Key Features

Low-Latency, High-Bandwidth InfiniBand Connectivity

HPE HDR InfiniBand adapters deliver up to 200Gbps bandwidth and a sub-microsecond latency for demanding HPC workloads.

The HPE InfiniBand HDR100 adapters, combined with HDR switches and HDR cables, are aimed at simplified infrastructure by reducing the number of required switches for a given 100Gbps InfiniBand fabric.

HPE HDR InfiniBand adapters are supported on the HPE Apollo XL and HPE ProLiant DL Gen10 and Gen10 Plus servers.

Offloading Mechanisms

HPE HDR InfiniBand adapters include multiple offload engines that speed up communications by delivering a low CPU overhead for increasing throughput.

HPE HDR InfiniBand adapters support MPI tag matching and rendezvous offloads, along with adaptive routing on reliable transport.
