QLogic QLE7140

QLogic QLE7140 the true high performance SDR 4x InfiniBand (IB) to PCI Express x8 Host Channel Adapter (HCA)

QLE7140 InfiniBand HCA

The InfiniPath InfiniBand adapter delivers industry-leading performance in a cluster interconnect, allowing organizations to gain maximum advantage and return from their investment in clustered systems.

Superior Application Performance

The InfiniPath adapter’s low latency and high message rates result in superior real-world application scalability across nearly all modeling and simulation applications.
Highest Effective Bandwidth and Message Rate

Because of its high messaging rate, the InfiniPath bandwidth curve rises faster than any other adapter. The InfiniPath PCI Express adapter delivers significantly more bandwidth at message sizes typical of real-world HPC applications and many enterprise applications. The InfiniPath InfiniBand adapter also delivers the highest effective bandwidth of any cluster interconnect because it achieves half its peak bandwidth (n1/2) 2 at a message size of just 385 bytes, the lowest in the industry.

Lowest MPI & TCP Latency

The InfiniPath industry-leading MPI pingpong latency of 1.6 microseconds2 (μs) is less than half of the latency of other InfiniBand adapters. Unlike other interconnects, its random-ring latency for up to 256 CPUs, as measured by the HPC Challenge Benchmark Suite, is nearly identical to its ping-pong latency, even as you increase the number of nodes.

Lowest CPU Utilization
The InfiniPath connectionless environment eliminates overhead that wastes valuable CPU cycles. It provides reliable data transmission without the vast resources required by connection-oriented adapters,thus increasing the efficiency of your clustered systems.

Built on Industry Standards
The InfiniPath adapter supports a rich combination of open standards to achieve industry-leading performance. The InfiniPath OpenIB software stack has been proven to be the highest performance implementation of the OpenIB Verbs layer, which yields both superior latency and bandwidth compared to other InfiniBand alternative.
