| + | ==== GRID storage ==== | ||
| + | |||
| + | Lunarc hosts a GRID storage for ATLAS. Currently we are migrating from a 20TB storage to a 100TB. | ||
| + | |||
| + | The local storage GRID name is '' SE-SNIC-T2_LUND_LOCALGROUPDISK '' | ||
| + | |||
| + | One can interact through it using the Rucio client. It cannot be mounted directly on the cluster. Data can only be moved to and fro. Access is restricted to **ATLAS** members. | ||
| + | |||
| + | Details on how to access this storage are at this page: http://www.hep.lu.se/grid/localgroupdisk.html | ||
| + | |||
| + | More on how to do transfers at [[aurora_cluster:moving_data | Moving data to and from the cluster]] | ||
| - | ^ Storage path ^ Intended usage ^ Size ^ | ||
| - | | ''/project/hep/fs3/shared'' | data that is meant to stay for long time | 35TB | | ||
| - | | ''/project/hep/fs4/scratch'' | temporary data | 35TB | | ||
| ===== Mathematical Physics ===== | ===== Mathematical Physics ===== | ||
| - | At the moment, only the user folders are available. We are negotiating a 10TB common storage with Lunarc. More information is soon to come. | + | At the moment, only standard LUNARC user folders are available, to my knowledge. Please contact me if you want this information to be updated. |
