High performance computing (HPC) solutions have used InfiniBand networks to meet the needs of the most demanding set of applications and grand challenges. The QME7342 is a dual-port,40Gbps InfiniBand-to-PCI Express® Gen2 x8 Host Channel Adapter designed for the Dell® PowerEdge® Blade Server. The QME7342’s highly integrated design delivers unprecedented levels of performance, making it the ideal solution for HPC applications that rely on low latency, direct-memory access.

High Performance. Quad data rate (QDR) InfiniBand delivers 40Gbps per port (4 × 10Gbps), providing the necessary bandwidth for high-throughput applications. With the highest message rate and lowest latency of any InfiniBand adapter, the QME7342 provides superior HPC application performance.

Superior Scalability. QLogic’s TrueScale architecture delivers near-linear scalability. As additional compute resources are added to a cluster, latency remains low and the message rate scales with the size of the fabric,resulting in maximum usage of compute resources.

Enhanced Reliability. The QME7342’s advanced design does not need onboard firmware, which enhances its performance and reliability. The controller has ECC protection on all internal SRAMs, and parity checking on all internal buses. Equally important, the stateless design is inherently more resilient to adapter and fabric failures, as it minimizes its reliance on the connection state. Optional data scrambling maximizes data patterns, which in turn minimizes the bit-error rate.

Investment Protection. This fourth-generation product is compliant with IBTA version 1.2, ensuring interoperability with all other IBTA-compliant devices. In addition, support for the OpenFabrics community OFED and WinOF distributions ensures rapid adoption by major operating system vendors, system integrators, and independent hardware (IHV) and software (ISV) vendors.

Power Optimized. Maximum performance is delivered at the lowest power of any QDR-capable adapter: 6.2W typical and 9.5W maximum (estimate).

Environmentally Friendly. The QME7342 is RoHS 6 compliant, as well as antimony free and halogen free.
