Single-Port, Low Latency InfiniBand Adapter Cards For SuperBlade

AOC-IBH-002 This InfiniBand mezzanine card for the SuperBlade delivers low-latency and high-bandwidth for performance-driven server and storage clustering applications in Enterprise Data Centers, High-Performance Computing, and Embedded environments. Clustered data bases, parallelized applications, transactional services and high-performance embedded I/O applications will achieve significant performance improvements resulting in reduced completion time and lower cost per operation. AOC-IBH-002 simplifies network deployment by consolidating clustering, communications, storage, and management I/O and by providing enhanced performance in virtualized server environments.
