Liquid cooling innovation for a highly efficient data center

  • 功能


    Lenovo Neptune technology

    The ThinkSystem SD650 with Lenovo Neptune Direct to Node (DTN) technology utilizes warm-water cooling (up to 50⁰C) to remove heat from the CPUs, memory, I/O, local storage, and voltage regulators.

    Benefits of this solution include:

    • Superior heat conducting efficiency of water versus air, so critical server components operate at lower temperatures compared to air-cooled systems.
    • Running Intel Xeon Processor Scalable family CPUs up to 240W+ versus traditional air-cooled systems limited to 165W-205W.
    • Delivering greater performance with 30-40% data center energy savings.

    Innovative design

    The Lenovo ThinkSystem SD650 dual-node tray is designed for high performance computing (HPC), large-scale cloud, and heavy simulations. It supports workloads from technical computing to grid deployments to analytics and is ideally suited for fields such as research, oil and gas, and engineering. The SD650's unique water-cooling technology provides many key benefits. Compared to other technology, the SD650's direct water cooling:

    • Reduces data center energy costs by 40%
    • Increases system performance
    • Delivers 90% heat removal efficiency*
    • Creates a quieter data center
    • Enables data center growth without adding CRACs

    Maximum performance and management

    Designed to run the highest core-count Intel® Xeon® Scalable Family processors, the SD650 powers through demanding HPC workloads. Because water cooling removes more heat, CPUs can run in “turbo” mode nonstop, getting up to 10% greater performance from the CPU. For even greater system performance, the SD650 uses 2667MHz DDR4 memory and supports NVMe storage, high-speed EDR InfiniBand, and Omni Path adapters.

    The SD650 is managed by Lenovo Intelligent Computing Orchestrator (LiCO), a powerful management suite with an intuitive GUI that helps to easily manage large HPC cluster resources and accelerate development of AI applications.

    LiCO works with the most common AI frameworks, including TensorFlow, Caffe and Microsoft CNTK.

    Extreme density

    One 6U NeXtScale n1200 Enclosure accommodates up to 12 SD650 compute nodes. The enclosure houses up to 24 processors, 9.2TB of memory, 24 SFF SSDs or 12 SFF NVMe drives, and 24 M.2 boot drives. Each SD650 offers up to 12 more cores per U than the previous generation.*

    Leading energy efficiency

    The ThinkSystem SD650’s direct water-cooling design provides extreme energy efficiency. With up to 90% heat removal efficiency, the SD650 provides up to a 40% savings in data center energy expense including:

    • 25% reduction in annual air conditioning use
    • 5% energy savings by running CPUs cooler
    • 4% savings by eliminating fans in the compute nodes

    For example, a large super computing center reuses the hot water produced by direct water cooling to save an estimated 45% in electricity costs and uses it to produce chilled water.
