The Lenovo 00FE327 is a plug-in Layer 3 switch module that brings high-speed, low-latency interconnects to Flex System environments. Built around twenty-four 10 Gigabit Ethernet ports, it allows administrators to wire both external networks and internal compute nodes without adding stand-alone rack switches.
Ten SFP+ ports sit on the front panel and accept either 1 Gigabit or 10 Gigabit optical transceivers, giving you flexibility for campus links or data center uplinks. Inside the chassis, fourteen additional 10 Gigabit ports feed blades directly, streamlining east-west traffic and reducing cabling complexity.
A switching fabric rated at 480 Gbps keeps bandwidth headroom available for bursty workloads such as database replication, virtual machine migration, and storage traffic. Support for Converged Enhanced Ethernet and Data Center Bridging lets you transport storage protocols alongside standard IP without separate cabling.
From a management standpoint, the module fits neatly into existing toolsets. You can reach it through the dedicated Gigabit RJ-45 port or the front-panel mini-USB console, then authenticate sessions with RADIUS, TACACS+, or LDAP. These options simplify role-based access control in multi-tenant or enterprise environments.
IT teams running virtualized clusters, high-performance computing nodes, or mixed application blades will appreciate how the Si4091 consolidates switching inside the chassis, cuts latency, and reduces power draw compared with external top-of-rack designs. Deploy it where dense 10 GbE connectivity and straightforward management are priorities.
