System architecture TABLE 18
Feature Description
Fibre Channel
Ports Up to 512 16-Gbps ports, universal (E_Port, F_Port, EX_Port, M_Port, D_Port, FICON).
Control Processor Redundant (active/standby) control processor blades.
Scalability Full fabric architecture: 239 switches maximum.
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 QSFP to form a 64 Gbps trunk. Can use up to two
QSFPs; 8 ports in a group to form a 128 Gbps trunk.
Aggregate
bandwidth 10 Tbps populated with eight FC16-64 port blades and using 32 ICL ports @ 64 Gbps).
Switch latency FC8-32E, FC8-48E, and FC8-64 blades:
<700 ns any port to any port local switching and 2.1 µsec blade to blade at 8-Gbps, cut-
through routing.
FC16-32, FC16-48, and FC16-64 blades:
<700 ns any port to any port local switching and 2.1 µsec blade to blade at 16-Gbps, cut-
through routing.
FX8-24 blade - FC to FC:
<2.1 µsec any port to any port at 8 Gbps, cut-through routing.
FCOE10-24 blade - CEE to CEE (different ASIC) and FCoE to FC:
<5 μsec any port to any port at 8 Gbps, cut-through routing.
Maximum frame
size 2112-byte payload.
Frame buffers 8000 per Gen 5 ASIC, with 5000 more that can be borrowed from neighboring ASIC if
enabled.
