Engineered for large-scale cloud infrastructures and High Performance Computing (HPC), the Lenovo ThinkSystem SC750 V4 Neptune excels in intensive simulations and complex modeling. It’s designed to handle technical computing, grid deployments, and analytics workloads in various fields such as research, life sciences, energy, engineering, and financial simulation.
At its core, Lenovo Neptune applies 100% direct warm-water cooling, maximizing performance and energy efficiency without sacrificing accessibility or serviceability. The SC750 V4 integrates seamlessly into a standard 19" rack cabinet with the ThinkSystem N1380 Neptune enclosure, featuring a patented blind-mate stainless steel dripless quick connection.
This design ensures easy serviceability and extreme performance density, making the SC750 V4 the go-to choice for compute clusters of all sizes - from departmental/workgroup levels to the world’s most powerful supercomputers – from Exascale to Everyscale®.
Optimal Performance for HPC Workloads
Supporting the Intel® Xeon® 6900P-series, the ThinkSystem SC750 V4 Neptune stands as a powerhouse for demanding HPC workloads. Its industry-leading direct water-cooling system ensures steady heat dissipation, allowing CPUs to maintain accelerated operation and achieve up to a 10% performance enhancement.
The 6900P-series, boasting up to 128 Performance-cores, offers superior single-thread performance, AI acceleration in every core and native AVX512 matrix math instructions. This makes it an ideal fit for vectorized workloads in fields like biology and chemistry, including applications such as NAMD, GROMACS, LAMMPS, CP2K, and Quantum ESPRESSO, and boost performance for machine and deep learning workloads as well.
In addition, Intel® AMX BF16 and FP16 acceleration is integrated in every core for increased generative AI performance. With up to 128 AMX instances of AI accelerators per socket, Intel® Xeon® 6 processor gains up to 2x higher Llama-13B (BF16) gen to gen performance.
With 12 channels of high-speed DDR5 RDIMM or an impressive 8800MHz high-bandwidth MRDIMM capability, it excels in memory bandwidth-bound workloads, positioning it as a preferred choice for meteorology and engineering applications like WRF, ICON, OpenFOAM, and Fluent.
Completing the package with support for high-performance NVMe and high-speed, low latency networking with the latest Infiniband, Omnipath, and Ethernet choices, the SC750 V4 is your all-in-one solution for HPC workloads.
Simplifying System Management and Operation
The Lenovo ThinkSystem SC750 V4 Neptune is equipped with the new XClarity Controller 3 (XCC3). Leveraging the power of OpenBMC, XCC3 combines the flexibility of open-source with Lenovo’s advanced capabilities, offering an unprecedented level of efficiency and control in system management. It features advanced energy monitoring and management capabilities and a user-friendly interface, simplifying the management of complex HPC environments.
For higher level management and orchestration, the Lenovo HPC & AI Software Stack provides a fully tested and supported open-source software environment. It enables your administrators and users to utilize Lenovo’s supercomputing capabilities in the most effective and environmentally sustainable manner.
Our Confluent management system and Lenovo Intelligent Computing Orchestration (LiCO) web portal offer an interface designed to shield users from the complexities of HPC cluster orchestration and AI workloads management. This makes open-source HPC software accessible and consumable for all customers.
Lenovo Neptune® Technology
Since 2012, Lenovo’s direct water-cooling has consistently led the industry with advanced cooling innovations. The dedication to quality-engineering and performance-design is demonstrated by over a decade of delivering reliable water-cooled solutions worldwide.
Lenovo Neptune utilizes superior materials, including custom copper water loops and patented CPU cold plates, for full system water-cooling. Unlike systems that use low-quality FEP plastic, Neptune features durable stainless steel and reliable EPDM hoses. N1380 features an integrated manifold that offers a patented blind-mate mechanism with aerospace-grade drip-less connectors to the compute trays, ensuring safe and seamless operation.
Neptune is designed to operate at water inlet temperatures as low as the dew point allows, up to 45°C. This design eliminates the need for additional chilling and allows for efficient reuse of the generated heat energy in building heating or adsorption cold water generation. It uses treated de-ionized water as a coolant, a much safer and more efficient alternative to the commonly used PG25 Glycol liquid, reflecting our commitment to environmental responsibility.
Compared to an equivalent air-cooled system, the ThinkSystem SC750 V4 Neptune provides:
- Up to 10% performance increase through continuous turbo mode
- Up to 40% data center energy use reduction from server and infrastructure
- Up to 100% heat removal by water directly on the heat sources
- Up to 100% noise reduction by server fans in the data center
Streamlined Infrastructure for Every Scale
Each 13U Lenovo ThinkSystem N1380 Neptune enclosure houses eight Lenovo ThinkSystem SC750 V4 Neptune trays. Up to three N1380 enclosures fit into a standard 19" rack cabinet, packing 24 trays, 48 nodes, 96 processors, and 148TB of DDR5 Memory into just two 60x60 datacenter floor tiles.
Beyond the Neptune water-cooling infrastructure, the N1380 enclosure houses up to four ThinkSystem 15kW Titanium Power Conversion Stations (PCS), supplying internal system power to a 48V busbar. This innovative design merges power conversion, rectification, and distribution into a single PCS, a departure from traditional setups that demand separate units, resulting in best-in-class efficiency.
The Lenovo ThinkSystem N1380 Neptune design simplifies complex infrastructure management by integrating key components such as power routing with a busbar and water distribution through internal manifold. This means efficient power distribution, seamless hose connections, and orderly cable routing within your datacenter.
