It's part of the watchdog bios. So if the bad drive fails it tries the next one, etc till all drives fail or till it finds one that boots. The OS uses 10gig of HD space off each drive. You will need to see how much Snapshot space you need. Do not make this any larger than what you thing you will need. This takes away from your storage space.
If you cold boot the Guardian only copies the OS over. If you hot swap it will auto transfer the OS and start resync of the array. Hot swap is the prefered method if you have a HD failure.
If you have that may to do you will be a pro by the time you finished.
I hope you bought the WD Raid Edition HD's for your snaps. Being 320gig that is the largest WD makes. These drives preform super. I have a habit of running SpinRite on all new HD's that I put in service. MFG no longer scan for HD defects. Doing this before putting them on line ensures you will not have any delays that will effect the array stability. All of my WD RE drives have always been super clean. Can't say that about the last Seagates I bought.
Any more questions just ask. Andy is the hardware person for this forum (snap) and other computer related hardware. Andy allways calls me the software guy, but by school is hard knocks process. But I did di some extensive testing on the recovery procedures of the Guardian Units. As long as you make a diaster recovery files and 1 set of snapshots, (back up to another server) it will be very hard pressed to fail them. I would recommend failing a drive to see how the process works.
