Detailed Specifications
HPE 869573-001 Ethernet 10Gb 2-Port 521T Adapter
Overview
The HPE 869573-001 is a server-class network interface card (NIC) designed for engineers upgrading from 1 Gb to 10 Gb Ethernet in rack servers. It provides two RJ-45 10GBase-T ports and fits into a PCI Express slot in compatible HPE servers. It supports backward compatibility with 1 Gb infrastructure and utilizes existing CAT6A cabling where possible, helping simplify migrations. The card is well suited for virtualised servers, I/O-intensive applications and data-centre deployments where higher bandwidth and low latency are required. It integrates with HPE ProLiant server ecosystems and driver stacks, and supports advanced features such as RDMA over Converged Ethernet (RoCE) and tunnel offloads for virtualisation environments.
Key Features
Two 10 Gbps 10GBase-T RJ-45 ports
PCI Express 3.0 ×8 host interface
Backward compatible with 1 Gb infrastructure (auto-speed)
Supports RDMA, RoCE and virtualisation offload features
Uses standard CAT6A cabling for 10 GbBase-T migration
