Detailed Specifications

HPE P08440‑B21 Ethernet 10Gb 2‑Port 537FLR‑SFP+ Adapter

Overview

The HPE P08440‑B21 is a dual‑port 10‑Gigabit Ethernet adapter designed for HPE ProLiant Gen10 servers. It utilizes two SFP+ ports with full line‑rate 10 Gb/s performance per port and installs in a FlexibleLOM/FLR mezzanine slot, preserving standard PCIe slots for other uses. Tailored for virtualized, storage or compute‑dense workloads, this adapter supports advanced offloads such as SR‑IOV, VXLAN/NVGRE tunnel offload and DPDK to minimize CPU utilization and maximize network throughput. It is suitable for data‑centre servers where dual 10G uplinks and optical connectivity are required.

Key Features

  • Two 10 Gb/s SFP+ ports for fibre or DAC connectivity

  • FLR mezzanine form‑factor compatible with HPE Gen10 servers

  • Supports SR‑IOV, tunnel offload (VXLAN/NVGRE), DPDK

  • Low power consumption (~<14 W) and optimized for high‑density network I/O
