HPEP26264-B21

Broadcom BCM57504 4-Port 10/25 GbE SFP28 Gigabit Ethernet Adapter- PCIe 4.0 ×16

The P26264-B21 adapter, featuring a Broadcom BCM57504 chipset, delivers four SFP28 ports capable of 10 GbE and 25 GbE data rates×a true performance upgrade for modern HPEProLiant Gen10+ and Gen11 servers. Engineered for low-latency, high-throughput environments, it's ideal for virtualization, SAN fabrics, cloud-native infrastructure, and RDMA applications. With support for advanced offload technologies and high link scalability, this card provides a future-ready solution for demanding enterprise networking.

Features

The adapter uses a PCI Express 4.0 ×16 slot (backward compatible with ×8), connecting to servers via four SFP28 interfaces. Each port supports both 10 GbE and 25 GbE speeds using compatible optics or DAC cables. By offloading

Advanced Options

critical network processing×such as Receive Side Scaling (RSS), TCP segmentation, and overlay tunneling (VXLAN/NVGRE, GENEVE)×it reduces CPU load while accelerating virtual workloads. Support for SR-IOV, DPDK, and RoCE v2 delivers efficient RDMA performance and enhanced VM networking. Elevated firmware security features×including digitally signed firmware and root-of-trust architecture×ensure reliability in enterprise deployments.
