QLogic SDR 4x InfiniBand to PCI Express x8 Host Channel Adapter interface cards/adapter

PCI Express x8 to InfiniBand 4X Adapter The InfiniPath InfiniBand adapter delivers industry-leading performance
in a cluster interconnect, allowing organizations to
gain maximum advantage and return from their investment in
clustered systems.

The InfiniPath adapter yields the lowest latency, the highest
message rate and highest effective bandwidth of any cluster
interconnect available. As a result, organizations relying on
clustered systems for critical computing tasks will experience
a significant increase in productivity.

New applications being developed or deployed on very large
clusters now can avoid the bandwidth, latency, or message-rate
limitations imposed by traditional interconnects. By allowing
you to drive up the utilization of your computing infrastructure,
InfiniPath adapters increase the ROI of your computing assets.

Benefits:
-Increases cluster efficiency and application productivity.
-Provides superior application scaling to 1000s of CPUs.
-Enables faster application run times for faster time-to-solution.
-Increases utilization of computing infrastructure and increases ROI of computing assets.

Features:
-PCI Express x8 to InfiniBand 4X adapter.
-PCI half-height short form factor.
-1.6 μs one-way MPI latency through an InfiniBand switch1.
-954 MB/s uni-directional bandwidth1.
-385 byte n1/2 streaming message size (1 CPU core)1.
