The FX8-24 operates in one of three modes: 1) ten 1GbE ports, 2) ten 1GbE ports and one 10 GbE port, or 3) two 10 GbE ports
depending on licensing and subsequent configuration of GbE port mode. If operating in 10GbE mode, the other end of the circuit must
also be an FX8-24 operating in either 10GbE mode or dual mode with the corresponding VE_ports in 10GbE mode. All GbE ports on
the blade can be configured to work with either copper or optical SFPs.
The FX8-24 blade is intended as a platform for FCIP and Fibre Channel Routing Services. Refer to the Brocade Fabric OS
Administration Guide for information on configuring these features.
The FX8-24 blade provides the following hardware features:
• Twelve 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 10 GbE 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
Brocade Fabric OS
Administration 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
