Dual‑Port 10 GbE RJ‑45 Network Adapter (PCIe 2.1 ×8)

The HPE 725052‑B21 is a high-performance dual-port 10 Gigabit Ethernet Network Adapter featuring two RJ‑45 copper ports with support for standard Cat6a/Cat7 cabling up to 100 m. It plugs into a PCI Express 2.1 ×8 slot (backwards compatible ×4), providing plug-and-play connectivity for HPE ProLiant and other servers. Perfect for virtualization, cloud compute, or high-throughput environments, it offers dependable, low‑latency networking with minimal setup.

Features

Built for enterprise environments, the adapter delivers full 10 Gbps throughput per port over 100 meters of twisted-pair cabling. The robust PCIe 2.1 ×8 interface ensures sustained bidirectional performance without bottlenecks. With support for jumbo frames, VLAN tagging, LACP link aggregation, and auto-negotiation, it integrates into modern network infrastructures with ease. Designed for server-grade deployments and validated on HPE platforms, the card is available in both full-height and low-profile configurations for flexibility in rack and blade chassis deployments

Advanced Options

Utilizing a Broadcom-based controller (QLogic BCMB) originally standardized across HP’s 10 GbE copper adapter lineup, the 725052‑B21 delivers enterprise-level performance with low latency and stable throughput. Each port sustains full 10 Gbps rates reliably on Cat6a or Cat7 cabling. The adapter
