Smarter Cluster Supercomputing from the Supercomputer Experts Lowers energy costs; datacenter PUE of 1.1 or lower Capable of up to 80 percent heat capture
Maximize Your Productivity with Flexible, High-Performance Cray CS400 Liquid- Cooled Cluster Supercomputers In science and business, as soon as one question is answered another is waiting. And with so much depending on fast, accurate answers to complex problems, you need reliable high performance computing (HPC) tools matched to your specific tasks. Understanding that time is critical and all HPC problems are not created equal, we developed the Cray CS400 cluster supercomputer series. These systems are industry standards-based, highly customizable, easy to manage, and purposefully designed to handle the broadest range of medium- to large-scale simulations and data-intensive workloads. All CS400 components have been carefully selected, optimized and integrated to create a powerful, reliable high-performance compute environment capable of scaling to over 27,000 compute nodes and 46 peak petaflops. Flexible node configurations featuring the latest processor and interconnect technologies mean you can get to the solution faster by tailoring a system to your specific HPC applications needs. Innovations in packaging, power, cooling and density translate to superior energy efficiency and compelling price/performance. Expertly engineered system management software instantly boosts your productivity by simplifying system administration and maintenance, even for very large systems. Cray has long been a leader in delivering tightly integrated supercomputer systems for large-scale deployments. With the CS400 system, you get that same Cray expertise and productivity in a flexible, standards-based and easy-to-manage cluster supercomputer. CS400-LC Cluster Supercomputer: Liquid-Cooled and Designed for Your Workload The CS400-LC system is our direct-to-chip warm water-cooled cluster supercomputer. Designed for significant energy savings, it features liquid-cooling technology that uses 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 typical payback cycles ranging from immediate to one year. Along with lowering operational costs, the CS400-LC system offers the latest x86 processor technologies from Intel in a highly scalable package. Industry-standard server nodes and components have been optimized for HPC and paired with a comprehensive HPC software stack, creating a unified system that excels at capacityand data-intensive workloads.
Innovative Liquid Cooling Keeps Your System Cool and Energy Costs Low Designed to minimize power consumption without compromising performance, the CS400-LC cluster supercomputer uses an innovative heat exchange system to cool system processors and memory. Outdoor Dry Cooler The heat exchange cooling process starts with a coolant distribution unit (CDU), connected to each rack, and two separate cooling loops. One loop delivers warm or cool facility water to the CDU, where the heat is exchanged and the now-hot facility water exits the other end of the loop. A second loop repeats the process at the server level. A double-sealed low-pressure secondary loop, with dripless quick connects, cools the critical server components. It delivers cooled liquid to the servers where pump/cold plate units atop the processors capture the heat, and the now-hot liquid circulates back to the CDU for heat exchange. Facility water and server loop liquid never mix liquid-to-liquid heat exchangers within the CDU transfer heat between the loops. Facility Water Low Pressure Server Loop Coolant Distribution Unit (CDU) Server Cooler This isolated dual-loop design safeguards the nodes. First, the server loop is low pressure and low flow server loop components are not subject to the high pressure of the facility loop. Second, the server loop is prefilled with nonconductive, deionized water containing additives to prevent corrosion. Since it requires less powerful fans on the servers and fewer air conditioning units in the facility, the CS400-LC system reduces typical energy consumption by 50 percent with predicted power usage effectiveness (PUE) of 1.1 or lower. The system can also capture up to 80 percent of heat from the server components for possible reuse. Additionally, leak detection and prevention features are tightly integrated with the system remote monitoring and reporting capabilities. Choice of Flexible, Scalable Configurations Flexibility is at the heart of the Cray CS400-LC system design. At the system level, the CS400-LC cluster is built on the Cray GreenBlade platform. Comprising server blades and chassis, the platform is designed to provide mix-and-match building blocks for easy, flexible configurations, at both the node and whole system level. Among its advantages, the GreenBlade platform offers high density (up to 60 compute nodes per 42U rack), excellent memory capacity (up to 1,024 GB per node), many power and cooling efficiencies and a built-in management module for industry-leading reliability. CS400-LC Hardware Configuration Options Two-socket x86 Intel Xeon processors Large memory capacity per node Multiple interconnect options: 3D torus/fat tree, single/dual rail FDR InfiniBand Local hard drives in each server Choice of network-attached file systems and Lustre-based parallel file storage systems The CS400-LC system features the latest Intel Xeon processors. It offers multiple interconnect and network topology options, maximum bandwidth, local storage, many network-attached file system options and the ability to integrate with the Cray Sonexion scaleout Lustre system, providing fast, high-performance scratch and primary storage. Within this framework, the Cray CS400-LC system can be tailored to multiple purposes from an all-purpose cluster, to one suited for shared memory parallel tasks, to a system optimized for hybrid compute- and data-intensive workloads. Nodes are divided by function into compute and service nodes. Compute nodes run parallel MPI and/or Open MP tasks with maximum efficiency, while service nodes provide I/O and login functions. Compute nodes feature two Intel Xeon processors per node and up to 1,024 gigabytes of memory. Each node can host one local hard drive. With industry-standard components throughout, each system configuration can be replicated over and over to create a reliable and powerful large-scale system.
Easy, Comprehensive Manageability A flexible system is only as good as your ability to use it. The Cray CS400-LC cluster supercomputer offers two key productivity-boosting tools a customizable HPC cluster software stack and the Cray Advanced Cluster Engine (ACE ) system management software. Cray HPC Cluster Software Stack The HPC cluster software stack consists of a range of software tools compatible with most open source and commercial compilers, debuggers, schedulers and libraries. Also available as part of the software stack is the Cray Programming Environment, which includes the Cray Compiling Environment, Cray Scientific and Math Libraries, and Performance Measurement and Analysis Tools.

Built-in Energy Efficiencies and Reliability Features Lower Your TCO Energy efficiency features, combined with our long-standing expertise in meeting the reliability demands of very large, high-usage deployments means you get more work done for less. In addition to liquid cooling, the CS400-LC options for additional power and cost savings include high-efficiency load balancing power supplies and a 480V power distribution unit with a choice of 208V or 277V three-phase power supplies. It means you can use industry-standard 208V and 230V power as well as 277V (single-phase of a 480V three-phase input) and reduce power loss caused by step-down transformers and resistive losses as the power is delivered from the wall directly to the rack. Reliability is built into the system design, starting with our careful selection of boards and components. Then multiple levels of redundancy and fault tolerance ensure the system meets your uptime needs. The CS400-LC cluster has redundant power, cooling and management servers and redundant networks all with failover capabilities. Intel Xeon Processor E5-2600 Product Family The Intel Xeon processor is at the heart of the agile, efficient datacenter. Built on Intel s industry-leading microarchitecture based on the 14nm second-generation Tri-Gate transistor technology, the Intel Xeon processor supports high-speed DDR4 memory technology with increased bandwidth, larger density and lower voltage over previous generations. The Intel support for PCI Express (PCIe) 3.0 ports improves I/O bandwidth, offering extra capacity and flexibility for storage and networking connections. The processor delivers energy efficiency and performance that adapts to the most complex and demanding workloads.
