up to provide support and development in an open community development model, including Whamcloud, Open Scalable File Systems, Inc. (OpenSFS), EUROPEAN Open File Systems (EOFS) and others. By the end of 2010, most Lustre developers had left Oracle. Braam and several associates joined the hardware-oriented Xyratex when it acquired the assets of ClusterStor, while Barton, Dilger, and others formed software startup Whamcloud, where they continued to work on Lustre. In August 2011, OpenSFS awarded a contract for Lustre feature development to Whamcloud. This contract covered the completion of features, including improved Single Server Metadata Performance scaling, which allows Lustre to better take advantage of many-core metadata server; online Lustre distributed filesystem checking (LFSCK), which allows verification of the distributed filesystem state between data and metadata servers while the filesystem is mounted and in use; and Distributed Namespace Environment (DNE), formerly Clustered Metadata (CMD), which allows the Lustre metadata to be distributed across multiple servers. Development also continued on ZFS-based back-end object storage at Lawrence Livermore National Laboratory. These features were in the Lustre 2.2 through 2.4 community release roadmap. In November 2011, a separate contract was awarded to Whamcloud for the maintenance of the Lustre 2.x source code to ensure that the Lustre code would receive sufficient testing and bug fixing while new features were being developed. In July 2012 Whamcloud was acquired by Intel, after Whamcloud won the FastForward DOE contract to extend Lustre for exascale computing systems in the 2012 timeframe. OpenSFS then transitioned contracts for Lustre development to Intel. In February 2013, Xyratex Ltd., announced it acquired the original Lustre trademark, logo, website and associated intellectual property from Oracle. In June 2013, Intel began expanding Lustre usage beyond traditional HPC, such as within Hadoop. For 2013 as a whole, OpenSFS announced request for proposals (RFP) to cover Lustre feature development, parallel file system tools, addressing Lustre technical debt, and parallel file system incubators. OpenSFS also established the Lustre Community Portal, a technical site that provides a collection of information and documentation in one area for reference and guidance to support the Lustre open source community. On April 8, 2014, Ken Claffey announced that Xyratex/Seagate was donating the lustre.org domain back to the user community, and this was completed in March, 2015. In June 2018, the Lustre team and assets were acquired from Intel by DDN. DDN organized the new acquisition as an independent division, reviving the Whamcloud
