Fabric Extenders
Several Cisco UCS fabric extenders can be connected to Cisco UCS 6300 Series
Fabric Interconnects.
Fabric Interconnects.
•
Cisco UCS 2304 Fabric Extender: For blade chassis, the Cisco UCS 2304
provides 160 Gbps of bandwidth to each of the two fabrics in a Cisco UCS 5108
Blade Server Chassis, for up to 320 Gbps of bandwidth. Each fabric extender
provides eight 40-Gbps server links and four 40-Gbps SFP+ uplinks to the
fabric interconnects (Figure 6). Server links are supported by multiple 10GBASE-
KR connections across the blade chassis midplane. These connections are
combined into 40-Gbps links when Cisco UCS VIC 1340s are used with the
optional Port Expander Card, or left as 10-Gbps links otherwise. In addition to
extending the network to blade servers, the fabric extender contains logic that
extends the management network from Cisco UCS Manager into each server’s
Cisco integrated management console.

Cisco Nexus 2348UPQ 10GE Fabric Extender: For Cisco UCS rack servers
and other appliances, the Cisco Nexus 2348UPQ 10GE connects to the fabric
interconnects with up to 240 Gbps of bandwidth and 1- and 10-Gbps unified
fabric downstream to Cisco UCS C-Series Rack Servers. Each fabric extender
provides forty-eight 1- and 10-Gbps unified port interfaces (SFP+) and six 10-
and 40-Gbps unified fabric interfaces (QSFP+).
