Lenovo Flex System SI4091 10Gb System Interconnect Module

Brand: Lenovo
Model Number: FS-FSI4091-SIM

Management-Free Networking

The Lenovo® Flex System SI4091 10Gb System Interconnect Module enables simplified, low-cost integration of Flex System™ into your networking infrastructure.

The SI4091 requires no management for most data center environments, which eliminates the need to configure each networking device or individual ports, thus reducing the number of management points. It provides a low latency, loop-free interface that does not rely upon spanning tree protocols, which removes one of the greatest deployment and management complexities of a traditional switch. The SI4091 offers administrators a simplified deployment experience while maintaining the performance of intra-chassis connectivity.

Flex System SI4091 10Gb System Interconnect Module

Enables a simplified integration of Flex System into your existing networking infrastructure. The default configuration requires no management for most data center environments, which eliminates the need to configure each device or individual port and reduces the number of management points.

Performance Without Complexity

  • Increased performance
  • Simplified network infrastructure
  • Transparent networking

Simple Management

The Lenovo® Flex System™ SI4091 10 Gb System Interconnect Module enables a simplified integration of Flex System into your existing networking infrastructure. The loop-free default configuration of the SI4091 requires no management for most data center environments, eliminating the need to configure each device or individual ports and thus reducing the number of management points. The SI4091 offers administrators a simplified deployment experience while maintaining the performance of interchassis connectivity.

Easy Connectivity

The SI4091 is a low-touch, easy-to-deploy device that provides a transparent network interface connecting the upstream networking infrastructure to the Flex System chassis compute nodes. In addition, the SI4091 provides a clear division of roles and responsibilities between network and system administrators.

Reduced Cost

With the SI4091, clients can realize savings up to 69%1 in cabling and upstream switching costs and significant power reduction costs over the architecture associated with a traditional pass-thru device. This also increases return on investment by reducing the qualification cycle and increasing the speed of deployment.

1 Based on full chassis, redundant connectivity and list price of SI4091, EN4091, SFP+ SR transceivers on the module and the upstream switch plus average cost per port of a Cisco Nexus 5548. Minimum of 2 per SI4091 and upstream Cisco, plus 28 on EN4091 and upstream Cisco.
