Notes:
[All] Costs fluctuate slightly from quarter to quarter based on actual JHPCE operational expenses. Posted cost in the above table were from FY2018Q2 charges.
[1] Scratch space is only visible on compute and transfer nodes. Scratch is not visible on the login node.
[2] Currently there is no quota on files in /sge_scratch/personal/, however we reserve the option to impose one if need be.
[3] Users with space in /legacy and /starter may want to consider moving to /dcl01/leased, as it is significantly less expensive.
[4] Backups are done of the /users filesystem. Other filesystems may be backed up upon arrangement with PI.
