ThinkSystem SD650-N V3

The ThinkSystem SD650-N V3 Neptune DWC node is the next-generation high-performance server based on the fifth generation Lenovo Neptune™ direct water cooling platform.

With two 5th Gen Intel Xeon Scalable or Intel Xeon CPU Max Series processors, along with four NVIDIA H100 SXM5 GPUs, the ThinkSystem SD650-N V3 server features the latest technology from Intel and NVIDIA, combined with Lenovo's market-leading water-cooling solution, which results in extreme performance in an extreme dense packaging, supporting your application from Exascale to Everyscale™.

The direct water cooled solution is designed to operate by using warm water, up to 45°C (113°F) depending on the configuration. Chillers are not needed for most customers, meaning even greater savings and a lower total cost of ownership. The nodes are housed in the upgraded ThinkSystem DW612S enclosure, a 6U rack mount unit that fits in a standard 19-inch rack.

The Lenovo ThinkSystem SD650-N V3 server tray is designed for High Performance Computing (HPC), large-scale cloud, heavy simulations, and modeling. It implements Lenovo Neptune™ Direct Water Cooling (DWC) technology to optimally support workloads from technical computing, grid deployments, analytics, and is ideally suited for fields such as research, life sciences, energy, simulation, and engineering.

The unique design of ThinkSystem SD650-N V3 provides the optimal balance of serviceability, performance, and efficiency. By using a standard rack with the ThinkSystem DW612S enclosure equipped with patented stainless steel drip-less quick connectors, the SD650-N V3 provides easy serviceability and extreme density that is well suited for clusters ranging from small enterprises to the world's largest supercomputers.

The Lenovo Neptune™ direct liquid cooling doesn't use risky plastic retrofitting but instead custom-designed copper water loops, so you have peace of mind implementing a platform with liquid cooling at the core of the design.

Compared to other technology, the SD650-N V3 direct water cooling:

• Reduces data center energy costs by up to 40%
• Increases system performance by up to 10%
• Delivers up to 100% heat removal efficiency (depending on the environment)
• Creates a quieter data center with its fan-less design
• Enables data center growth without adding computer room air conditioning

Lenovo’s direct water-cooled solutions are factory-integrated and are re-tested at the rack-level to ensure that a rack can be directly deployed at the customer site. This careful and consistent quality testing has been developed as a result of over a decade of experience designing and deploying DWC solutions to the very highest standards.
