Table 20. System architecture (continued)
Performance 1.063 Gbps line speed, full duplex
2.125 Gbps line speed, full duplex
4.25 Gbps line speed, full duplex
8.50 Gbps line speed, full duplex
10.51875 Gbps line speed, full duplex (with FC10-6
blade)
Autosensing of 1, 2, 4, and 8 Gbps port speeds
optionally programmable to fixed port speed, speed
matching between 1, 2, 4, and 8 Gbps port speeds. Range
depends on use of 4 Gbps or 8 Gbps SFPs.
ISL Trunking Can use up to 8 ports in a trunk group to form a 64
Gbps trunk
Aggregate bandwidth 4.09 Tbps per chassis
Switch latency FC8-16, FC8-32, FC8-48, FC8-64 blades:
<2.1 msec any port to any port at 8 Gbps, cut-through
routing.
For the FR4-18i blade:
<3.6 msec any port to any port at 4 Gbps, cut-through
routing.
For the FX8-24 blade:
<2.1 msec any port to any port at 8 Gbps, cut-through
routing.
For the FCOE10-24 blade:
CEE to CEE and FCOE to FC, <5 msec any port to any
port at 10 Gbps, cut-through routing
Maximum frame size 2112-byte payload
Frame buffers 2048 per ASIC, dynamically allocated.
Classes of service Class 2, Class 3, Class F (interswitch frames)
