Table 54 H-series switches fabric rules (continued)
Description
Rule
number
8/20q Fibre Channel Switch supports from 8 to 20 8 Gb/s ports, in 4-port increments; SN6000 Fibre
Channel Switch supports 8 to 20 8 Gb/s ports, in 4-port increments, plus 4 stacking ports.
3
Within a fabric, if you assign a domain number (domain ID), it must be unique. Do not configure any
switches with a domain ID of 8, which is reserved for HP-UX.
4
For HP StoreVirtual 4000 FC, unique domain IDs are required in the entire Fibre Channel SAN to which
the StoreVirtual storage system is connected, including multiple independent fabrics. Overlapping domain
IDs (even in non-merged/independent fabrics) are not supported.
5
ISL maximums
When designing a fabric using 8-port, 12-port, 16-port, or 20-port switches, you can use up to
six 8 Gb ports per switch as ISLs.
Fabric rules for H-series switches with TR
This section describes the fabric rules for H-series switches with TR connecting to B-series or C-series
fabrics.
The TR feature provides inter-fabric routing on a per-port basis, allowing controlled access between
devices on an H-series switch (local) fabric and devices on a remote fabric consisting of B-series
or C-series switches. The establishment of a routed connection using TR maintains a high level of
isolation between fabrics. A transparent route between two devices consists of a connection from
a TR_Port on an H-series switch to a switch in the remote fabric, a mapping of the two devices to
be routed together, and an IFZ for the routed devices in both fabrics.
Each fabric contains a matching IFZ and each IFZ contains three WWN members: the local device,
the remote device, and the TR_Port connected to the remote fabric. This inter-fabric connection uses
the Fibre Channel industry-standard NPIV, making local and remote devices accessible to each
other and maintaining local and remote fabrics as separate fabrics.
You can connect multiple H-series switches to one or more remote fabrics using multiple TR_Ports.
Local and remote devices are identified by their respective worldwide port names.
You can configure transparent routing using QuickTools, EFMS, or the CLI. HP recommends that
you use QuickTools or EFMS because they validate your entries, manage the zone mapping for
the local fabric, and create a list of zoning commands you can run in a script on a B-series or
C-series SAN switch. For more information and important configuration details, see the following
