We recently purchased a number of DS224C shelves that are now mixed in with older DS2246 shelves. Both have 900GB drives populated in them but they're on two different stacks.
We've created seperate aggregates to keep the disks behind the IOM6 and IOM12 apart. Seems it's not a problem to have the disks mixed, but is this recommended? What happens when a drive fails? Is there a way to set some affinity to the correct drive based on the shelf it's a member of?
2 spares from each stack of shelves for each node (8 total)
7 DS224C shelves (IOM12)
5 DS2246 shelves (IOM6)
