C-Series Vsans With Ivr; H-Series Switches With Tr - HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays Reference Manual

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
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
fabric rules. For more information, see
