New guidance: Don’t delay migrating files from HPSS

November 1, 2019

CISL is advising users who have data holdings on the High-Performance Storage System (HPSS) to begin deleting files that are no longer needed and to move other data to alternative storage systems soon. While the system will reach its end of life in 2021, getting a late start on the process increases the likelihood that important data will be lost when HPSS is shut down.

Early action is necessary because of the tape archive’s limited bandwidth and the time needed to complete large data transfers. Also, HPSS will be put into read-only mode soon, so users need to review their workflows and stop writing data to tape if they have not already done so.

Newly published documentation – Migrating files from HPSS – lays out the recommended process for identifying and organizing HPSS holdings, copying files that need to be preserved to another storage resource, and deleting files that are no longer needed. Upcoming CISL Daily Bulletin announcements will follow as new tools and expanded documentation become available to support the data migration. In the meantime, please contact CISL for advice on individual workflows, accessing data movers, and storage options.
