Hi all, learning *much* more about RAID etc now that I'm upgrading from essentially raid 0 across 3 pi's into a new system that has the potential for 13 drive bays (at some point).
As I'm learning, I want to verify I understand (some) of how the interaction of RAID 6 and the 3,2,1 rule can be applied.
I'm perfectly okay with if this idea is wrong, and that's fine.
Assumptions: All raid drives are 1TB, running RAID 6, using 4 drives
3 Copies
- Obviously the first one is RAID 6 1TB, allowing for 2 TB storage, 2TB protection. (HDD)
- Second backup: Should this be *another* RAID 6 node? Or can this be a single 2TB drive (SSD)
- Offsite backup: Similarly, can this be a 2TB drive
Essentially when using 3, 2, 1 rule should we be mimicking RAID? Or is it safe to have these drives be single drives (yes, now we've gone from double redundancy to single point of failure, which is why I'm asking)
Thanks!
