QLogic’s announced on Monday that its QDR InfiniBand adapters have been chosen by IBM, Dell, HP and SGI for high-performance computing (HPC) connectivity.
Specifically, IBM will integrate QLogic’s 7300 Series 40Gb/sec. QDR (quad-data rate) InfiniBand host channel adapters (HCAs) into its IBM System X servers and the company’s iDataPlex solution. Dell will also integrate the HCAs with its PowerEdge servers and Precision workstations into HPC environments. Finally, HP will resell QLogic’s HCAs and its edge and director-level InfiniBand switches with both its ProLiant and BladeSystem c-Class servers and also offer them as part of the company’s HPC United Cluster portfolio. QLogic 7300 Series QDR InfiniBand-to-PCI Express 2 x8 host channel adapters are available in single- and dual-port models and have a unidirectional bandwidth of 3,400Mb/sec. As the size of clusters grow, additional compute nodes outfitted with QDR InfiniBand HCAs can be added to the cluster and the latency from the message passing interface (MPI) will remain flat. As for energy savings, the QLogic 7300 host channel adapters consume 3.8 watts in single-port and 4.8 watts in dual-port configurations and thus save power consumption in large HPC scale-outs. In addition, QLogic’s 7300 adapters have a small memory footprint and a connectionless operation that eliminates overhead that consumes host resources.
