System architecture
Table 16 describes the system architecture of the PowerConnect B-DCX-4S.
TABLE 16 System architecture
Fibre Channel Ports Up to 192 ports, universal (E_Port, F_Port, FL_Port, EX_Port, and M_Port)
Control Processor Redundant (active/standby) control processor modules
Scalability Full fabric architecture: 239 switches maximum
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
