HPC applications that require massive throughput and highly parallel access are challenging traditional SAN and NAS storage technologies. Storage systems designed to serve the needs of the last 10 years are no longer able to deliver the scalable bandwidth and file system locking capabilities required by today's HPC environments. To satisfy these requirements, an extremely high performance approach which integrates file system and storage media into one extremely high performance file storage appliance is needed. This approach would solve both today's requirements and scale to accommodate the unpredictable growth of Big Data in the future.
EXAScaler, is a next generation parallel file storage system appliance that combines DDN award-winning HPC storage technology with the open-source Lustre® File System. DDN has leveraged its leadership in supporting the world's largest file storage systems for over a decade to combine these best of breed storage technologies into a tightly integrated, easy to use single appliance that delivers scalable, clustered storage performance. Built by the HPC experts, and supported by the world's most skilled parallel I/O team, the EXAScaler blueprint is known worldwide as the gold standard in HPC storage clustering and powers the largest number of Top500® Supercomputer Sites, worldwide.

TiTech needed to evolve their Tsubame supercomputer architecture to support petascale applications, increase cluster & storage capacity and deliver the highest quality of service to their supercomputer users in the international research community.
DDN & HP delivered the massively scalable DDN | EXAScaler to deliver over 60GB/s of shared file system throughput to support a ~2.4 Petaflop resource. Improvements include:

ORNL required an extremely scalable, high performing storage solution for the Jaguar supercomputer to enable Petascale genomics research
At 240GB/s, DDN delivered the world's most scalable bio-informatics storage solution to run on the United State’s fastest supercomputer.

Driven by business opportunities, this oil and gas company needed to scale production operations and increase their seismic computation by 10X. This required an advanced technology that would be capable of providing a significant increase in performance and scale requirements for their backend storage.
DDN deployed EXAScaler, serving as their infrastructure which will enable substantial growth of their production operations, making them ready for a 10-100x increase in seismic computations in the future.

Driven by the rapid increase in both data & performance requirements of the next-gen Illumina sequencers, Sanger needed an infrastructure upgrade to support this new genomics technology.
Sanger procured 3 SFA10K systems to power a scale-out, QDR InfiniBand enabled EXAScaler storage cluster. With over 30GB/s of performance and petabytes of capacity, Sanger is now ready to tackle the most extreme workflows their Illumina sequencers can throw at them.

DDN has long been a partner of choice for organizations that need to scale far beyond conventional file system limits. DDN continues to
reaffirm its position at the vanguard of the scalable systems marketplace, and therefore as one of the storage leaders of the contemporary Big
