HPE P26264-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 HPE ProLiant 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.
