Attached to Hellgate is the Jumbo storage system. It can store up to 5.3 petabytes of data.
When an account is created for hellgate three storage directories are set up for each user; a Home, Project, and Scratch directory. Each with different purposes and default Quotas(storage limits)
Home:
Quotas for home directories are 500GB and allocated per user, they are only accessible to the owning user and where you land when first logging in. As is common for other HPC systems this storage is primarily meant to be used as a staging area for unique software, moving files to-from a local computer, storing scripts, etc.
- /mnt/beegfs/hellgate/home/<netID>
Scratch:
Quotas for Scratch are set to 5TB and allocated per lab group, directories are visible to other members of the same lab group. Scratch directories leverage NVME drives but offer no redundancy, they are optimized for high read-write speed and intended for output for running jobs. Typically on HPC systems Scratch space is indented for fairly short term storage, with common retention policies of ~90 days.
- /mnt/beegfs/scratch/<netID>
Project:
Quotas for Project directories are set at 10TB and also allocated per lab group, similarly visible to other lab members. Project directories use the Hard disc drives available on Jumbo and are configured with mirroring, they do not have very fast read-write speed compared to scratch space but are much more stable and resilient to faults. With data retention policies typically closer to 2-3 years, this is intended to store the desired/good results and data used for specific projects.
