20 Buffer credit management TABLE 88 Buffer credits (Continued) Switch/blade model Total FC ports (per switch/blade) FS8-18 16 FX8-24 12 User port group size 8 12 Unreserved buffers (per port group) 1604 1060 For the FC8-x blades, the first number in the Unreserved buffers column designates the number of unreserved buffers per port group in Brocade DCX and DCX-4S platforms; the second number designates the unreserved buffers in a Brocade 48000 director. For example, for the FC8-48, 1228 designates the number of unreserved buffers per port group and 1324 number designates the number in a Brocade 48000 director. Additional buffers are available with the Brocade 48000 director because of fewer buffers allocated for back-end port connections. Implementing extended fabrics between Brocade 2xxx switches and switches running any Fabric OS v6.x is not supported. Maximum configurable distances for Extended Fabrics Table 89 shows the maximum supported extended distances that can be configured for one port on a specific switch or blade at different speeds.
