HPE586444-001

NC550SFP Dual-Port 10 GbE Network Adapter(PCIe 2.0 ×8, SFP+)

The HPENC550SFP (586444-001) is a dual-port 10 Gigabit Ethernet adapter offering two SFP+ ports for DAC copper or SR fiber modules. Builton the Emulex/ServerEngines BE4210 controller and interfacing via PCIe 2.0 ×8 (with backwards compatibility to ×4), this card delivers full line-rate throughput with advanced offload features. Ideal for server uplinks, virtualization workloads, and data center networking, it's designed for HPEProLiant Gen6/Gen7 platforms and fits both full-height and low-profile systems.

Features

This adapter supports a broad range of network acceleration features×such as TCP/UDP checksum offload, LSO/TSO, NetQueue, jumbo frames (up to 9 KB), VLAN tagging, IPv4/IPv6, and NIC teaming (LACP). It enables high-performance data traffic with minimal CPU load and supports PXE boot and Wake-on-LAN. Compatible across HPEDL and ML servers (Gen6/Gen7), the card offers flexibility in both rack and tower deployments. Low power consumption (~10-15 W) and compliance with HPESea-of-Sensors thermal architecture ensure reliable operation in dense computing environments.

Advanced Options

Powered by a mature BE4210 (Emulex/ServerEngines) ASIC, the NC550SFP delivers reliable 10 Gbps performance per port with low latency and proven thermal resilience. The host interface ensures stable throughput, while offloading significantly reduces
