Lenovo Flex System SI4091 10Gb Product Manual
                 |
Key featuresThe SI4091 interconnect module is considered particularly suited for the following customers:Customers who want simple 10 GbE network connectivity from the chassis to the upstream network,without the complexity of spanning tree and other advanced Layer 2 and Layer 3 features.Customers who want to manage physical compute node connectivity in the chassis by using the existingnetwork management tools.Customers who want to reduce total cost of ownership (TCO) and improve performance, whilemaintaining high levels of availability and security.Customers who want to minimize oversubscription, which can result in congestion and loss ofperformance.Customers who want to implement a converged infrastructure with NAS, iSCSI, or FCoE. For FCoEimplementations, the SI4091 passes through FCoE traffic upstream to other devices (such as theLenovo RackSwitch™ G8264CS) where the FC traffic is broken out.The SI4091 offers the following key features and benefits:Increased performanceWith the growth of virtualization and the evolution of cloud computing, many of today’s applicationsrequire low latency and high-bandwidth performance. The SI4091 supports sub-microsecond latencyand up to 480 Gbps throughput, while delivering full line rate performance.The SI4091 also offers increased security and performance advantage when configured in VLAN-awaremode; it does not force communications upstream into the network, which reduces latency andgenerates less network traffic.Simplified network infrastructureThe SI4091 simplifies the deployment of a converged LAN and SAN with support for the newestprotocols, including Data Center Bridging/Converged Enhanced Ethernet (DCB/CEE), which can be usedin a converged iSCSI, Fibre Channel over Ethernet (FCoE) or NAS environment.The default configuration of the SI4091 requires little or no management for most data centerenvironments, which eliminates the need to configure each device or individual ports and reduces thenumber of management points.Transparent networking The SI4091 is a transparent network device that is invisible to the upstreamnetwork and eliminates network administration concerns of Spanning Tree Protocol configuration andinteroperability, VLAN assignments, and avoidance of possible loops.By emulating a host NIC to the data center core, it accelerates the provisioning of virtual machines (VMs)by eliminating the need to configure the typical access switch parameters.Components and connectorsLenovo Flex System SI4091 10Gb System Interconnect Module 2 |
