FX8-24 blade
The FX8-24 blade has 12 external Fibre Channel (FC) SFP ports supporting the Fibre Channel
Routing Services and 10 external 1 Gigabit Ethernet (GbE or GE) SFP ports supporting the Fibre
Channel Over IP (FCIP) feature. There are also 2 licensable external 10 Gigabit Ethernet (10GbE or
10GE) SFP ports supporting FCIP. It operates with the Brocade Fabric Operating System and can
communicate with another FX8-24 or a Brocade 7800 for both Fibre Channel Routing Services and
FCIP, or a Brocade AP7420 for Fibre Channel Routing Services.The GbE ports on the FX8-24 are
NOT compatible with the GbE ports on the FR4-18i blade or the Brocade 7500 switch.
NOTE
The port diagram on the front panel uses the abbreviations GE for 1 GbE ports and 10GE for 10 GbE
ports.
CAUTION
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 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 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).
