HPE 872726-H21 2-Port 40/50 Gb QSFP Adapter
Overview
The HPE 872726-H21 is a dual-port QSFP network adapter engineered for high-bandwidth server environments requiring both 40 Gb/s and 50 Gb/s link speeds. Its two QSFP ports support advanced connectivity including FDR InfiniBand and 50 Gb Ethernet, enabling dense uplinks from servers into storage or compute fabrics. With a FlexibleLOM or mezzanine slot form factor and support for PCIe x8/x16 host interfaces, the adapter fits into modern server architectures where high-throughput and low-latency I/O are critical. It is ideal for virtualised hosts, HPC clusters, and storage nodes deploying dual ultra-high-speed links in one adapter slot.
