Performance
v 4-Gbps line speed, full duplex
v 8-Gbps line speed, full duplex
v 10-Gbps line speed, full duplex
v 16-Gbps line speed, full duplex
v 32-Gbps line speed, full duplex
v 10-GbE line speed, full duplex
v 25-GbE line speed, full duplex
v 40-GbE line speed, full duplex
Auto sensing of 4-, 8-, 16-, and 32-Gbps port speeds depending on transceiver used.
Speed matching between 4-, 8-, 16-, and 32-Gbps port speeds. 10-Gbps port speeds
with dedicated SFPs.
The 10-GbE speed is accomplished using a 40-GbE QSFP transceiver in breakout
mode to provide 4x10-GbE speed. The 25-GbE speed is accomplished using a 100-GbE
transceiver in breakout mode to provide 4x25-GbE speed.
Slot bandwidth 1,536 Gbps (data rate).
Local switching bandwidth 2 Tbps for FC32-64: 64 ports x 32 Gbps (data rate).
Chassis bandwidth SAN256B-6 Director: 10 Tbps per chassis (256 ports with 32-Gbps data rate plus 16
4x32-Gbps ICLs).
SAN512B-6 Director: 20 Tbps per chassis (512 ports with 32-Gbps data rate plus 32
4x32-Gbps ICLs).
ISL trunking
Can use up to 8 ports in a trunk group to form a 256-Gbps trunk.
