.SAN design reference guide Vol. 1-5 785350-001

Benefits
A VSAN:
• Isolates fabric services and minimizes fault propagation
• Allows multiple secure VSANs over the same physical infrastructure
• Restricts device access for improved control and security
• Provides selective device access and sharing using the IVR feature
H-series switches with TR
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 SN6000 Fibre Channel Switch or an 8/20q Fibre Channel 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.
A TR_Port server as a bridge between the transparent router's local fabric and a remote fabric.
The TR_Port uses standard NPIV login methods to connect to the remote fabric. You can configure
any of the 8 Gb ports of the SN6000 Fibre Channel Switch or the 8/20q Fibre Channel Switch
as TR_Ports.
Switch models and fabric topologies
HP supports the SN6000 Fibre Channel Switch or the 8/20q Fibre Channel Switch with TR with
B-series or C-series switches in either HP standard or customized topologies. For the supported
B-series and C-series switches and firmware, see “Supported switches in an H-series switch with
TR remote fabric” (page 147). You must follow all H-series switch fabric rules. For more information,
see “H-series switches and fabric rules” (page 140).
Benefits
H-series switches with TR provide the following benefits:
• Allows fabric connections (without the need to merge fabrics), providing a high level of fault
isolation and centralized fabric management
• Allows connection of fabrics with the same domain ID and zoning definitions
• Reduces the impact of scaling limits for individual fabrics
• Increases levels of storage consolidation
• Provides centralized backup for multiple fabrics
FCoE fabric topologies
FCoE technology allows you to converge Ethernet and Fibre Channel technology, providing
significant cable, adapter, and switch consolidation. All HP-supported Fibre Channel topologies
are supported integrated with FCoE at the Fibre Channel fabric edge. HP also supports end-to-end
FCoE solutions for the P63xx/P65xx EVA storage systems with the FCoE target interface, HP 3PAR
StoreServ Storage systems with the FCoE target interface, HP 3PAR StoreServ Storage systems
using a fabric connection between the MPX200 and Fibre Channel storage, and P6000 EVA
storage using the MPX200 Multifunction Router. For more information about FCoE, see “Fibre
Channel over Ethernet” (page 62).
