Fourth-generation Cisco UCS C-Series Rack Server FEX connect mode
-
The fourth-generation Cisco Nexus 2232PP Fabric Extender allows for a greater number of Cisco UCS C-Series Rack Servers.
Cisco UCS C-Series Rack Server FEX connect mode enables 32 host-capable connections per FEX and six uplink ports.
Cisco UCS C-Series Rack Server FEX connect mode has the following features:
- Cisco Nexus 2232PP 10 GbE Fabric Extenders
- Four or eight 10 Gbps uplinks to the FI
- Cisco UCS port licensing
- 10 Gbps per connection per fabric from M4 servers using the Cisco UCS VIC 1225 or 1227
M5 servers could use VICs 1455 or 1457 to achieve 10 Gbps connectivity.
- Cisco UCS 1455 and 1457 VICs: Ports 1 and 2 connect to FEX A and ports 3 and 4 connect to FEX B
- Cisco UCS 1455 or 1457 single-link connectivity, two-port connection: Port 1 or 2 connects to FEX A and port 3 or 4 connects to FEX B
- Cisco UCS 1455 or 1457 dual-link connectivity, four-port connection: Ports 1 and 2 connect to FEX A and ports 3 and 4 connect to FEX B
The following figure shows a Cisco UCS fourth-generation configuration with Cisco UCS C-Series Rack Servers in FEX connect mode:
