Abstract

High-Performance Computing (HPC) and Big Data applications demand the best performance possible with the lowest latency and the greatest throughput. Traditional LAN switch architectures add control plane and other overhead that negatively impact performance

Lightfleet Corporation commissioned Tolly to evaluate the end-to-end latency, throughput and fabric power consumption of its Lightfleet Data Distribution System (DDS). DDS consists of the Lightfleet Data Distribution Module (DDM) which provides the fabric and the Lightfleet host bus adapter (HBA) and related software for the end-station. This was compared to a traditional switch as represented by the Arista 7150 running 10GbE in conjunction with Solarflare 7122 10GbE network interface cards (NIC) and related software for the end-station.

Tests showed that the Lightfleet solution delivered higher throughput, lower latency and lower power consumption than the Arista/Solarflare solution.
