FX8-24 blade B The FX8-24 blade is intended as a platform for FCIP and Fibre Channel Routing Services. Refer to the Fabric OS Administrator's Guide for information on configuring these features. The FX8-24 blade provides the following hardware features: • 12 autosensing FC ports with link speeds of 1, 2, 4 or 8 Gbps. • Ten GbE ports supporting FCIP with fixed link speed at 1 Gbps: • Two 10GbE ports (licensable) supporting FCIP with fixed link speed at 10 Gbps. The FX8-24 blade also provides the following functionality features: • FCIP. • Compression (on FC frames before FCIP encapsulation). • FC Routing (licensable). • FCIP Trunking (licensable) with network-based failure recovery (failover only) and load balancing. • Multiple circuits per trunk. • Four per trunk through the GbE ports. • Ten per trunk through the 10 GbE ports. • SO-TCP with reorder resistance. • FastWrite over FCIP. • Tape pipelining over FCIP. • FICON XRC emulation and tape pipelining over FCIP (licensable). • FICON CUP (licensable). • Virtual E_ports. • FCIP QoS. • Support for 200 ms RTT (on a limited number of GbE ports). • Adaptive Rate Limiting (licensable). • TCP performance graphing in Web Tools. • FCIP Tunnels. • A maximum of 10 FCIP Tunnels for all GbE ports. • Four tunnels maximum per GbE port. • Two 10 GbE ports can support up to ten FCIP tunnels each. • Each FCIP tunnel is represented and managed as a virtual Fibre Channel E_Port. • Fibre Channel Routing Services can be used over the FCIP link. • The Link Cost is equal to the sum of all established/low metric (or currently active) circuits' MAX rates in the tunnel. • Fabrics connected through FCIP merge if the ports are configured as VE_Ports, and do not merge if they are configured as VEX_Ports. If VE_Ports are used in a Fibre Channel Routing Services backbone fabric configuration, then the backbone fabric merges, but the EX_Port-attached edge fabrics do not merge. For more information refer to the Fabric OS Administrator's Guide. • Up to three FC trunking groups. The three groups are defined as: • Trunk group 0: FC ports 0,1 • Trunk group 1: FC ports 6,7 PowerConnect B-DCX4S Backbone Hardware Reference Manual 103 53-1001808-01
