Lenovo 00YK537 NX-E PCIe 25Gb 1-Port SFP28 network adapter.

The Lenovo 00YK537 is a PCIe network adapter featuring a single 25 Gigabit Ethernet port with SFP28 connectivity. This high-performance adapter is designed for server installations requiring low-latency, high-bandwidth network connections in modern datacentre environments.

This adapter is part of Lenovo’s NX-E series of network interface cards, engineered for use in ThinkSystem and compatible Lenovo server platforms. The SFP28 interface supports 25GbE connectivity, enabling efficient east-west traffic within datacentres and supporting software-defined networking architectures.

The 25GbE standard provides a cost-effective upgrade path from 10GbE infrastructure, offering 2.5 times the bandwidth without requiring a full transition to 40GbE or 100GbE. This makes it well-suited for hyperconverged infrastructure, virtualisation workloads, and high-performance computing applications.
