Detailed Specifications
HPE 867705-001 Ethernet 10Gb 2-Port 521T Adapter
Overview
The HPE 867705-001 is a dual-port 10 Gigabit Ethernet server adapter designed for HPE ProLiant and similar enterprise servers. It uses a PCI Express 3.0 ×8 host interface and provides two BASE-T copper RJ-45 ports capable of 10 Gb/s link speed each. The adapter supports full line-rate throughput across both ports, offering up to 40 Gb/s bidirectional bandwidth under typical conditions. Equipped with advanced offload features such as SR-IOV, VXLAN/NVGRE, and RoCE v2, it is optimized for virtualized, storage-traffic and high-performance server environments. By leveraging existing copper cabling infrastructure, it offers a cost-effective 10 Gb upgrade path while freeing PCIe expansion slots for other uses.
