The Lustre(R) File System has been designed from the ground up to meet the demands of the world's largest high-performance compute clusters. Our state of the art object-based storage architecture redefines scalability and provides groundbreaking I/O and metadata throughput. Lustre currently scales to thousands of nodes and hundreds of terabytes of storage -- with active development to support tens of thousands of nodes, trillions of files, and petabytes of data. In recent testing on production supercomputing clusters, Lustre achieved an aggregate parallel I/O throughput of 22 GB/s utilizing in excess of 90% of the available raw I/O bandwidth.1
