HP 656596-B21

(530T) Dual‑Port 10 GbE Ethernet Network Adapter

The HP 656596‑B21 (530T) is a dual‑port 10 GbE copper adapter designed for high-performance networking over standard RJ‑45 connections. It offers 10 Gb connectivity via familiar Cat6A cabling and integrates smoothly with HP ProLiant Gen8/Gen9/Gen10 servers, making it perfect for virtualization, HPC, and scalable IT environments.

Features

Featuring the Broadcom BCM57810S chipset, this adapter delivers up to 20 Gbps per port (40 Gbps aggregate) with full duplex line‑rate capability. It supports auto‑negotiation at 1 Gbps or 10 Gbps and distances up to 100 meters over Cat6A cabling—or up to ~30 m over Cat6 UTP—offering cost‑effective, high-speed server connectivity. The PCIe 2.0 x8 interface ensures broad compatibility across HP servers and industry platforms

Advanced Options

With robust support for SR‑IOV, NPAR, jumbo frames, RSS, MSI‑X, and virtual machine queueing, it improves application performance and reduces CPU load in hypervisor environments. The adapter enables features like PXE boot, IEEE 1588 PTP timing, TCP offload engine (TOE), and compatibility with VMware NetQueue and Microsoft VMQ

Product Key Features

    •  Dual 10GBASE‑T RJ‑45 ports delivering full line‑rate 10 Gbps per port

    •  Powered by Broadcom BCM57810S chipset for proven reliability and performance

    •  PCI Express 2.0 x8 interface for seamless integration into servers

    •  Supports enterprise-grade features: SR‑IOV, NPAR, jumbo frames, VLAN tagging, RSS, MSI‑X, PXE boot

    •  HP Sea of Sensors 3D thermal optimization for energy-efficient operation

    •  Ideal upgrade path for virtualized servers and cloud environments

Reliability & Performance

Engineered for enterprise-grade reliability, the 530T adapter includes HP Sea of Sensors technology to proactively manage heat and enhance energy efficiency. The card supports field-replaceable components and maintains consistent performance in dense server racks. Offloading tasks like checksum, segmentation, and virtualization deliver efficient throughput and low latency even under heavy load
