Introduction

The Cisco Nexus 4001I Switch Module is a blade switch solution for the BladeCenter H and HT chassis providing the server I/O solution required for high-performance, scale-out, virtualized, and non-virtualized x86 computing architectures. It is a line rate, extremely low-latency, non-blocking, Layer 2, 10 Gigabit Ethernet blade switch that is fully compliant with Fibre Channel over Ethernet (FCoE) and IEEE Data Center Bridging standards.

The Cisco Nexus 4001I enables a standards-based, high-performance Unified Fabric running over 10 Gigabit Ethernet in the blade server environment. This Unified Fabric enables consolidation of LAN traffic, storage traffic (IP-based such as iSCSI, NAS, and Fibre Channel SAN), and high-performance computing (HPC) traffic over a single 10 Gigabit Ethernet server network.

This offering works with BladeCenter Open Fabric Manager, providing all the benefits of I/O virtualization at 10 Gbps speed. Figure 1 shows the switch module.

Did you know?

Clients considering Fibre Channel over Ethernet as a fabric consolidation solution can implement a 10 Gigabit Ethernet infrastructure as the basis of the solution. The solution uses FCoE between the converged network adapter (CNA) in each server and a top-of-rack (TOR) switch such as the Cisco Nexus 5000 Series, with the Cisco Nexus 4001I blade switch at the access layer between them.

With this solution, clients gain most of the cost savings from the use of fewer adapters, cables, and switch ports. The FCoE connection between the CNA and the 4001I and 5000 Series switches will carry both Fibre Channel and Ethernet traffic on a single link. The Cisco Nexus 5000 Series switch will then separate LAN and Ethernet traffic to the Cisco Nexus 7000 Series switch upstream and SAN traffic to the Cisco MDS 9000 Family switch upstream.

Software Upgrade License for Cisco Nexus 4001I

The Cisco Nexus 4001I Switch Module is designed to support both 10 Gb Ethernet and Fibre Channel over Ethernet. Software Upgrade License for Cisco Nexus 4001I, part number 49Y9983, enables the switch to work in FCoE mode. When connected to a converged adapter in the server, this switch can route CEE packets to an upstream FCoE switch, which can then route the packets to the LAN or SAN.

Benefits

The benefits of the Cisco Nexus 4001I Switch Module include the following:

  • Lower total cost of operation (TCO): Deployment of Unified Fabric with the Nexus 4001I on the blade server access leverages a significant reduction in the number of switches, network interface cards (LAN and SAN), ports, optic modules, and cables. This consolidation of server access network elements significantly reduces the overall capital and operation costs of the data center network through the reduction of network elements to purchase, manage, power, and cool.
  • High performance: Nexus 4001I is a line rate, feature-rich, extremely low-latency switch capable of enabling server access migration from 1 GbE to 10 GbE to lossless 10 GbE, as well as, supporting the demanding latency requirements of High Performance Compute clusters or high-frequency trading applications.
  • Enhanced server virtualization: Utilizing Unified Fabric on the server access with Nexus 4001I provides uniform interfaces, simplified cabling, and consistent server access design required to leverage the advantages of automated virtual machine mobility. Using the Nexus 4001I in conjunction with the Nexus 1000V delivers the most operationally consistent and transparent server access design for virtual machine deployments, substantially reducing the overhead to configure, troubleshoot, and repair the server access link between the vNIC, virtual switch, and blade switch.
  • Increased resilience: The Nexus 4001I extends NX-OS to blade server access, providing a fault-tolerant network with a single modular operating system across the data center.
