HPE 867331-B21

Ethernet 10 Gb 2‑Port 522FLR‑T Network Adapter

The HPE  867331‑B21 is a dual‑port 10 Gigabit Ethernet Network Adapter in the 522FLR‑T FlexibleLOM form factor, designed for HPE ProLiant Gen10 and Gen10+ servers. With its two RJ‑45 ports, this adapter delivers high-bandwidth copper connectivity ideal for virtualization, large-scale compute, and network/storage convergence deployments. It consolidates network and storage traffic over a single link as a converged Network Adapter (CNA), reducing cabling complexity and simplifying infrastructure design. Supporting PCIe v2.0 x8 interface in the FlexibleLOM position, it's optimized for data centers and enterprises seeking cost-effective 10 Gb upgrade paths without adding mezzanine cards. With low power consumption (~8.4 W typical, 9.7 W max) and wide deployment support, it's a versatile choice for modern server networking needs.

Features

The adapter installs into the FlexibleLOM slot of compatible ProLiant servers, freeing up PCIe slots while offering two copper 10 Gb ports via standard RJ‑45 connectors. This simplifies deployment in existing Cat6a infrastructure and enables backward compatibility with 1 Gb switches through auto-negotiation. Operating at 10 Gb per port, the card supports both networking and storage protocols (such as iSCSI or FCoE), enabling streamlined data center designs without additional Host Bus Adapters. The converged network functionality reduces hardware footprint and operational overhead by combining LAN and SAN roles over a single physical link

Advanced Options

With a PCI Express v2.0 x8 interface, the card delivers full throughput without the latency or power overhead of PCIe x16 adapters. The power profile is modest—just 8.4 W typical and under 10 W peak—supporting efficient thermal operation inside dense server chassis. Compatible with HPE ProLiant Gen10 and Gen10+ platforms (e.g., DL360 G10/G10+ and DL380 G10/G10+), this adapter is ideal for scalable virtualization, storage consolidation, and I/O-intensive workloads in enterprise datacenters Engineered for reliability and consistent performance in enterprise environments, this adapter delivers stable 10 Gb throughput across both ports. The copper RJ‑45 connectors simplify integration, support auto-negotiation with 1 Gb switches, and allow using existing infrastructure. Hardware offload support for storage and networking protocols reduces host CPU utilization, especially in converged workloads such as VMware, iSCSI, or data analytics environments. The card’s compact FlexibleLOM design offers high-density installation without occupying PCIe slots, preserving server expansion flexibility.
