The Lenovo Flex System Fabric SI4093 System Interconnect Module enables simplified integration of flex system into your networking infrastructure and provides the capability of building simple connectivity for points of delivery or clusters up to 252 nodes. The SI4093 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 SI4093 offers administrators a simplified deployment experience while maintaining the performance of intra-chassis connectivity.
