Fabric rules for H-series switches Table 13 describes the rules for creating a SAN with H-series switches. Table 13 H-series switches fabric rules Rule nl number Description 1 Supports up to 30 switches with up to 600 total 8 Gb/s ports, up to 120 10 Gb/20 Gb stacking ports, and up to 512 user ports in a fabric. 2 Supports a maximum of 7 switch hops (8 switches) between any 2 communicating devices. 3 8/20q Fibre Channel Switch supports from 8 ports to 20 ports, in 4-port increments; SN6000 Fibre Channel switch supports 20 ports plus 4 stacking ports. ISL maximums When designing a fabric using 8-port, 12-port, 16-port, or 20-port switches, you can use up to six 8 Gb ports per switch as ISLs. Fabric rules for H-series switches with TR This section describes the fabric rules for H-series switches with TR connecting to B-series or C-series fabrics. 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 H-series 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. Each fabric contains a matching IFZ and each IFZ contains three WWN members: the local device, the remote device, and the TR_Port connected to the remote fabric. This inter-fabric connection uses the Fibre Channel industry-standard NPIV, making local and remote devices accessible to each other and maintaining local and remote fabrics as separate fabrics. You can connect multiple H-series switches to one or more remote fabrics using multiple TR_Ports. Local and remote devices are identified by their respective worldwide port names. You can configure transparent routing using QuickTools or the CLI. HP recommends that you use QuickTools because it validates your entries, manages the zone mapping for the local fabric, and creates a list of zoning commands you can run in a script on a B-series or C-series SAN switch.
