NOTE
The port diagram on the front panel uses the abbreviations GE for 1 GbE ports and 10GE 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
