Irecently asked a question about the best way to apply 20 2TB drives in a ZFS pool. I have come up with the following setup (thanks to many helpful suggestions) and would love opinions and suggestions about what I may have missed.
I have two SATA controllers (controller1 & controller2) that have the following disks attached:
My thought was to create the pool using mirror pairs of disks, one disk each from each controller; ie:
- mirror1: disk1 & disk2
- mirror2: disk3 & disk4, etc
The two spare drives would give me some redundancy and also having the mirrors made up of disks from each controller should give me some redundancy as well.
Have I missed anything? Ii feel like I can grow the pool with little fuss by adding mirrored pairs and also more redundancy by added spare pairs.
I feel like this would give me a good balance of speed and redundacy.
Thoughts welcome and appreciated.
