PCIe Dual-Port InfiniBand Adapter QLE7342

Mfg. Part Number:
QLogic QLE7342-CK, retail kit.
RoHS compliant

Features & Benefits:
High Performance Computing (HPC) solutions have used InfiniBand networks to meet the needs of the most demanding set of applications and grand challenges. The QLE7342 is a dual-port 40Gbps (QDR) "InfiniBand to PCI-Express®" host bus Adapter  adapter. 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.
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 QLE7342 provides superior HPC application performance.
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.
