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 10/25/40/50/100/400 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 10/25/40/50/100/400 Gigabit Ethernet, 16/32/64G Fibre Channel, NVMe over Fabric, and Fibre Channel over Ethernet (FCoE) functions.
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/B-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.
Connectivity to the Cisco UCS 5108 Blade Server Chassis is maintained through the Cisco UCS 2408 Series Fabric Extenders in each blade 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 UCS 6600 Fabric Interonnects (FIs) 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.
The Cisco UCS 6600 Series Fabric Interconnect offers two different port-speed configurations tailored to the needs of the UCS compute infrastructure. Cisco UCS 6652 Fabric Interconnect delivers a modernized, cost-effective upgrade path for customers operating at 10/25/50G ethernet and 64G FC. For environments moving toward 100G ethernet connectivity and 64G FC, the Cisco UCS 6664 Fabric Interconnect provides a higher-bandwidth option—both are built on the same next-generation Cisco cloud-scale ASIC.
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 such as the Cisco® R Series rack. The 6652 is a 10/25/50 Gigabit Ethernet, FCoE, and 16/32/64G Fibre 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 10/25/50 Gbps SFP Ethernet ports or 16/32/64 Gbps Fibre Channel ports, 32 10/25/50 Gbps Ethernet SFP ports (port numbers 1–16 and 33–48) and 4 QSFP-DD 40/100/400 Gbps Ethernet uplink ports (port numbers 49–52). All Ethernet ports are capable of supporting FCoE.
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. It also includes L1/L2 ports for connecting two fabric interconnects for high availability.
From a networking perspective, the Cisco UCS 6652 FI uses a cut-through architecture, supporting deterministic, low-latency, line-rate 10/25/50 Gigabit Ethernet ports and a switching capacity of 8.44 Tbps, independent of packet size and enabled services. It enables 400Gbps bandwidth per Cisco UCS X9508 Chassis with X9108-IFM-25G in addition to enabling end-to-end 25G Ethernet and 200G aggregate bandwidth per Cisco UCS X210c /X410c compute node. The Cisco UCS 6652 FI provides connectivity for 5108 chassis with IOM-2408 at 25G Ethernet. The C-series rack server can direct-connect or connect via Cisco Nexus 93180YC-FX3 FEX at 10/25G ethernet to the Cisco UCS 6652 FI. In addition to 10/25G speeds the UCS 6652 FI also enables 50G ethernet connectivity for UCS C-series rack server with UCS VIC 15000 series adapter and upgrading to 50G connectivity doubles the ethernet bandwidth at similar cost and power compared to 25G connectivity, and delivers an end-to-end 50G design across ethernet and 64G FC for storage I/O.

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/X410c compute node. With the X9108-IFM-25G and the IOM 2408, UCS 6664 FI enables 400Gbps bandwidth per chassis per FI domain. Additionally, Cisco C-series rack-servers can direct-connect at 10/25/100G to Cisco 6664 FI or via using the Cisco Nexus 93180YC-FX3 in fex-mode.
The Cisco 6600 series FI 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 Cisco 6600 series FI supports multiple traffic classes over a lossless Ethernet fabric from the server through the fabric interconnect. Significant TCO savings come from the Cisco Unified Fabric ̶ optimized server design in which Network Interface Cards (NICs), Host Bus Adapters (HBAs), cables, and switches can be consolidated.
