Server.TheQME7342’shighlyintegrateddesign deliversunprecedented
levelsofperformance,makingittheidealsolutionforHPCapplicationsthat
relyonlowlatency,direct-memoryaccess.
HighPerformance.Quaddatarate(QDR)InfiniBanddelivers40Gbpsper
port(4×10Gbps),providingthenecessarybandwidthforhigh-throughput
applications. With thehighest message rate and lowest latencyof any
InfiniBand adapter, the QME7342 provides superior HPC application
performance.
Superior Scalability. QLogic’sTrueScalearchitecture delivers near-linear
scalability.Asadditionalcomputeresourcesareaddedtoacluster,latency
