I'd like some opinions regarding the ideal disk layout in my most recent build.
I have a 24-bay chassis, 3x drive controllers capable of 8 drives each. and 24x 1TB sata drives. My initial config is 4x vdevs of 6xdrives using 2x drives on each controller in raid-z2. My thoughts are this allows me to upgrade the disks in smaller numbers 6 at a time, also gives me a great deal of redundancy with raid-z2 and using 2x drives per controller I could actually loose an entire drive controller and the system would remain viable until I replaced the bad component.
My concern with this layout is it does waste a lot of storage, out of 24disks I loose 8 to parity drives. I'm torn between redundancy & space, not very concerned about performance.
Appreciate any suggestions or comments,
Truenigma
