IBM selects QLogic to provide QDR InfiniBand switches for high performance environments

Integrates QLogic's 7300 series 40Gb/sec QDR InfiniBand host channel adapters into IBM's System x servers

By CBR Staff Writer

QLogic has expanded its OEM agreement with IBM for quad data rate (QDR) InfiniBand(R) switches. IBM has integrated QLogic’s 7300 Series 40Gb/sec QDR InfiniBand host channel adapters into its System x servers for high performance computing (HPC) applications. IBM is expected to offer QLogic QDR adapters as part of its new IBM System Cluster 1350.

Reportedly, the new QLogic QDR adapters will be offered with QLogic QDR switches as integrated HPC applications for molecular simulations, computational fluid dynamics, aeronautic design, geospatial imaging and computer-aided engineering.

QLogic claims that, based on its TrueScale ASIC platform for QDR InfiniBand, the 7300 Series delivers a higher messaging rate and lower scalable latency. This 7300 Series QDR InfiniBand-to-PCI Express (PCIe) Generation 2 x8 host channel adapters are available in single- and dual-port models.

According to QLogic, the 7300 Series advantages include, up to 30m messages/sec; low latency of 1.0 us point-to-point; bandwidth of 3400MBps unidirectional. The message passing interface latency remains low as additional compute resources are added to the cluster; and lightweight memory footprint at scale.

Jesse Parker, vice president and general manager of network solutions group at QLogic, said: HPC customers such as universities, government research labs and manufacturers have a growing demand for a cluster interconnect based upon open standards that scales more efficiently with the number of active cores in today’s multi-core compute environment.

“The addition of 40Gb/sec QDR network connectivity with QLogic’s unparalleled 30m messages-per-second and low scalable latency supports IBM’s high performance System x mission of increasing productivity, delivering the highest application performance and completing complex simulations faster than any other solution in the market today.
