Overview
The HPE 877691-B21 is a high-end network adapter tailored for data-centre and high-performance computing (HPC) environments requiring dual 100 Gb/s uplinks. Each of its two QSFP28 ports supports 100 Gb/s InfiniBand EDR and 100-Gigabit Ethernet protocols, offering up to 200 Gb/s aggregate bandwidth across one adapter slot. With a PCI Express Gen3 ×16 host interface, it delivers line-rate throughput, ultra-low latency and large virtualization/cluster-fabric support for converged compute-storage and HPC nodes. It fits standard low-profile server slots certified by HPE and is built to handle dual high-speed links in a compact form-factor, ideal where cabling density and performance both matter.
