Detailed Specifications

HPE 656596-B21 – Ethernet 10Gb 2‑Port 530T Adapter

Overview :

The HPE 656596-B21 is a dual‑port 10GBASE‑T network adapter designed for data centre and virtualised server environments. Engineers deploying this adapter use it to provide high‑speed 10 Gb/s copper Ethernet connectivity over CAT6A UTP cabling, reducing network bottlenecks in dense compute racks. The adapter supports full line‑rate traffic on both ports and offers features such as jumbo frame support, NIC teaming and hardware offloads for aggregated server traffic. It is typically installed in rack or tower servers, such as HPE ProLiant Gen8/Gen9 systems, and is suitable for campus aggregation or edge server network uplinks. Integration with HPE server management frameworks like Sea of Sensors helps maintain thermal and power efficiency under heavy network loads.

Key Features :

  • Dual RJ‑45 ports with 10GBASE‑T up to 100 m cable length

  • PCI Express 2.0 x8 form factor with full‑height and low‑profile support

  • Full line‑rate throughput across both ports (~40 Gb/s aggregate)

  • Network virtualization support including SR‑IOV, VMQ, NPAR

  • Hardware acceleration of TCP/IP offload, jumbo frames and RSS
