High Performance.

Quaddatarate(QDR)InfiniBanddelivers40Gbpsper

port (4×10Gbps), providing the necessary bandwidth for high-throughput
applications.  With the highest message rate and lowest latency of any
InfiniBand adapter, the QLE7340 provides superior HPC application
performance.

SuperiorScalability.

QLogic’sTrueScalearchitectureisdesignedtodeliver

near linear scalability.  As additional compute resources are added to a
cluster,latencyremainslowandthemessageratescaleswiththesizeof

Enhanced Reliability.

  The QLE7340’s advanced design does not need

onboard firmware or external memory, which enhances not only its
performance,butalsoreliability.TheASIChasECCprotectiononallinternal
