Detailed Specifications

HPE 817721-B21 Ethernet 10Gb 2-Port 535FLR-T Adapter

Overview

The HPE 817721-B21 is a dual-port 10 Gigabit Ethernet adapter designed for server mezzanine/FLR-T slots, providing two RJ-45 10GBASE-T ports that deliver full line-rate performance per port while preserving standard PCIe slot real estate. It enables high-bandwidth uplinks over copper structured cabling (Cat6A/Cat7) and supports backward compatibility to 1 Gb/s. Advanced I/O features such as SR-IOV, tunnel offloads (VXLAN/NVGRE) and full virtualization awareness allow it to handle virtualized workloads, storage traffic, and converged infrastructure in rack servers. Ideal for environments where dual 10 Gb/s copper uplinks, efficient server I/O and simplified cabling are required, this adapter fits dense compute nodes, branch servers and rack deployments seamlessly.

Key Features

  • Two RJ-45 10 Gb/s (10GBASE-T) ports over standard copper cabling

  • Mezzanine/FLR-T form-factor designed for server integration

  • Support for SR-IOV, tunnel offloads, virtualization aware I/O

  • Backward compatible with 1 Gb/s links and existing cabling
