QLE7342

High Performance Computing (HPC) solutions have used InfiniBand (IB) networks to meet the needs of the most demanding set of applications and grand challenges. The

QLE7342 is a dual-port 40Gbps InfiniBand PCI Express^®

 

Gen2 x8 Host Channel Adapter (HCA). It is a highly integrated design that 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) IB delivers 40Gbps per port (4x10Gbps), providing the necessary bandwidth for high-throughput applications. With the highest message rate and lowest latency of any IB adapter, the QLE7342 provides superior HPC application performance.

Superior Scalability :

QLogic’s TrueScale architecture is designed to deliver 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 utilization of compute resources.

Enhanced Reliability :

The QLE7342’s advanced design does not need onboard firmware or external memory, which enhances not only its performance, but also reliability. The ASIC 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 provides a mechanism to optimize data patterns, which in turn minimizes the bit-error rate.

Investment Protection :

This fourth generation product is compliant with the InfiniBand Trade Association (IBTA) version 1.2 specification, 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, 4.8W typical and 8.1W maximum, of any QDR-capable adapter.

 

Environmentally Friendly:

The QLE7342 is RoHS 6 compliant as well as antimony free and halogen free.
