Product Description
The Mellanox MHQH19B-XTR is a high-performance network interface card (NIC) designed to deliver 40 Gigabit Ethernet connectivity. This adapter is built upon the robust Mellanox ConnectX-3 Pro technology, known for its efficiency, scalability, and advanced features tailored for demanding environments such as high-performance computing (HPC) clusters, enterprise data centers, and cloud infrastructures. The single-port design, typically utilizing a QSFP (Quad Small Form-factor Pluggable) connector, allows for high-density deployments and efficient use of PCIe slots. Connecting via a PCI Express (PCI-E) interface, the MHQH19B-XTR ensures a high-bandwidth pathway to the host system, enabling it to handle the full 40Gb/s throughput without becoming a bottleneck. This adapter is engineered to provide extremely low latency and high message rates, which are critical for parallel processing, distributed storage, and real-time data analytics. It supports various advanced features, including RDMA (Remote Direct Memory Access) over Ethernet (RoCE) and InfiniBand, which allow for direct memory access between applications on different servers, bypassing the operating system kernel and significantly reducing latency and CPU utilization. The Mellanox MHQH19B-XTR is an ideal choice for applications that require massive data movement and fast inter-process communication. Its capabilities are essential for accelerating workloads in scientific research, financial modeling, big data processing, and storage networking. The reliability and performance offered by this adapter make it a cornerstone for building modern, high-speed network infrastructures.
