Lenovo Flex System SI4093 Interconnect Module 10GBase-T | Blade Chassis

Build a cleaner, denser fabric inside Lenovo Flex System environments with the SI4093 System Interconnect Module. This expansion module is designed for data networking and optical network applications, giving infrastructure teams a practical way to connect blade chassis to upstream switching without adding unnecessary complexity. With 10GBase-T uplinks and support for both twisted pair and optical fiber media, it adapts to mixed infrastructure requirements. The module is engineered for Lenovo Flex System Enterprise Chassis models 8721 and 7893, making it a direct fit for organizations standardizing on Lenovo blade infrastructure. Its 10-port design and 14 expansion slots provide the connectivity profile expected in high-density chassis deployments, while SFP and SFP+ interface support helps align with existing fabric designs. For teams managing server consolidation, the SI4093 offers a measured upgrade path: more structured connectivity, fewer moving parts in the rack, and a module built to slot into an established Lenovo ecosystem. That makes it a strong choice when the goal is to improve fabric organization and preserve compatibility across the chassis lifecycle.
