Restore the system

Assumptions

Original Scheraga RAID card is OK.

...

• If other drives are non-operational, may have to buy more drives.

Rebuild 1: Operating system

Summary recommendation

• Retain 100% functionality.
• No purchases necessary.
• Reuse both existing OS hard drives.
  • The data currently on the hard drives can be deleted.

Details

Unknown: ChemIT to confirm drives pass a drive test. If they pass the test, re-deploy them.

...

• 160GB of space.
  • Two 160GB drives on hardware RAID card, mirrored (RAID 1).
  • OS using ~77GB of this space and not growing rapidly, so that's plenty of space.

Rebuild 2: Data

Summary recommendation

• Don't retain 100% functionality
  • Retain full data storage capability, with same redundant configuration.
  • Remove in-box versioning (Back in Time copy), decreasing number of disks required.
• No purchases necessary.
• Reuse existing OS hard drives which still work (at leest 4 of the original 6).
  • The data currently on the hard drives can be deleted.

Details

One hard drive has a broken board. Current plan does not require it, so thus likely not worth expense to fix.

...

• ~800 cores are used by ~20 people, sometimes running 30 programs (at once?).
