QLogic QLE7340光纤通道卡
一个的QDR4X InfiniBand的外部端口; PCI Express2个x8主机总线接口;薄型的外形PCI Express适配器(括号内提供的2U和3U);数据传输速率,40,20,或10 Gbps(自动协商);符合PCI热插拔规范1.0,PCI总线电源管理接口规范1.2;外部端口,支持四通道小型可插拔


QLogic QLE7340 HCA has the following specifications:
  • One QDR 4X InfiniBand external port
  • PCI Express Gen 2 x8 host bus interface
  • Low-profile form-factor PCI Express adapter (2U and 3U brackets supplied)
  • Data rates of 40, 20, or 10 Gbps (auto-negotiated)
  • Compliant with PCI Hot Plug Specification 1.0, PCI Bus Power Management Interface Specification 1.2
  • Virtual lanes: configurable for one, two, four, or eight virtual lanes: 2 KB MTU or 4 KB MTU (single IB port)
  • MTU: All standard IB MTUs including 4 KB
  • External port supports Quad Small Form Factor Pluggable

Operating environment

The adapter is supported in this environment:
  • Temperature:
    • Operating: 0° to 55°C (estimated)
    • Storage: -40° to 70°C (estimated)
  • Relative humidity: 10% to 95% (non-condensing)
  • Power consumption: typical 3.8 W, maximum 6.7 W (estimated)

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.
