The #1 HPC Storage Choice for New Supercomputers

After only 5 years, Seagate continues to solidify its position as the number one choice for high-performance storage solutions designed for new supercomputers. In fact, 40% of the top 20 systems on TOP500’s list of the world’s fastest supercomputers are powered by Seagate. A clear demonstration that supercomputing is effectively meeting the vast and growing performance and massive capacity needs of HPC systems.

Seagate Owns 85% of the Intellectual Property Inside ClusterStor

While competitors may claim to have purpose-engineered systems, ClusterStor™ is truly the only purpose-engineered HPC storage solution that is designed, manufactured and supported by one company.

Seagate’s accomplished and unique industry experience informs the entire system, from the storage media to the software stack. Because of this full system integration, ClusterStor delivers on many levels where competitor systems cannot. You can expect better performance, efficiency, scalability and—ultimately—simplicity with ClusterStor.

Sustained Performance

Nobody beats ClusterStor on performance. Seagate reliably delivers the highest performance in the most demanding, data-intensive HPC and high-performance data analytics (HPDA) environments.

ClusterStor was first to predictably deliver sustained HPC-performance throughput over 1TB/s

5 of the 6 fastest systems, are powered by Seagate, including the first system to break the 1 TB/s barrier at the National Center for Supercomputing Applications (NCSA) running after 5 years

ClusterStor currently supports the fastest HPC-sustained throughput in the industry—up to 1.7TB/s with data storage capacity over 80 petabytes (PB)

Efficiency/TCO Savings

Seagate’s number one ranking is significant and starts with system efficiency at the device level – the core of our business. Other vendors deliver about 50% of the performance throughput per drive compared to ClusterStor, meaning that vendor systems require 2× the number of drives to achieve the same level of performance. These solutions waste valuable power, cooling resources and data center floor space.

By contrast, ClusterStor’s unique system architecture requires less hardware, provides efficient flow among all components, and typically requires fewer soft costs such as time to resolution, if issues arise. Seagate builds each system based on your specific needs, delivering the greatest performance efficiency along with a lower total cost of ownership (TCO).

Infinite Scalability

Unlike most cobbled-together legacy systems, ClusterStor is infinitely scalable. We’ve scaled systems up to 100PB with no loss of efficiency or performance! Because all of our systems are engineered to work together seamlessly, we can help you scale as much or as little as you need, exactly when you need it. Best of all, we simplify the user experience through ClusterStor Manager allowing administrators to easily monitor performance of the entire system from a single dashboard.

Seagate Simple

There's no arguing that HPC storage is hard; the complexity involved in designing an efficient system with the right performance levels, file systems, speed, scalability and data availability can be daunting. But if your HPC legacy system is also cobbled together, as most are, with each component manufactured for its independent performance, then chaos reigns. Sometimes it’s better to start fresh.

What we call Seagate Simple.

Simple is defined as clean, consistent and elegant. Seagate’s mission is to reduce complexity and to provide easy, unfettered access to data with seamless scalability.
