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 Gigabit Ethernet unified network fabric with enterprise-class, x86-architecture servers. The system is an integrated, scalable, multichassis platform in which all resources participate in a unified management domain (Figure 1).
Product Overview
The Cisco UCS 6200 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 6200 Series offers line-rate, low-latency, lossless 10 Gigabit Ethernet, Fibre Channel over Ethernet (FCoE), and Fibre Channel functions.
The Cisco UCS 6200 Series provides the management and communication backbone for the Cisco UCS B-Series Blade Servers and 5100 Series Blade Server Chassis. All chassis, and therefore all blades, attached to the Cisco UCS 6200 Series Fabric Interconnects become part of a single, highly available management domain. In addition, by supporting unified fabric, the Cisco UCS 6200 Series provides both LAN and SAN connectivity for all blades within its domain.
The Cisco UCS 6200 Series uses a cut-through networking architecture, supporting deterministic, low-latency, line‑rate 10 Gigabit Ethernet on all ports, switching capacity of 2 terabits (Tb), and bandwidth of 320 Gbps per chassis, independent of packet size and enabled services. The product family supports Cisco® low-latency, lossless 10 Gigabit Ethernet[1] 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 blade through the 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.
Unified Fabric with FCoE: I/O Consolidation
The Cisco UCS 6200 Series is built to consolidate LAN and SAN traffic onto a single unified fabric, saving the 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 either base or expansion module ports in the interconnect to support direct connections from Cisco UCS to existing native Fibre Channel SANs. The capability to connect FCoE to native Fibre Channel protects existing storage system investments while dramatically simplifying in-rack cabling.
Cisco UCS Manager
The Cisco UCS 6200 Series hosts and runs Cisco UCS Manager in a highly available configuration, enabling the fabric interconnects to fully manage all Cisco UCS elements. Connectivity to the Cisco UCS 5100 Series blade chassis is maintained through the Cisco UCS 2100 or 2200 Series Fabric Extenders in each blade chassis. The Cisco UCS 2304 Fabric Extender is not supported. The Cisco UCS 6200 Series interconnects support out-of-band management through a dedicated 10/100/1000-Mbps Ethernet management port as well as in-band management. 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.
Optimization for Virtualization
For virtualized environments, the Cisco UCS 6200 Series supports Cisco virtualization-aware networking and Cisco Data Center Virtual Machine Fabric Extender (VM-FEX) architecture. VM-FEX allows the interconnects to provide policy-based virtual machine connectivity, with network properties moving with the virtual machine, and a consistent operational model for both physical and virtual environments.
Cisco UCS 6248UP 48-Port Fabric Interconnect
The Cisco UCS 6248UP 48-Port Fabric Interconnect (Figure 3) is a one-rack-unit (1RU) 10 Gigabit Ethernet, FCoE, and Fibre Channel switch offering up to 960 Gbps of throughput and up to 48 ports. The switch has thirty-two 1/10-Gbps fixed Ethernet, FCoE, and Fibre Channel ports and one expansion slot.
Cisco UCS 6296UP 96-Port Fabric Interconnect
The Cisco UCS 6296UP 96-Port Fabric Interconnect (Figure 4) is a 2RU 10 Gigabit Ethernet, FCoE, and native Fibre Channel switch offering up to 1920 Gbps of throughput and up to 96 ports. The switch has forty-eight 1/10-Gbps fixed Ethernet, FCoE, and Fibre Channel ports and three expansion slots.

Expansion Module Option for Cisco UCS 6200 Series Fabric Interconnects
The Cisco UCS 6200 Series supports an expansion module that can be used to increase the number of 10 Gigabit Ethernet, FCoE, and Fibre Channel ports (Figure 5). This unified port module provides up to 16 ports that can be configured for 10 Gigabit Ethernet, FCoE, and 1/2/4/8-Gbps native Fibre Channel using the SFP or SFP+[3] interface for transparent connectivity with existing Fibre Channel networks.
