Storage
Home Directories
Users are provided a default allocation of 100G of storage on our shared storage appliance.
User home directories are retained for up to one year after the owner leaves the college, at which point, their directory is removed, and any used storage is reclaimed.
Project Storage
Depending on project needs, we can provide up to 5TB of shared storage, which can be made available cluster-wide or via Globus.
For projects requiring more, we will work with stakeholders to engineer an appropriate solution that provides the necessary flexibility and resources while also meeting constraints imposed by applicable funding sources.
Scratch Storage
Each compute node is equipped with fast local storage which is available for use. In particular, the environment variable $SCRATCH_PATH contains the location of local scratch storage which has been preconfigured for your user.
It's important to note that the contents of scratch are node local, so content available on one compute node will not be automatically available on another.
We reformat each node's scratch disk before the start of each semester, and will periodically purge files older than 90 days through out the year.
Mapped Collections
The home directories on the ALPhA & Lovelace clusters are accessible through Globus via the following mapped collections respectively:
ALPhA Cluster: Home DirectoryDavidson College: Home Directory
Additionally, research projects with dedicated project storage can request that storage be made available through Globus via a mapped collection (contact rc@davidson.edu for more information).
