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-XDS simplifies network deployment by consolidating clustering, communications, storage, and management I/O and by providing enhanced performance in virtualized server environments. In addition to this outstanding InfiniBand capability, the AOC-IBH-XDS can be configured alternatively as 10-Gigabit Ethernet NIC when used with the Supermicro SBM-XEM-002 10-Gigabit pass-through module.
