NOTE
The port diagram on the front panel uses the abbreviations GE for 1-GbE ports and 10 GE for 10-GbE
ports.
NOTE
The 10-GbE SFPs used in the FX8-24 blade and the 10-Gbps FC SFPs used in the FC16-32/48
blades are not interchangeable.
The FX8-24 operates in one of three modes: 1) ten 1-GbE ports, 2) ten 1-GbE 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 10-GbE mode, the other end of the circuit must also be an FX8-24 operating in either
10-GbE mode or dual mode with the corresponding VE_ports in 10-GbE 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
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 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
