HPE ADP BCM57504 10G/25G SFP28 x4 (P42266-001)

For HPE ProLiant Gen10 Plus and Gen11 servers, the P42266-001 delivers four SFP28 ports capable of 10GbE or 25GbE each, with RoCE v2 and SR-IOV to accelerate virtualized and data-intensive workloads. Unlike standard 1GbE or 10GbE-only adapters, this OCP 3.0 card provides a future-ready 100Gbps aggregate throughput in a compact, energy-efficient form factor.

Highlights

• Quad-port SFP28 supporting 10/25GbE per port (100Gbps total)
• Broadcom BCM57504 controller with PCIe 4.0 x8 host interface
• OCP 3.0 Small Form Factor for HPE ProLiant Gen10 Plus/Gen11
• RoCE v2, SR-IOV, PXE boot, and jumbo frames (up to 9KB)
• Comprehensive OS support: Windows Server, RHEL, SLES, Ubuntu, VMware ESXi

In daily use

Deploy this adapter in hyper-converged infrastructure, software-defined storage, or high-frequency trading environments where low latency and high bandwidth are critical. The four independent SFP28 ports allow flexible network segmentation, link aggregation, or direct-attach top-of-rack connectivity. Hardware offloads for TCP/UDP/IP checksum, Large Send Offload (LSO), and Receive Side Scaling (RSS) reduce CPU overhead, freeing processor cycles for applications. Energy Efficient Ethernet (EEE) helps lower power consumption during periods of low network activity, while SR-IOV enables efficient sharing of the adapter among multiple virtual machines with near-native performance.
