P A R T I - Lustre Architecture

Lustre Architecture

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.

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 (PBs) 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.
