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 17 (page 47) 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” (page 146). 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.
As shown in Figure 18 (page 49), an LSAN can include devices connected to different fabrics (for
example, the LSAN Zone connects devices from Fabric 1 and Fabric 2).

Figure 19 (page 50) and Figure 20 (page 50) show the differences between B-series MP Router
and C-series routing.
Figure 19 (page 50) 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.
