NC522SFP Dual-Port 10 GbE Network Adapter Card - PCIe ×8, SFP+

The NC522SFP adapter (468332-B21) offers two high-throughput 10 GbE SFP+ ports in a PCIe ×8 card form factor, enabling full-duplex 20 Gb/s per port (40 Gb/s aggregate). Ideal for servers in virtualization, Adapter Carddata center, and storage environments, it supports both optical modules and direct-attach copper (DAC) cables. With features like jumbo frames, TCP/IP offloads, VLAN tagging, and NIC teaming, it ensures reduced CPU load, low latency, and stable performance across modern workloads.

Features

This Gen-2 PCI Express ×8 card features support for both full- and low-profile brackets, offering flexibility across server chassis. Compatible withAdapter CardHPProLiant G5-G7 servers, it connects via SFP+ for fiber or DAC cables and delivers enterprise-class reliability and integration. Using the Broadcom/NetXen-based chipset, this card offloads network processing functions×such as TCP segmentation offload (TSO), large send/receive offload, and checksum acceleration×to reduce server CPU utilization

Advanced Options

It supports jumbo frames up to 9KB MTU and Adapter Cardadvanced QoS with 802.1p tagging, ensuring performance in storage, backup, and virtualization settings Installation is plug-and-play, with driver support for major operating systems and network stack features. Designed for enterprise-use servers, the adapter fits into both standard and compact chassis, offering flexibility for dense rack or blade deployments. With validated HPcompatibility and firmware-level thermal control integration, it ensures energy-efficient operation and long-term stability even under sustained high-load usage.
