What is Lustre?
Lustre is a scalable, secure, robust, highly-available cluster file system. It is designed, developed and maintained by Sun Microsystems, Inc.

The central goal is the development of a next-generation cluster file system which can serve clusters with 10,000's of nodes, provide petabytes of storage, and move 100's of GB/sec with state-of-the-art security and management infrastructure.

Lustre runs on many of the largest Linux clusters in the world, and is included by Sun's partners as a core component of their cluster offering (examples include HP StorageWorks SFS, and the Cray XT3 and XD1 supercomputers). Today's users have also demonstrated that Lustre scales down as well as it scales up, and runs in production on clusters as small as 4 and as large as 25,000 nodes.

The latest version of Lustre is always available from Sun Microsystems, Inc. Public Open Source releases of Lustre are available under the GNU General Public License. These releases are found here, and are used in production supercomputing environments worldwide.

To be informed of Lustre releases, subscribe to the lustre-announce mailing list.

Lustre development would not have been possible without funding and guidance from many organizations, including several U.S. National Laboratories, early adopters, and product partners.
