HPE817745-B21

Ethernet 10 Gb 2-Port FLR-T (X550-AT2) Network Adapter

The HPE817745-B21 Ethernet 10 Gb 2-Port FLR-T adapter (X550-AT2) is a high-performance FlexibleLOM network carddesigned for modern enterprise and virtualized workloads. Featuring dual RJ-45 10 GbE ports, it delivers up to 40 Gbps aggregate bandwidth using Cat 6A/7 cabling with backward compatibility to 1 GbE. Optimized for HPEProLiant Gen10 servers, this adapter elevates throughput while minimizing CPU utilization through efficient offloads. Ideal for virtualization, NFV, cloud computing, and high I/O density applications, it delivers stable, low-latency network performance aligned with today's data center demands.

Features

Built around the Intel X550-AT2 controller and using a PCIe 3.0 ×4 interface, this adapter integrates into ProLiant servers via the FLR-T form factor. Each port supports full line-rate 10 GbE throughput with minimal host impact, thanks to features like Single Root I/O Virtualization (SR-IOV), TCP/IP segmentation offload, tunnel offloads (VXLAN/NVGRE), and DPDK acceleration. It supports jumbo frames (up to 9 K MTU), IPv4/IPv6, PXE boot, and Wake-on-LAN functionality×making it a versatile choice for both new deployments and infrastructure upgrades. The adapter includes both low-profile and full-height brackets for flexible installation scenarios.

Advanced Options

Engineered for enterprise server environments, this adapter delivers unwavering throughput across both ports×even under intensive virtual and cluster workloads. The Intel X550-AT2 silicon and advanced offload capabilities reduce CPU overhead while maintaining low latency and network efficiency.
