H-series switch fabric routing
You can configure any H-series switch 8 Gb port as a TR_Port, which you use to connect devices on
the H-series switch to devices on a remote fabric. You do this by configuring TR mapping, which
establishes a route to connect one device on the H-series switch to one device on a remote fabric
through one TR_Port. Multiple devices can share TR_Ports, and you can configure multiple TR_Ports
to the same remote fabric. HP currently supports connection to B-series and C-series remote fabrics.
Figure 19 shows how one or more remote fabrics can connect to an H-series switch. Remote Fabric
1, Remote Fabric 2, and the H-series switch fabric each contain one or more switches. Devices
connected through routing must comply with the configuration rules for the TR function. (See
“Fabric rules for H-series switches with TR” on page 88.) The fabrics can have identical domain names
and zoning definitions.
B-series, C-series, and H-series routing differences
B-series 8 Gb/s switches with integrated Fibre Channel routing, 1606 Extension SAN Switches or
DC Dir Switch MP Extension Blades, an MP Router, Virtual Fabrics with IFR, or VSANs with IVR can
connect existing fabrics or VSANs. When existing fabrics are connected to an 8 Gb/s switch with
Fibre Channel routing or MP Router, it creates a Meta SAN. Using B-series switches with Virtual Fabrics
or C-series switches with VSANs, existing fabrics are physically connected, and the routing function
in the switches is configured using IFR or IVR.
Figure 21 and Figure 22 show the differences between B-series MP Router and C-series routing.

As shown in Figure 20, an LSAN can include devices connected to different fabrics (for example, the
LSAN Zone connects devices from Fabric 1 and Fabric 2).
Figure 21 shows how Virtual Fabrics can include devices that connect to a single switch or multiple
switches in the SAN. Devices in different Virtual Fabrics communicate using IFR. Multiple switches
can be connected in any supported fabric configuration.
