HPE 562T PCIe 3.0 x4 10Gb Ethernet x 2 Network Adapter

The HPE 817738-B21 is a two-port 10 Gigabit Ethernet adapter designed for administrators who want higher network throughput without overhauling existing infrastructure. It fits into a PCIe 3.0 x4 slot and uses familiar RJ-45 connections, so you can keep the copper cabling already running through your racks and walls while moving from 1 Gb to 10 Gb speeds.

Built around the Intel X550-AT2 controller, the card manages traffic efficiently and offloads many packet-handling tasks. This reduces CPU overhead, which is especially valuable when your server juggles virtualization, database transactions, or heavy web workloads. Features such as jumbo frame support, SR-IOV, and small-packet offload further improve performance when packets fly in high-density environments.

The adapter ships with a low-profile bracket in the box, making it easy to install in space-constrained 1U or 2U chassis. Power draw is a modest 11.15 watts, and the card remains reliable from 41 to 140 degrees Fahrenheit. Compliance with RoHS 6/6 and WEEE standards helps you meet modern sustainability goals, while full IPv4 and IPv6 support keeps the adapter relevant as networks evolve.

Whether you run an e-commerce platform, a telecom application, or a high-performance computing cluster, the HPE 817738-B21 offers a straightforward path to 10 Gb connectivity and smoother server performance.
