I am wondering how one might go about designing a storage space for a large number of drives. Specifically I've got 45 x 4TB drives. As i am not extremely familiar with storage spaces, i'm a bit confused as to how I should go about designing this. Here is how i would do it in hardware raid and i'd like to know how to best match this setup in Storage Spaces. I've been burned twice now by poorly designed storage spaces and i don't want to get burned again. I want to make sure if a drive fails, i'm able to properly replace it without SS tossing it's cookies.
In the hardware raid world, i would divide these 45 x 4TB drives into three separate 15 disk Raid 6's. (Thus losing 6 drives to parity) Each raid 6 would show up as a separate volume/drive to the parent OS. If any disk failed in any of the three raids, i would simply pull it out and put a new disk back in and the raid would rebuild itself.
Here is my best guess for storage spaces. I would create 3 separate storage pools each containing 15 disks. I would then create a separateDual Parity Virtual Disk for each pool. (Also losing 6 drives to parity) Each virtual disk would appear as a separate volume/disk to the parent OS. Did i miss anything?
Additionally, is there any benefit to breaking up my 45 disks into 3 separate pools? Would it be better to create one giant pool with all 45 disks and then create 3 (or however many) virtual disks on top of that one pool?
