IBM 59Y1890 QLE7340 1 x Port 4X QDR Infiniband PCI-Express X8 Host Channel Adapter

Product Description

The IBM 59Y1890 is a high-performance Host Channel Adapter (HCA) based on the QLE7340 chipset, designed to facilitate extremely fast and low-latency communication between servers. This adapter features a single 4X QDR InfiniBand port, which is a standard for high-performance interconnects used in demanding computing environments. InfiniBand technology is optimized for parallel processing and data-intensive applications, offering superior bandwidth and reduced latency compared to traditional Ethernet or Fibre Channel networks. Connecting via a PCI-Express X8 interface, the 59Y1890 ensures a high-bandwidth connection to the server's motherboard, allowing the InfiniBand port to operate at its full potential. The QDR (Quad Data Rate) specification signifies a data transfer rate of up to 40 Gbps per lane, and with 4 lanes, this adapter can achieve significant throughput. This makes it an essential component for High-Performance Computing (HPC) clusters, large-scale data analytics platforms, and other applications where rapid data exchange between nodes is critical. This adapter enables efficient direct memory access (DMA) between connected servers, bypassing the CPU for data transfers and significantly reducing overhead. This capability is fundamental to achieving the high levels of performance required in scientific simulations, financial modeling, and large-scale data processing. The IBM 59Y1890 QLE7340 HCA is a specialized piece of hardware aimed at optimizing inter-server communication in environments where speed and efficiency are paramount.
