HPE 872726-H21 100 Gb/s 2‑Port QSFP28 Adapter

Overview

The HPE 872726-H21 is a dual‑port server adapter delivering 100 Gb/s Ethernet and 100 Gb/s EDR InfiniBand connectivity via QSFP28 interfaces. Designed for high-performance computing and data‑centre servers, it fits a PCI Express Gen3 ×16 slot to provide full-line-rate throughput on both ports. The adapter supports advanced offloads such as SR‑IOV with up to 256 virtual functions, VXLAN/NVGRE tunnel offloading, RoCE (RDMA over Converged Ethernet), and jumbo frames up to 9.6 KB. It is ideal for clustered, virtualised, or storage-intensive workloads, enabling dual high-speed uplinks from a single slot. The compact form-factor and validated compatibility with HPE ProLiant and XL servers ensure reliable deployment in dense server environments.
