Intel 100HFA018LS network card 56 Gbps PCIe 3.0 x8 low profile

Intel 100 Series Omni-Path Adapter

The Intel 100HFA018LS is a low-profile network interface card built for high-performance compute clusters. It connects through a PCI Express 3.0 x8 slot and provides a single QSFP28 port rated for 56 Gbps fabric speed. The card measures 6.60 inches by 2.713 inches and weighs 0.53 lb. It carries RoHS and REACH environmental certifications.

Suited for HPC clusters needing fabric optimisation

This adapter targets installations that require end-to-end fabric optimisation, high MPI message rates and built-in congestion control with QoS. The single-port design and low-profile bracket suit dense server chassis where space is limited. Buyers needing multiple ports per card or a different host interface should evaluate alternative form factors.

Single-port headroom at 56 Gbps

The single QSFP28 port delivers 56 Gbps of bandwidth for latency-sensitive MPI traffic and storage workloads. Congestion control and QoS features help sustain throughput under heavy load. Capacity is bounded by the single port and the PCIe 3.0 x8 host link, so configurations demanding higher aggregate bandwidth will require additional adapters.
