Lustre File System: High-Performance Storage Architecture and Scalable Cluster File System

Lustre is a storage architecture for clusters. The central component is the Lustre file system, a shared file system for clusters. The Lustre file system is currently available for Linux and provides a POSIX-compliant UNIX file system interface. A complementing Solaris version is planned for 2008. The Lustre architecture is used for many different kinds of clusters. It is best known for powering seven of the ten largest High-Performance Computing (HPC) clusters in the world, with tens of thousands of client systems, PetaBytes (PB) of storage and hundreds of gigabytes per second (GB/sec) of I/O throughput. Many HPC sites use Lustre as a site-wide global file system, servicing dozens of clusters on an unprecedented scale.
