C-series VSANs with IVR
VSANs are groups of switch ports from one or more C-series switches. Each VSAN has a unique set
of fabric services. Different fabric settings can be applied to each VSAN. This provides a high level
of isolation between VSANs. This isolation can be viewed as individual Fibre Channel subnetworks
within a C-series fabric.
The IVR feature enables you to configure devices in one VSAN for access to devices in another VSAN.
All C-series switches include the VSAN feature. IVR is an optional licensed software feature. There is
no need for additional hardware.
Switch models and fabric topologies
HP supports VSANs with all C-series switches in either HP standard or customized topologies. You
must follow all C-series and VSAN fabric rules.
For more information about VSANs, see
“C-series Fibre Channel and FCoE switches and fabric rules” on page 135.
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 Table 14 on page 89. You must follow all H-series switch
fabric rules. For more information, see “H-series switches and fabric rules” on page 83.
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
nl
isolation and centralized fabric management
