HPE P08451-B21 Marvell 10/25GbE 2-Port SFP28 Adapter

Overview

The HPE P08451-B21 is a network interface card (NIC) featuring two 10/25 GbE SFP28 ports, based on Marvell FastLinQ technology. It is designed for high-throughput, low-latency workloads in virtualized or cloud-native data-center environments. The adapter uses a PCI Express Gen4 x8 interface and supports advanced offload protocols such as RoCE v2 and SR-IOV, reducing CPU load while maximizing I/O efficiency. Its compact, low-profile form factor makes it well-suited for modern HPE ProLiant and Apollo Gen10 / Gen11 servers.

Key Features

  • Two 10/25 GbE SFP28 ports for flexible connectivity

  • Marvell FastLinQ controller with offload support

  • PCI Express 4.0 ×8 for high I/O bandwidth

  • RoCE v2 and TCP offloads reduce application latency

  • Virtualization-ready: SR-IOV and VMware NetQueue
