High Performance
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
QLE7300 series provides superior HPC application performance.

QLE7300 series provides superior HPC application performance.
Superior Scalability
QLogic’s TrueScale architecture is designed to deliver near linear
application 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 QLE7300 series’ 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 1.2.1 specification, ensuring interoperability
with all other IBTA compliant devices. In addition, support for OpenFabrics
Enterprise Distribution (OFED) releases ensures rapid adoption by major
operating system vendors, system integrators, and independent hardware
(IHV) and software (ISV) vendors.
