Lustre is a scale-out file system typically used in High-Performance Computing applications. As a parallel distributed file system, Lustre is deployed where high parallelism and bandwidth are required. Lustre is open-source software developed originally as a research project at Carnegie Mellon and since has had commercial implementations distributed and supported as complete storage solutions. The first such company with a distribution and product was ClusterStor which was subsequently acquired by Sun Microsystems. Through different acquisitions and variations, the distribution and support for the commercial version is now with DataDirect Networks with Lustre offered in the DDN Exascaler product. The open-source distribution continues and is freely downloadable. Many add-on enhancements were developed independently and may be installed on top of the Lustre environment.
Architecturally, there is no limit to the number of nodes and capacity, but actual implementations are more modest, with the largest containing 2 Billion files and 55 PB in a production environment. With the open-source offering and high performance, a majority of Lustre implementations are in research labs and universities – often attached to supercomputers.
