Aggregate Setup and Disk Size


I have a new shelf of 2TB SATA drives (14 total). I also have a 2 drives left over that are 1TB SATA (So that's 16 total disks). Would it be OK to create two 7 disk aggregates, with each aggregate having one of the 1TB drives mixed with the 2TB drives? The remaining two 2TB drives would be used as hot spares.




It actually doesn't look like this buys me much as far as useable space goes. If I create a 11 disk aggregate w/ all 2TB drives the usable size is 13.1 TB. The two mixed aggregates I was referring to in my first post would be 6.55 TB usable. I think going to go for the one large aggregate to avoid mixing disk sizes.


Don't forget to keep spares.  The 1TB cannot act as spares for an AGGR built out of all 2TB disks.
