2007 mercury upgrade

This was actually done as 2008-10 mercury upgrade

2007-06: Immediate problem: we are running out of disk space on mercury

Option A: External Disk Enclosure

Need:

• SCSI Cable
• SCSI Disk Enclosure
• Two SCSI Disks

Option B: Upgrade One Disk

Replace one of the internal 18s with a 36 or more.

Advantages: most disk for the $

Disadvantages: no mirroring (however we don't have it now anyway.)

Option C: Upgrade Both Disks

Replace both internal 18s with 72s and mirror them.

Advantages:

• will upgrade available data space from 18G to about 54G which will last for a long time
• very safe upgrade path:
  • replace data disk with empty 72G
  • copy boot disk over to new 72 and make it bootable
  • boot from 72, patch and upgrade
  • copy mercury zone over to new 72
  • pull out the data 18, install the second 72, and mirror onto it

Then Dan can use the spare 18s in the backup disk tower at home.

Option D: Rent Space From Moose

Will require monthly $$
