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.
