Ideas:

• If the student's PI made use of lab allocations, then the student can have more than 5 TB on those same platforms, but not necessarily the full lab amount. This ensures continuity for the student.
• If the student's PI had purchased additional storage hardware, then it should remain available to the student for the remainder of its service life, at the PI's discretion (I don't know what else they'd do with it).
• Because the student's situation is different than students whose PIs are at UAB, there is a case to be made that this is an equitable solution, if not an equal solution.
• This only applies to students and not to staff, faculty, or other PIs. I might even narrow it further to graduate students.
• The above would need to be on a case-by-case basis, because the exact needs of each student can be quite variable. We would need to ask them how much they can "whittle down" the data to just their needs.
• Directed to PIs: "before you leave, make sure you do X to support the on-going work of your students remaining at UAB"
• Directed to students: "if your PI is leaving..."
