HPE 813661-B21

10Gb 2-Port 535T Ethernet Network Adapter

The HPE 813661-B21 Ethernet Network Adapter is a dual-port 10Gb BASE-T PCI Express 3.0 x8 card built with the Broadcom BCM57416 chipset. Designed for HPE ProLiant Gen10 servers, it delivers a cost-effective upgrade over legacy Gigabit Ethernet with advanced security and virtualization features.

Features

This adapter enables seamless integration into existing Cat6A-based LAN infrastructure while offering backward compatibility to 1GBASE-T environments×enabling straightforward upgrades without rewiring. The dual-port design delivers aggregate 20 Gbps bidirectional throughput, boosting server connectivity, virtualization density, and storage or compute traffic performance.

Advanced Options

Advanced offloads for RoCE v2, VXLAN, NVGRE, and DPDK minimize CPU overhead and accelerate network processing for demanding workloads such as live migration and NFV environments.The HPE BCM57416 adapter delivers robust enterprise features such as audit logs, hardware firmware authentication via Root of Trust, secure boot, and device-level firewall for enhanced resiliency against firmware tampering and attacks.

Product Key Features

• • Dual 10Gb BASE-T ports over Cat6A (up to 100 m)

  • PCIe 3.0 x8 interface for high-throughput

  • Broadcom BCM57416 network controller

  • Secure Boot, hardware root of trust, device-level firewall
