HPE 817745-B21
Ethernet 10 Gb 2‑Port FLR‑T (X550‑AT2) Network Adapter
The HPE 817745‑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 HPE ProLiant 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.
