The IBM 44V4645 is a high-performance 12X Channel Dual-Port SDR Host Channel Adapter (HCA) that provides superior connectivity for IBM servers within high-performance computing clusters or grid environments. Utilizing the GX+ interface, this adapter facilitates high-speed, low-latency InfiniBand connectivity, enabling efficient data transfer and communication between nodes. It supports Single Data Rate (SDR) InfiniBand, offering data transfer rates of up to 10 Gbps per port, and its dual-port configuration allows for increased bandwidth and redundancy, enhancing overall network performance and reliability. The adapter is designed for applications that demand high-speed, low-latency connections, such as computational simulation, data analysis, and high-performance storage access. It includes advanced features like RDMA (Remote Direct Memory Access), which allows for direct memory access between hosts without involving the CPU, significantly improving data throughput and reducing latency. The IBM 44V4645 is ideal for businesses and research institutions that require the highest levels of performance, scalability, and efficiency in their computing environments.
