This paper is a product for the Department of Energy?s (DOE) Office of Science (OS) reporting on the feasibility of using HPSS into the Extreme Scale era of storage (2018 - 2022). The initial sections provide a summary of the systems environment and expected archival storage requirements extracted from other Extreme Scale workshop reports conducted since 2007 by various applications and programs within the DOE OS. These high level requirements aid in identifying long-term data storage system features that support Extreme Scale science. Participants also separately forecasted data growth in established long-term data storage systems through 2018 - 2022 to get a picture of the amount of data that systems will need to manage. The report concludes that HPSS is well positioned to meet the requirements projected for the Extreme Scale era and provides recommendations from the HPSS Collaboration to the DOE Office of Science for ensuring that HPSS can meet these extreme scale storage requirements of 2018 - 2022.
