Overview
The Cisco Nexus 5000 Series Switches are a family of low-latency, line-rate, 10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) switches for data center applications. The Cisco Nexus 2000 Series Fabric Extenders extend the internal switching fabric of the Cisco Nexus switches to remote devices to provide highly scalable, cost-effective, and simplified server-access connectivity.

The Cisco Nexus 5000 Series, part of the Cisco Nexus Family of data center-class switches, delivers an innovative architecture that simplifies data center transformation. These switches deliver high-performance, standards-based Ethernet and FCoE that enables the consolidation of LAN, SAN, and cluster network environments onto a single Unified Fabric. Backed by a broad group of industry-leading complementary technology vendors, the Cisco Nexus 5000 Series is designed to meet the challenges of next-generation data centers, including dense multisocket, multicore, virtual machine-optimized deployments, where infrastructure sprawl and increasingly demanding workloads are commonplace.

The Cisco Nexus 2000 Series Fabric Extenders comprise a new category of data center products that provides a universal server-access platform. Scaling across a multitude of Gigabit Ethernet, 10 Gigabit Ethernet, Unified Fabric, rack, and blade server environments, the Cisco Nexus 2000 Series Fabric Extenders are designed to simplify data center architecture and operations. Working in conjunction with Cisco Nexus switches, the Cisco Nexus 2000 Fabric Extenders architecture delivers a cost-effective and efficient way to support today's Gigabit Ethernet environments while allowing seamless migration to 10 Gigabit Ethernet, virtual machine-aware Unified Fabric technologies.

Cisco Nexus 5000 Series Hardware Features
  • The Cisco Nexus 5000 Series cut-through switching architecture supports line-rate 10 Gigabit Ethernet with low-latency and predictable performance on all ports. These switches also support 10/1 Gigabit Ethernet mode on a subset of the fixed ports to provide connectivity for Gigabit Ethernet attached servers and network devices.
  • The Cisco Nexus 5000 Series supports Fibre Channel over Ethernet that enables consolidation of LAN, SAN and cluster traffic onto a single, Unified Fabric, which greatly simplifies network infrastructure, increases flexibility and reduces costs. By connecting to existing Fibre Channel storage arrays, FCoE protects existing storage investments while simplifying in-rack cabling and reducing power and cooling overhead.
  • Cisco Nexus 5000 Series supports standards-based IEEE Data Center Bridging (DCB) capabilities that allows the switches to support multiple traffic classes-LAN, SAN, and cluster-over the same link, while retaining individual traffic treatment.
  • In addition to standard 10 Gigabit network interface cards (NICs), the Cisco Nexus 5000 Series supports standards-based Fibre Channel over Ethernet consolidated network adapters (CNAs) that combine Ethernet NICs and Fibre Channel host bus adapters (HBAs). These CNAs make the transition to a Unified Fabric transparent and consistent with existing practices, management software, and operating system drivers.
  • The Cisco Nexus 5000 Series is compatible with third-party integrated transceivers and Twinax cabling solution that delivers very low latency at a low cost, making the product line an excellent match for cluster environments.
  • The Cisco Nexus 5000 Series is designed for data center environments, with front-to-back cooling and network ports in the rear, bringing switching into close proximity to servers and making cable runs short and simple.
  • The Cisco Nexus 5000 Series is highly serviceable, with N+1 redundant, hot-pluggable power and fan modules. Its software is based on data center-class Cisco NX-OS Software for high reliability and ease of management.
  • Cisco Nexus 5000 Series Switches have built-in Cisco TrustSec in the hardware, enabling support for end-to-end security and role-based access control lists (RBACLs)-future.
  • The Cisco Nexus 5000 Series is built around two custom components: a unified crossbar fabric and a unified port controller application-specific integrated circuit (ASIC). Each Cisco Nexus 5000 Series Switch contains a single unified crossbar fabric ASIC and multiple unified port controllers to support fixed ports and expansion modules within the switch.
  • The unified port controller provides an interface between the unified crossbar fabric ASIC and the network media adapter and makes forwarding decisions for Ethernet, Fibre Channel, and FCoE frames. The ASIC supports the overall cut-through design of the switch by transmitting packets to the unified crossbar fabric before the entire payload has been received. The unified crossbar fabric ASIC is a single-stage, nonblocking crossbar fabric capable of meshing all ports at wire speed. The unified crossbar fabric offers superior performance by implementing quality-of-service (QoS) aware scheduling for unicast and multicast traffic. Moreover, the tight integration of the unified crossbar fabric with the unified port controllers helps ensure low-latency lossless fabric for ingress interfaces requesting access to egress interfaces.
