About the Lenovo ThinkSystem 25GbE SFP28 2-Port PCIe Ethernet Adapter

The Lenovo ThinkSystem 25GbE SFP28 2-Port PCIe Ethernet Adapter delivers wire-speed 25 Gigabit Ethernet connectivity per port, enabling aggregated 50 Gbps throughput for demanding server workloads. Deployed extensively in cloud and telecom infrastructure since Q3 2022, this adapter supports modern server fabric architectures that require low-latency, high-bandwidth interconnect between compute nodes and top-of-rack switching infrastructure. The SFP28 optics interface provides flexibility for both short-reach multimode and long-reach single-mode fiber deployments across distributed data centers.

Architected for PCIe Gen3 x8 or Gen4 x4 integration, the adapter maintains non-blocking performance and efficient host CPU utilization through advanced DMA and queue pair management. Built-in support for RDMA, DCB, and congestion management protocols accelerates emerging workloads including distributed machine learning, real-time analytics, and high-frequency trading platforms. Extensive validation across ThinkSystem server platforms ensures compatibility and production reliability at scale.

Ideal for

  • Cloud infrastructure provider leaf-spine fabric upgrades supporting 25G per-server egress capacity
  • Telecom operator data center deployments requiring high port density and multi-tenant traffic isolation via DCB
  • High-performance computing clusters with RDMA-accelerated collective communications and checkpoint operations
  • Real-time financial and trading infrastructure requiring ultra-low packet latency and jitter characteristics
  • Distributed database and NoSQL cluster deployments with bandwidth-intensive replication and consensus protocols
  • Machine learning training farms requiring sustained multi-gigabit throughput for distributed parameter synchronization
