To support those projects, ORNL acquired and ran the NSL UniTree storage management product.</p> <p>In 1993, a follow-on to NSL UniTree known as HPSS was being designed by IBM and a collaboration of Department of Energy (DOE) and national laboratories (Sandia, Lawrence Livermore, and Los Alamos National Laboratories). ORNL joined that collaboration and took on the responsibility for the storage system management (SSM) portion of the product, for which the <a href="https://www.olcf.ornl.gov/olcf-resources/rd-project/hpss-development/">ORNL HPSS development team</a> continues to be responsible.</p> <p>ORNL continued with NSL UniTree production use until 1997, at which time the conversion to HPSS was completed. In 1997, HPSS won an R&D 100 Award, based on the work of five DOE labs鈥擮ak Ridge, Lawrence Berkeley, Lawrence Livermore, Los Alamos, and Sandia National Laboratories鈥攁nd IBM Houston Global Services.</p> <p>In 1998, the OLCF was producing 300 GB of data per month and providing 1 TB of disk storage space. More than 20 years later, the OLCF archives petabytes (PB) of data per month and provides 23.3 PB of disk storage space and 132 PB of tape storage space.</p> </div> </div> </div></div></div></div> </div> </div> </div> </div></div> <div id="fws_674bdc1ddbaac" data-column-margin="default" data-midnight="dark" data-top-percent="4%" data-bottom-percent="4%" class="wpb_row vc_row-fluid vc_row full-width-section" style="padding-top: calc(100vw * 0.04);
