QLogic QLE7340 Single-Port 40 Gbps QDR InfiniBand Host Channel Adapter

High-performance computing (HPC) solutions have used InfiniBand networks to meet the needs of the most demanding sets of applications and grand challenges. The QLE7340 is a single-port 40 Gbps InfiniBand PCI Express Gen2 x8 host channel adapter (HCA). It is a highly integrated design that delivers a high message rate and low latency, making it the ideal solution for HPC applications.

Figure 1 shows the QLogic QLE7340 single-port 4X QDR IB PCIe 2.0 X8 host channel adapter.

Features and benefits

The QLogic QLE7340 HCA has the following summary of features and specifications:

• 40 Gbps InfiniBand interface (40/20/10 Gbps auto-negotiation)
• 3400 MBps unidirectional throughput
• Approximately 30 million messages processed per second (non-coalesced)
• Approximately 1.0 microsecond latency that remains low as the fabric is scaled
• Multiple virtual lanes (VLs) for unique quality of service (QoS) levels per lane over the same physical port
• TrueScale architecture, with MSI-X interrupt handling, optimized for multi-core compute nodes
• Operates without external memory
• Optional data scrambling in InfiniBand link
• Complies with InfiniBand Trade Association 1.2 standard
• Supports OpenFabrics Alliance (OFED) software distributions, WinOF support planned for 1Q/2010

Key benefits of the QLogic QLE7340 HCA are:

• High performance: Quad Data Rate (QDR) InfiniBand (IB) delivers 40 Gbps per port (4x10 Gbps), providing the necessary bandwidth for high-throughput applications. With one of the highest message rates and lowest latencies of any IB adapter, the QLE7340 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 QLE7340's advanced design does not need onboard firmware or external memory, which enhances not only its performance, but also reliability. The application-specific integrated circuit (ASIC) has ECC protection on all internal static random access memories (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 vendors (IHVs) and independent software vendors (ISVs).
• Power optimized: Maximum performance is delivered at the lowest power (3.8 W typically and 6.7 W maximum) of any QDR-capable adapter.
• Environmentally friendly: The QLE7340 is RoHS 6 compliant as well as antimony free and halogen free.
