Cray CS300-LC System

Cray CS300-LC

The Cray CS300-LC cluster supercomputer delivers energy savings through the use of warm water heat exchangers instead of chillers. This innovative liquid-cooled design directly cools the compute processor and memory to more efficiently remove system heat. Based on modular, industry-standard platforms, the Cray CS300-LC system offers flexible configuration options with the latest processor technologies and multiple networking options.

Every Cray CS300-LC system is tightly integrated with Cray’s HPC cluster software stack addressing cluster communication efficiency, deployment and management. With an innovative liquid-cooling architecture, the Cray CS300-LC system delivers outstanding price/performance, easy remote management, monitoring and reporting for a lower TCO and faster ROI vs. traditional air-cooling architectures. The Cray CS300-LC is designed for capacity and data-intensive computing to help users solve massively parallel computing and Big Data analytics challenges.
