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 SAN Design Reference Guide 51
