DC SAN Director Switch 10/24 FCoE Blade and 2408 FCoE Converged Network Switch fabric rules This section describes the fabric rules for the DC SAN Director Switch 10/24 FCoE Blade and 2408 FCoE Converged Network Switch, and other factors you should consider when building FCoE switch fabrics. The DC SAN Director Switch 10/24 FCoE Blade has 24 CEE ports that are accessible externally. The 2408 FCoE Converged Network Switch has 24 CEE ports and eight 8 Gb/s Fibre Channel ports. Table 39 lists the rules for creating a SAN with the DC SAN Director Switch 10/24 FCoE Blade and 2408 FCoE Converged Network Switches. Table 39 DC SAN Director Switch 10/24 FCoE Blade and 2408 FCoE Converged Network Switch fabric rules Rule number Description 1 A 2408 FCoE Converged Network Switch or DC SAN Director Switch 10/24 Blade can be a standalone switch or an edge switch in a Fibre Channel fabric. To attach the switch to an existing Fibre Channel fabric as an edge switch, at least one Fibre Channel port on the FCoE CN switch must be connected to a Fibre Channel switch in the fabric (E_Port). There cannot be any other FCoE or 10 GbE CEE switches in the path to the Fibre Channel switch. Similarly, a DC or DC04 SAN Director with a 10/24 FCoE Blade installed can be a standalone switch, an edge switch, or a core switch in a Fibre Channel fabric. If it is an edge switch or core switch, other switches in the fabric can be attached to any available FC port (E_Port) on other FC blades in the director. 2 Server CNAs must be directly connected to the CEE ports on a 2408 FCoE Converged Network Switch or DC SAN Director Switch 10/24 FCoE Blade. 3 Fibre Channel storage can be directly connected to the 2408 FCoE Converged Network Switch (one of the eight FC F_Ports) or to any Fibre Channel switch that is part of the same fabric as the 2408 FCoE Converged Network Switch. With the DC SAN Director Switch 10/24 FCoE Blade, storage can be connected to any of the other FC blades in the same director or to any Fibre channel switch that is part of the same fabric as the DC SAN Director that contains the DC SAN Director Switch 10/24 FCoE Blade. 4 Supports a maximum of seven switch hops (eight switches) between a CNA and storage. 5 Supports the following CEE media types: • HP B-series hot pluggable, 10 GbE SFP+ Short Reach (SR) and Long Reach (LR) optical transceivers • HP B-series SFP+ 1 m, 3 m, or 5 m Copper Twinax active cables (2408 FCoE Converged Network Switch only) 6 Up to 4,000 VLANs, but only one FCoE VLAN is currently supported 7 Only FPMA is currently supported.
