Detailed Specifications
HPE P18670-B21 SmartNIC 10/25 Gb 2-Port SFP28 Adapter
Overview
The HPE P18670-B21 is a server-grade Smart Network Interface Card (SmartNIC) designed for modern data-centre and cloud-scale server deployments requiring high-bandwidth uplinks and advanced offload capabilities. It offers two SFP28 ports capable of operating at either 10 Gb/s or 25 Gb/s each, enabling a flexible migration path from current 10 Gb infrastructure to emerging 25 Gb networks without swapping the adapter. The card supports full line-rate throughput, virtualization offloads such as SR-IOV and RDMA, and is optimized to reduce CPU load in virtualised and storage-intensive workloads. It fits into a low-profile server expansion slot (PCIe Gen4 ×8) or compatible mezzanine bay, conserving other expansion real-estate. Suitable for enterprise and hyper-scale servers, this SmartNIC enables dense, efficient network connectivity for compute nodes, storage servers or converged infrastructure when dual high-speed uplinks are required.
