Avoid Globus file transfers directly from HPSS tape archive

August 25, 2020

CISL storage engineers are advising users to avoid direct Globus file transfers from the HPSS tape archive to Campaign Storage or other remote Globus endpoints. The Globus-HPSS connector is considerably slower than using the HSI commands in the recommended process described here.

Users attempting large Globus transfers with the Globus-HPSS connector have encountered numerous timeouts and restarts and wasted valuable system cycles. The Globus interface to HPSS is useful only for transferring a small number of files or for listing some directories.

Please see the CISL documentation and our Migrating Files from HPSS tutorial for help and best practices with copying important files to other storage resources.
