This dual-port 10GbE SFP+ OCP3 adapter delivers 20 Gbps aggregate throughput with the Broadcom BCM57412 controller, engineered for network engineers and infrastructure architects demanding compact, high-performance connectivity in HPE ProLiant environments. The HPE P26256-B21 combines enterprise-grade reliability with modern virtualization capabilities, fitting HPE ProLiant Gen10 and Gen10 Plus servers equipped with OCP 3.0 slots.
The adapter operates over PCIe Gen3 x8 with full support for 10GBase-SR, 10GBase-LR, and 10GBase-CR Direct Attach Cable protocols, enabling flexible deployment across varied network topologies. Advanced offload engines including TCP Segmentation Offload, Large Receive Offload, and IPv4/IPv6 checksum offload reduce CPU overhead, while Single Root I/O Virtualization (SR-IOV) support enables efficient multi-tenant and cloud-native workloads. Integration with HPE iLO and HPE OneView streamlines lifecycle management across your infrastructure. Certified for Microsoft Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware ESXi, the HPE adapter meets CE, FCC, and RoHS regulatory requirements.
