Lustre® File System

Lustre logo

The Lustre® file system is a open source, parallel file system that supports the requirements of leadership class HPC and Enterprise environments worldwide.  Lustre provides a POSIX compliant interface and scales to thousands of clients, hundreds of petabytes of storage, and has demonstrated over several terabytes per second of sustained I/O bandwidth.  Many of the largest and most powerful supercomputers on Earth today are powered by the Lustre file system, including over 60% of the TOP100 sites.

In recent years the Lustre 2.x release series has delivered major new features and enhancements, enabling the success of Lustre not only in demanding high performance computing (HPC) environments, but also the challenging world of Machine Learning (ML) and Artificial Intelligence (AI), Cloud, Big Data and Enterprise computing.

The Lustre Community website supports the open source community — developers, admins, and users — providing downloadable Lustre releases, documentation, development tree access, issue reporting, working groups, mailing lists, and more. We encourage you to download and use Lustre, participate in the community, and provide your input and support as we grow Lustre success worldwide.

OpenSFS is a nonprofit organization founded in 2010 to advance Lustre development, ensuring it remains vendor-neutral, open, and freely downloadable. OpenSFS participants include vendors and customers who employ the world’s best Lustre file system experts, implementing and supporting Lustre solutions across HPC and commercial enterprises. OpenSFS actively promotes the growth, stability and vendor neutrality of the Lustre file system.

Here at OpenSFS, we live and breathe Lustre.
