Lustre is a massively parallel distributed file system, used for large scale cluster computing. Lustre file systems are used in compute clusters ranging from small workgroup clusters to large-scale, multi-site clusters. Lustre file systems can support up to tens of thousands of client systems, petabytes (PBs) of storage and hundreds of gigabytes per second (GB/s) of I/O throughput. Due to Lustre’s high scalability, businesses such as Internet service providers, financial institutions, and the oil and gas industry deploy Lustre file systems in their data centers. Fifteen of the top 30 supercomputers in the world use Lustre file systems, the Jaguar supercomputer at Oak Ridge National Laboratory (ORNL) and one of the largest systems in Europe at CEA. DDN provides the storage solution for more than 70% of the Lustre systems in the Top500 listing of the world’s fastest supercomputers.
