Finally SAS disk shelves from NetApp. Also in a 24 drive configuration.
Update: Looks like these will ship with new systems only starting December (and by new systems, it seems maybe only the FAS-3170s). General availability will come a few months later.
We finally ordered some of these shelves, and they’re quite nice!
