Cray CS400-LC System

Cray® CS400-LC™ Cluster Supercomputers

The CS400-LC™ system is our liquid-cooled cluster supercomputer. Designed for significant energy savings, it features liquid-cooling technology that uses warm water heat exchangers instead of chillers to cool system components. Compared to traditional air-cooled clusters, the CS400-LC system can deliver three times more energy efficiency with immediate to one-year payback cycles typical.

Along with lowering operational costs, the CS400-LC system also offers the latest x86 processing, coprocessing and accelerator technologies from Intel and NVIDIA in a highly scalable package. Industry-standard server nodes and components have been optimized for HPC and tightly integrated with a comprehensive HPC software stack, creating a unified system that excels at capacity and data-intensive workloads.
