The central goal of the development of a next-generation cluster file system which capable of serving clusters with 10,000's of nodes, petabytes of storage, move 100's of GB/sec with state of the art security and a easy to use management infrastructure.
Lustre is incorporated into most of todays largest Linux clusters in the world, which includes, CFS's partners who offer lustre as a core component of their cluster offerings. These include HP StorageWorks SFS, and the Cray XT3 and XD1 supercomputers). Users have also demonstrated that Lustre scales well in both the directions, running in production clusters as small as 4 and as large as 15,000 nodes.
The latest version of Lustre is always available from Cluster File Systems, Inc. Public Open Source releases of Lustre are made under the GNU General Public License.
