describes the system architecture of the PowerConnect B-DCX-4S.
System architecture
Up to 192 ports, universal (E_Port, F_Port, FL_Port, EX_Port, and M_Port)
Redundant (active/standby) control processor modules
Full fabric architecture: 239 switches maximum
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
Can use up to 8 ports in a trunk group to form a 64 Gbps trunk
3 Tbps per chassis
FC8-16 blade:
<2.1 µsec any port to any port at 8 Gbps, cut-through routing.
FC8-32 blade:
<2.1 µsec any port to any port at 8 Gbps, cut-through routing.
FC8-48 blade:
<2.1 µsec any port to any port at 8 Gbps, cut-through routing.
FA4-18 blade:
<3.6 µsec any port to any port at 4 Gbps, cut-through routing.
FR4-18i blade:
<3.6 µsec any port to any port at 4 Gbps, cut-through routing.
FX8-24 blade;
<700 ns any port to any port at 8 Gbps, cut-through routing.
FFCOE10-24 blade - CEE to CEE (different ASIC) and FCoE to FC:
<5 µsec any port to any port at 10 Gbps, cut-through routing.
2112-byte payload
2048 per ASIC, dynamically allocated
Class 2, Class 3, Class F (interswitch frames)
