Product Overview

The Cisco Nexus 5000 Series is a family of top-of-rack switches for the data center. The Cisco Nexus
5000 Series offers high-speed Ethernet switching and supports Fibre Channel over Ethernet (FCoE) to
provide data center I/O consolidation (IOC).
The Nexus 5010 switch provides 20 fixed Ethernet ports in a 1 RU switch and the Nexus 5020 switch
provides 40 fixed Ethernet ports in a 2 RU switch. Optional expansion modules provide native Fibre
Channel ports and additional Ethernet ports.

New Technologies in the Cisco Nexus 5000 Series

Cisco Nexus 5000 Series switches introduce several new technologies, which are described in the
following sections:
•

Fibre Channel over Ethernet

Fibre Channel over Ethernet (FCoE) provides a method of encapsulating Fibre Channel traffic over a
physical Ethernet link. FCoE frames use a unique Ethertype so that FCoE traffic and standard Ethernet
traffic can be carried on the same link.
Fibre Channel traffic requires a lossless transport layer. Native Fibre Channel implements lossless
service using a buffer-to-buffer credit system. For FCoE traffic, the Ethernet link must provide lossless
service.
Ethernet links on Cisco Nexus 5000 Series switches provide two mechanisms to ensure lossless transport
for FCoE traffic: link-level flow control and priority flow control.

    I/O consolidation (IOC). The Nexus 5010 switch provides 20 fixed Ethernet ports in a 1 RU switch and the Nexus 5020 switch provides 40 fixed Ethernet ports in a 2 RU switch. Optional expansion modules provide native Fibre Channel ports and additional Ethernet ports.
  • Page 2 Fibre Channel operational model is maintained. FCoE network management and configuration is similar to a native Fibre Channel network. Cisco Nexus 5000 Series switches use FCoE to carry Fibre Channel and Ethernet traffic on the same physical Ethernet connection between the switch and the server. At the server, the connection terminates to a converged network adapter (CNA) .

    Management Interfaces, page 1-4 Chassis The Nexus 5010 switch is a 1 RU chassis and the Nexus 5020 switch is a 2 RU chassis designed for rack mounting. The chassis supports redundant fans and power supplies. The Cisco Nexus 5000 Series switching fabric is low latency, nonblocking and supports Ethernet frame sizes from 64 to 9216 bytes.

    Fibre Channel ports are optional on the Cisco Nexus 5000 Series switch. When using expansion modules up to eight Fibre Channel ports are available on the Nexus 5010 switch and up to sixteen Fibre Channel ports are available on the Nexus 5020 switch.

    • Licensing Cisco Nexus 5000 Series switches are shipped with the licenses installed. The switch provides commands to manage the licenses and install additional licenses. The Cisco Nexus 5000 Series switch provides quality of service (QoS) capabilities such as traffic prioritization and bandwidth allocation on egress interfaces.

This feature is a step toward autonomous system operation, which enables networking devices to inform IT when a problem occurs and helps to ensure that the problem is resolved quickly.

    SNMP—SNMP allows you to configure switches using Management Information Bases (MIBs). Configuring with Cisco MDS Fabric Manager You can configure Cisco Nexus 5000 Series switches using the Fabric Manager client, which runs on a local PC and uses the Fabric Manager server.

    In this example, the blade server rack incorporates blade switches that support 10-Gigabit Ethernet uplinks to the Cisco Nexus 5000 Series switch. The blade switches do not support FCoE, so there is no FCoE traffic and no Fibre Channel ports on the Cisco Nexus 5000 Series switch.

  • Page 9: Ioc Topology

    Nexus Switch The Cisco Nexus 5000 Series switch connects to the server ports using FCoE. Ports on the server require converged network adapters. For redundancy, each server connects to both switches. Dual-port CNA adapters can be used for this purpose. The CNA is configured in active-passive mode, and the server needs to support server-based failover.
