Lenovo ThinkSystem DM Series 10Gb 4-Port Ethernet Card | SFP+ Enterprise

Sustain storage connectivity with four 10 GbE SFP+ ports in a compact plug-in card designed for optical fiber environments. The Lenovo ThinkSystem DM Series 10Gb 4 Port Ethernet Card gives storage platforms the bandwidth headroom needed for replication, client access, and clustered traffic without forcing a redesign of the network fabric. Built for Lenovo ThinkSystem DM Series systems, this adapter is a practical fit when port density matters and rack space is already committed. The SFP+ interface supports fiber-based deployments, making it easier to extend high-speed links across the data center while keeping signal integrity and cabling discipline under control. For teams standardizing on optical uplinks, the four-port layout reduces the need for additional adapters and helps preserve expansion capacity for other infrastructure priorities. This card is a strong choice for environments where storage performance, predictable connectivity, and vendor-aligned integration matter more than commodity pricing. It is designed to slot into the DM platform as part of a purpose-built storage architecture, helping maintain the network paths that keep workloads available and responsive.
