Lenovo Flex System SI4091 10Gb System Interconnect Module

The Flex System SI4091 10Gb System Interconnect Module enables simplified integration of Flex System products into your existing networking infrastructure. The SI4091 requires no management for most data center environments, so it can reduce the number of management points and eliminate the need to configure each networking device or individual port. This module provides a low latency, loop-free interface that does not rely upon spanning tree protocols, so it also eliminates one of the greatest deployment and management complexities of a traditional switch. The SI4091 offers administrators a simplified deployment experience while it maintains the performance of intra-chassis connectivity.

The SI4091 is a cost effective entry level layer 2 device that delivers 10Gb throughput with minimal configuration and little ongoing maintenance. The SI4091 provides 24 ports that are arranged as fourteen 10Gb internal ports and ten 10Gb small-form-factor pluggable plus (SFP+) external ports.

Additional capabilities, features, and upgrades for this module include the following:
  • Supports Ethernet, iSCSI, and Fibre Channel over Ethernet (FCoE).
  • Provides server-to-server communication at layer 2 and can support autonegotiation to 1Gb.
  • SFP+ ports allow for 10Gb or 1Gb uplink speeds
