HPE P42266-001

Broadcom BCM57504 4‑Port 10/25 GbE SFP28 Network Adapter – PCIe 4.0 x16

The P42266‑001, powered by the Broadcom BCM57504 chipset, is a high-performance Network Adapter delivering fourSFP28 ports capable of operating at 10 GbE or 25 GbE speeds. Designed for modern HPE ProLiant Gen10+ and Gen11 servers, it supports high-density, low-latency data center connectivity with robust protocol offloads and broad media compatibility. Whether deployed for virtualization, SAN fabrics, or high-throughput cloud workloads, this adapter enables scalable, secure, and efficient network performance in enterprise server environments.

Features

This adapter fits into a PCIe 4.0 x16 slot (backward-compatible with x8) and supports both fiber-optic and DAC link options via the SFP28 ports. Ideal for bandwidth-intensive deployments, it offers protocol acceleration including RDMA over Converged Ethernet (RoCE v2), SR-IOV, and DPDK support. With built-in

Advanced Options

features such as IPv4/IPv6 support, VXLAN/NVGRE encapsulation, VLAN tagging, and jumbo frame throughput, it significantly reduces CPU utilization and enhances VM networking performance. Compatible with the latest HPE Integrity and ProLiant platforms, it integrates into modern compute infrastructures requiring high-speed, low-latency connectivity.

Product Key Features

  • Four SFP28 ports supporting 10 GbE and 25 GbE speeds

  • PCI Express 4.0 x16 interface (auto-sensing x8 compatible)

  • Broadcom BCM57504 chipset with RoCE v2 and RDMA

  • Advanced virtualization support: SR-IOV, DPDK, NetQueue/VMQ

  • Offload features: RSS, TSO/LSO, VLAN tagging, jumbo frames

  • Secure firmware with signed BIOS/UEFI support

Reliability & Performance

Leveraging a next-generation Broadcom architecture, this adapter delivers line-rate throughput at minimal CPU overhead—ideal for virtualized and storage-rich server applications. Its support for hardware acceleration of tunneling and encapsulation protocols enables efficient packet processing, while DPDK and SR-IOV deliver consistent performance in containerized and multi-tenant environments. With a maximum power consumption around 15.2 W and certified thermal models, it supports sustained operation in dense rack environments. OEM firmware and integration into HPE server platforms ensure long-term firmware support, secure updates, and proven reliability.

Key Features :

  • 4 × SFP28 ports (10/25 GbE)

  • PCIe 4.0 x16 host interface (x8 compatible)

  • Broadcom BCM57504 with RoCE v2 support

  • Supports RSS, TSO, LSO, jumbo frames, VLAN tagging

  • SR‑IOV, DPDK, NetQueue/VMQ virtualization readiness

  • Secure firmware architecture and signed boot support
