Cisco Part Number: UCS-FI-64108-U

Overview
The Cisco UCS 6454 and 64108 Fabric Interconnects are a core part of the Cisco Unified Computing System,
providing both network connectivity and management capabilities for the system. The Cisco UCS 6454 and
64108 offer line-rate, low-latency, lossless 10/25/40/50/100 Gigabit Ethernet, Fibre Channel over Ethernet
(FCoE), and Fibre Channel functions.
These Cisco Fabric Interconnects provide the management and communication backbone for the Cisco UCS
B-Series Blade Servers, UCS 5108 B-series server chassis, UCS Managed C-Series rack servers, and UCS
S-Series storage servers. All servers attached to the Cisco UCS 6454 and 64108 Fabric Interconnects become
part of a single, highly available management domain. In addition, by supporting unified fabric, the Cisco
Fabric Interconnects provide both the LAN and SAN connectivity for all servers within its domain.
From a networking perspective, the Cisco UCS 6454 and 64108 use a cut-through architecture, supporting
deterministic, low-latency, line-rate 10/25/40/50/100 Gigabit Ethernet ports, switching capacity of 3.82
Tbps for the 6454, 7.42 Tbps for the 64108, and 200 Gbps bandwidth between the FI 6454 or 64108 and the
IOM or 2408 Fabric Extender per 5108 blade chassis, independent of packet size and enabled services. The
product family supports Cisco® low-latency, lossless 10/25/40/50/100 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 an FCoE optimized server design in which
network interface cards (NICs), host bus adapters (HBAs), cables, and switches can be consolidated.
