Cisco Unified Computing System overview
The Cisco Unified Computing System™ (Cisco UCS®) is a next-generation data center platform that unites computing, networking, storage access, and virtualization resources into a cohesive system designed to reduce Total Cost of Ownership (TCO) and increase business agility. The system integrates a low-latency, lossless 10/25/40/50/100 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multi-chassis platform in which all resources participate in a unified management domain (Figure 1).
The Cisco UCS 6600 Series Fabric Interconnects are a core part of the Cisco Unified Computing System, providing both network connectivity and management capabilities for the system (Figure 2). The Cisco UCS 6600 Series offer line-rate, low-latency, lossless 10/25/40/50/100 Gigabit Ethernet, 16/32/64G Fibre Channel, NVMe over Fabric, and Fibre Channel over Ethernet (FCoE) functions.
The Cisco UCS 6600 Series provide the management and communication backbone for the Cisco UCS X-Series Blade Servers, UCS 9508 X-Series Server Chassis and UCS Managed 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.
UCS Unified fabric: I/O consolidation
The Cisco UCS 6600 series Fabric Interconnects are built to consolidate LAN and SAN traffic onto a single unified fabric, saving on Capital Expenditures (CapEx) and Operating Expenses (OpEx) associated with multiple parallel networks, different types of adapter cards, switching infrastructure, and cabling within racks. The unified ports allow ports in the fabric interconnect to support direct connections from Cisco UCS to existing native Fibre Channel SANs. The capability to connect to a native Fibre Channel protects existing storage-system investments while dramatically simplifying in-rack cabling.
UCS 6600 series Fabric Interconnects support I/O consolidation with end-to-end network virtualization, visibility, and QoS guarantees for the following LAN and SAN traffic.
● FC SAN, IP Storage (iSCSI, NFS), NVMEoF (NVMe/FC, NVMe/TCP, NVMe over ROCEv2)
● Server management and LAN traffic
The I/O consolidation under the UCS 6600 series fabric interconnects along with the stateless policy-driven architecture of UCS and the hardware acceleration of the UCS Virtual Interface card provides great simplicity, flexibility, resiliency, performance, and TCO savings for the customer’s compute infrastructure.

Management Options
Intersight Managed Mode
The Cisco UCS 6600 series Fabric Interconnects can be managed through Cisco Intersight. The UCS 6600 series Fabric Interconnects support Intersight Managed Mode (IMM), which enables full manageability of Cisco UCS elements behind the UCS 6600 series Fabric Interconnects through Cisco Intersight.
UCS 6600 series Fabric Interconnects in Intersight managed mode will support Cisco UCS product models, including Cisco UCS X-Series Servers, and C-Series Rack Servers, as well as the associated storage resources and networks.
Cisco UCS Manager
The Cisco UCS 6600 series Fabric Interconnects host and run Cisco UCS Manager in a highly available configuration, enabling the fabric interconnects to fully manage all Cisco UCS elements.
Cisco UCS Manager (UCSM) on UCS 6600 series Fabric Interconnects will support Cisco UCS product models, including Cisco UCS X-Series Servers and C-Series Rack Servers, as well as the associated storage resources and networks.
Cisco UCS Manager typically is deployed in a clustered active/passive configuration on redundant fabric interconnects connected through dual 10/100/1000 Ethernet clustering ports.
Connectivity
Connectivity for the Cisco UCS X9508 X-series chassis is maintained through the Cisco UCS X9108-IFM-100G or X9108-IFM-25G Intelligent Fabric Module (IFM) in each X-series chassis.
The Cisco UCS C-series servers can directly connect to UCS 6600 series Fabric Interconnects through the UCS VIC 1400 series or the VIC 15000 series. The Cisco UCS C-series servers can also connect to the FI 6600 using the Cisco Nexus 93180YC-FX3 in FEX-mode.
The Cisco UCS 6600 series Fabric Interconnects support out-of-band management, through a dedicated 10/100/1000-Mbps Ethernet management port, as well as in-band management.
Cisco UCS 6664 64-Port Fabric Interconnect
The Cisco UCS 6664 Fabric Interconnect (FI) is a 2-RU top-of-rack switch that mounts in a standard 19-inch rack such as the Cisco R Series rack. The 6664 is a 10/25/40/50/100 Gigabit Ethernet, FCoE and 16/32/64G Fibre Channel switch offering up to 11.65 Tbps throughput and up to 64 ports. The switch has 16 unified ports (port numbers 25-40) that can support 10/25/50-Gbps SFP Ethernet ports or 16/32/64-Gbps Fibre Channel ports, 48 40/100-Gbps Ethernet QSFP ports (port numbers 1-24 and 41-64). All Ethernet ports are capable of supporting FCoE.
The Cisco UCS 6664 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. It also includes L1/L2 ports for connecting two fabric interconnects for high availability.
From a networking perspective, the Cisco UCS 6664 FI use a cut-through architecture, supporting deterministic, low-latency, line-rate 10/25/40/50/100 Gigabit Ethernet ports, switching capacity of 11.65 Tbps, independent of packet size and enabled services. It enables 1600Gbps bandwidth per X9508 chassis with X9108-IFM-100G in addition to enabling end-to-end 100G ethernet and 200G aggregate bandwidth per X210c compute node. With the X9108-IFM-25G and the IOM 2408, it enables 400Gbps bandwidth per chassis per FI domain. The product family supports Cisco® low-latency, lossless 10/25/40/50/100 Gigabit Ethernet unified network fabric capabilities, which increases the reliability, efficiency, and scalability of Ethernet networks. The 6664 FI supports multiple traffic classes over a lossless Ethernet fabric from the server through the fabric interconnect. Significant TCO savings come from the Unified Fabric optimized server design in which Network Interface Cards (NICs), Host Bus Adapters (HBAs), cables, and switches can be consolidated.
