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.
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
