Lenovo Flex System SI4091 10Gb System InterconnectModuleProduct GuideThe Lenovo® Flex System SI4091 10Gb System Interconnect Module enables simplified, low-cost integrationof Flex System™ into your networking infrastructure.The SI4091 requires no management for most data center environments, which eliminates the need toconfigure each networking device or individual ports, thus reducing the number of management points. Itprovides a low latency, loop-free interface that does not rely upon spanning tree protocols, which removes oneof the greatest deployment and management complexities of a traditional switch. The SI4091 offersadministrators a simplified deployment experience while maintaining the performance of intra-chassisconnectivity.The Flex System Fabric SI4091 System Interconnect Module is shown in the following figure.Figure 1. Lenovo Flex System Fabric SI4091 System Interconnect ModuleDid you know?The SI4091 provides transparent Flex System connectivity to your Cisco, Juniper, or other vendor network. TheSI4091 aggregates compute node ports by appearing as a simple pass-thru device. The upstream networksees a “large pipe” of server traffic coming to and from the chassis, with the main difference being that intra-chassis switching is supported. With the SI4091, a network administration team continues to use the samenetwork management tools that are deployed in the network to manage the connectivity from the physicalservers in the chassis to the upstream network.With support for Converged Enhanced Ethernet (CEE), the SI4091 can be used as an FCoE transit device. Italso is ideal for network-attached storage (NAS) and iSCSI environments.Lenovo Flex System SI4091 10Gb System Interconnect Module 1 |
