Product Description
The HP 431039-B21 is an InfiniBand Host Channel Adapter (HCA) that provides a high-performance interconnect solution for servers. It utilizes the PCI Express (PCIe) bus for integration into server systems, typically requiring a PCIe x8 slot to accommodate the bandwidth of a 4X InfiniBand connection. InfiniBand technology is specifically engineered for applications demanding extremely high bandwidth and very low latency, such as High-Performance Computing (HPC) clusters, large-scale data analytics, and high-frequency trading platforms. This adapter supports DDR (Double Data Rate) InfiniBand, which offers significantly higher throughput than previous generations. The adapter features a single 4X InfiniBand port, usually equipped with a QSFP connector, designed to connect directly to an InfiniBand switch or another HCA. The 4X designation refers to the number of lanes used for data transmission, providing substantial aggregate bandwidth (e.g., approximately 20 Gbps per lane for DDR, totaling around 80 Gbps). This makes it ideal for high-speed inter-server communication and direct storage access in demanding environments.
