Lenovo Neptune™ accelerated
Lenovo ThinkSystem SD665-N V3 is based on our fifth generation Lenovo Neptune™ direct water cooling platform and on two 4th Generation AMD EPYC™ Processors with NVIDIA HGX™ H100 4-GPU acceleration and NVIDIA NDR InfiniBand networking.
The combination of market leading NVIDIA acceleration technology with the market leading water cooling solution from Lenovo results in extreme performance in an extreme dense packaging. A single rack of Lenovo ThinkSystem SD665-N V3 nodes is more than doubles the performance of the previous generation with up to 5.8 PetaFLOPS High Performance Computing (HPC) or almost 200 PetaFLOPS Artificial Intelligence (AI) peak performance, occupying only 0.72m² (less than 8 ft²) of data center floor space.
Accelerating your applications
On the SD665-N V3, four NVIDIA H100 Tensor Core GPU are interconnected through NVLink, delivering substantial performance improvements for HPC, AI training, and inference workloads. The H100 supports the Lenovo HPC philosophy to enable customers From Exascale to Everyscale™. Together with NVIDIA InfiniBand networking, it scales efficiently to thousands of GPUs or, with NVIDIA Multi-Instance GPU (MIG) technology, can be partitioned into seven GPU instances to accelerate smaller workloads.
With NVIDIA® CUDA® the most widely used parallel computing platform and programming model for GPUs is available free of charge to help you accelerate the more than 700 supported HPC applications and every major deep learning framework, for example:
- Chemistry like Gaussian and GROMACS
- Finite Elements like LS-DYNA and Simulia Abaqus
- Fluid Dynamics like OpenFOAM and ANSYS Fluent
- Molecular Dynamics like NAMD and AMBER
- Weather and Climate like WRF and ICON
The Lenovo ThinkSystem SD665-N V3 also supports NVIDIA® NGC™ providing pre-trained models, training scripts, optimized framework containers and inference engines for popular deep learning models.
Lenovo Neptune™: Leading water cooling technology
A decade of experience in direct water cooling sets Lenovo apart. With a meticulous focus on low-pressure drop and highest quality materials, Lenovo achieves the best-in-class reliability.
The SD665-N V3 leverages copper and brazed connections guaranteeing leak-free operations at extreme scale, even at high pressure.
Another important differentiation is superior water loop design enabling up to 45 °C inlet temperatures for the highest energy reuse efficiency. The new water loop design optimizes performance with increased frequency while ensuring temperature uniformity, preventing Thermal Jitter for consistent application performance.
Water cooling is an end-to-end process that starts at manufacturing. Through Helium and Nitrogen pressure tests from the node to the completed rack, the SD665-N V3 provides consistent quality at the highest standards. This approach also allows Lenovo to ship the systems pressurized without needing to send hazardous antifreeze-components to our customers.
Solutions That Scale
Lenovo ThinkSystem SD665-N V3 is delivered as fully integrated Lenovo Scalable Infrastructure (LeSI) solution. LeSI provides Best Recipe guides to warrant interoperability of hardware, software and firmware among a variety of Lenovo and third-party components.
In addition to interoperability testing, LeSI hardware is pre-integrated, pre-cabled, and pre-loaded with the best recipe and, optionally, an OS image. It is then tested at the rack level in manufacturing, to ensure a reliable delivery and minimize installation time in the customer data center.
Lenovo ThinkSystem SD665-N V3 is enabled with Lenovo HPC & AI Software Stack, where you can support multiple users and scale within a single cluster environment. Lenovo HPC & AI Software Stack provides our HPC customers with a fully tested and supported open-source software stack to enable their administrators and users for the most effective and environmentally sustainable consumption of Lenovo Supercomputing capabilities.
Our Confluent management system and Lenovo Intelligent Computing Orchestration (LiCO) Web portal provide an interface designed to abstract the users from the complexity of HPC cluster orchestration and AI workloads management, making open-source HPC software consumable for every customer.
The LiCO Web portal provides workflows for both AI and HPC, and supports multiple AI frameworks, allowing you to leverage a single cluster for diverse workload requirements.
Data Center Reliability Leader
At Lenovo, we take a customer-centric approach, which is why ThinkSystem servers consistently rank #1 in reliability. Also, Lenovo is the leading provider of Supercomputers in the TOP500. The ThinkSystem SD665-N V3 provides the latest in performance and reliability in a scalable solution for enterprise and research.
