Cisco UCS 6600 Series Fabric Interconnects

The Cisco UCS 6652 and 6664 Fabric Interconnects are a core part of the Cisco Unified Computing System, providing both network connectivity and management capabilities for the system. The Cisco 6600 series offer line-rate, low-latency, lossless 10/25/40/50/100/400 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE), and 16/32/64 Fibre Channel.

The Cisco UCS 6600 Series Fabric Interconnect provides the management and communication backbone for the Cisco UCS X/B-Series blade servers, UCS 5108 B-Series Chassis, UCS X9508 X-series chassis and UCS C-Series Rack Servers. All servers attached to a Cisco UCS 6600 series Fabric Interconnect become part of a single, highly available management domain. In addition, by supporting a unified fabric, Cisco UCS 6600 series Fabric Interconnect provides both the LAN and SAN connectivity for all servers within its domain.

From a networking perspective, the Cisco UCS 6600 series fabric interconnect uses a cut-through architecture, supporting deterministic, low-latency, line-rate 10/25/40/50/100/400 Gigabit Ethernet ports, a bandwidth of 11.65 Tbps per FI for 6664 FI and 8.44 Tbps per FI for 6652, independent of packet size and enabled services. It enables 1600 Gbps bandwidth per X9508 chassis per domain with a X9108-IFM-100G in addition to enabling end-to-end 100G ethernet and 200G aggregate bandwidth per X-series compute node for 6664 FI. With X9108-IFM-25G it enables 400 Gbps bandwidth per chassis per FI domain for both 6652 and 6664 FI. The product family supports Cisco low-latency, lossless 10/25/40/50/100/400 Gigabit Ethernet unified network fabric capabilities, which increase the reliability, efficiency, and scalability of Ethernet networks. The fabric interconnect supports multiple traffic classes over a lossless Ethernet fabric from the server through the fabric interconnect. Significant TCO savings come from Cisco's unified fabric design in which Network Interface Cards (NICs), Host Bus Adapters (HBAs), cables, and switches can be consolidated.

Cisco UCS 6652 52-Port Fabric

Interconnect The Cisco UCS 6652 Fabric Interconnect (FI) is a 1-RU top-of-rack switch that mounts in a standard 19-inch rack. The 6652 is a 10/25/50/40/100/400 Gigabit Ethernet, FCoE and 16/32/64G Fiber Channel switch offering up to 8.44 Tbps throughput and up to 52 ports. The switch has 16 unified ports (port numbers 17-32) that can support 10/25/40/50G-Gbps SFP28 Ethernet ports or 16/32/64-Gbps Fibre Channel ports, 32 10/25/50-Gbps Ethernet SFP28 ports (port numbers 1-16 and 33-48) and 4 uplink ports that can support 40/100/400-Gbps QSFP-DD Ethernet uplink (port numbers 49-52).

The Cisco UCS 6652 Fabric Interconnect also has one network management port, one console port for setting the initial configuration, and one USB port for saving or loading configurations. The FI also includes L1/L2 ports for connecting two fabric interconnects for high availability.
