Table 19. System architecture (continued)
Performance 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.
16.0 Gbps line speed, full duplex.
Autosensing of 2, 4, 8, and 16 Gbps port speeds
depending on SFPs used. Speed matching between 2, 4,
8, and 16 Gbps port speeds. 10 Gbps port speeds with
dedicated SFPs.
ISL Trunking Automatically uses up to 4 ports in a trunk group to
form a 32 Gbps trunk. Can use up to 8 ports in a trunk
group to form a 64 Gbps trunk.
Aggregate bandwidth 8.2 Tbps populated with eight FC16-48 port blades and
using 32 ICL ports @ 64 Gbps).
Switch latency FC8-64 blades:
<2.1 msec any port to any port at 8 Gbps, cut-through
routing.
FC16-32 & FC16-48 blades:
<800 ns any port to any port, 2.4 msec blade to blade at
16 Gbps, cut-through routing.
For the FX8-24 blade - FC to FC:
<2.1 msec any port to any port at 8 Gbps, cut-through
routing.
Maximum frame size 2112-byte payload
Frame buffers 8000 per ASIC, with 5000 more that can be borrowed
from neighboring ASIC if enabled.
Port types FC8-64 supports these port types:
F_Port, FL_Port, E_Port, Ex_Port, and M_Port
FC16-32 and FC16-48 support these port types: F_Port,
E_Port, Ex_Port, M_Port and D_Port.
FX8-24 supports these port types: F_Port, FL_Port,
E_Port, and Ex_Port on FC
VE_Port on GbE
Note:
Self-discovery is based on switch type (U_Port)
with an optional port type control.
Data traffic types Fabric switches supporting unicast, multicast (255
groups), and broadcast
