HPE 561T dual-port 10Gb Ethernet adapter card, silver bracket

HPE Refurbished

HPE 716591-B21 561T 10Gb 2-port switch module

SKU CH-GWGB-RM269 MPN 716591-B21

A dual-port 10GbE adapter for ProLiant Gen8 servers using CAT6 cabling

  • Dual 10 GbE ports boost server throughput
  • Intel X540 controller delivers proven 10 GbE performance
  • Low-power design reduces Gen8 server energy draw
  • CAT6 UTP cabling simplifies 10GBASE-T deployment
  • VMDq and SR-IOV support accelerates virtualised workloads

HPE 561T 10Gb dual-port adapter for Gen8 servers

This refurbished HPE 716591-B21 module adds two 10GBASE-T ports to compatible ProLiant Gen8 rack, tower and scalable servers. It targets administrators who need 10 GbE connectivity over copper without replacing existing CAT6 or better cabling infrastructure.

Sustained throughput with Intel X540 controller

The onboard Intel Ethernet Controller X540 handles checksum offloading for TCP and UDP, MSI-X interrupts and Receive Side Scaling to distribute load across cores. These features keep latency low and CPU utilisation steady during continuous traffic rather than only in short bursts.

PCIe installation in Gen8 chassis slots

The card fits the dedicated adapter bays in supported Gen8 servers and uses standard CAT6 or better UTP patch leads. It will not operate in servers that lack the required Gen8 mezzanine or PCIe slot, and it does not support fibre or direct-attach copper cabling.
