InfiniBand Host Channel Adapter (HCA) cards deliver low-latency and high-bandwidth for performance-driven server and storage clustering applications in Enterprise Data Centers, High-Performance Computing, and Embedded environments. Clustered databases, parallelized applications, transactional services, and high-performance embedded I/O applications will potentially achieve significant performance improvements, helping reduce completion time and lower cost per operation. These HCAs simplify network deployment by consolidating clustering, communications, and management I/O, and providing enhanced performance in virtualized server environments.
