Choice to provision users' data storage:	Pro	Con	Notes
Within the head node (status quo)	Sunk cost: Pay once and it lasts at least through warranty period, probably longer (no monthly costs) Known technology and proven performance.	May need to over-provision (pay extra up-front), speculating on future demands. Invest more now to reduce downtime due to future upgrade. Depended on same sub-systems, so off-site backup (such as EZ-Backup) is critically important.

	Fee based: Get only what you need.	Fee based: Monthly costs. Must confirm: Meets Matrix's performance needs? Includes off-site disaster-recovery backups. Can include versioning (uses 20% of the space).	Used pervasively in Chemistry research, with versioning turned on for all instances.
NAS		Must confirm: Meets Matrix's performance needs?
Dedicated, separate file server		Oliver not willing to have ChemIT set up and run?

Decision 2: Backups

How should Matrix be backed up?

...

Must include capacity to restore OS, applications and configurations, and users' data.
Current answer: Cornell CIT's EZ-Backup.
- Details: See "Scheraga - Cluster backup choices" for data informing this original decision.
Choices proposed by ChemIT, to work through with Czarek:
- TBA: Backup may be included in options considered for Decision 1.
  - If still required, ChemIT still recommends EZ-Backup.
