain. This switch does not support
port-based routing. See "Routing Traffic" in the HP StorageWorks Fabric OS 5.x Administrator's Guide.
HP StorageWorks 2/128 SAN Director—Maximum of 20 chassis per fabric. Each chassis adds one
switch to the fabric switch count if it is configured as one domain.
