HPE P08446-B21
Ethernet 10 Gb 2‑Port 524SFP+ Gigabit Ethernet Adapter
The HPE P08446‑B21—also known as the 524SFP+ dual-port adapter—is a high-performance 10 Gigabit Ethernet card providing two SFP+ ports via optical interfaces. Powered by the Mellanox ConnectX‑4 Lx controller (QL41401‑A2G), it delivers full line-rate throughput while minimizing CPU load with advanced offloads. Ideal for virtualization, cloud workloads, and high-speed storage, it brings reliable, low-latency connectivity to HPE ProLiant Gen10 servers and beyond
Features
This PCIe 3.0 ×8 plug-in adapter employs two SFP+ ports to support optical fiber connections, offering backward compatibility with 1/2.5/5/10 GbE via auto-negotiation. Key virtual networking protocols such as VXLAN, NVGRE, GENEVE, and RDMA (RoCE, RoCEv2, iWARP) are supported, enhancing VM migration and storage offloads. The adapter also supports SR‑IOV, RSS, VMQ, and DPDK for optimized multi-tenant and cloud performance
Advanced Options
Engineered for dense virtualization and high-throughput workloads, this adapter delivers sustained 10 Gbps on each port with ultra-low latency. The ConnectX‑4 Lx chipset offloads many CPU tasks, improving overall VM performance and host efficiency.
