I just added two DS14 shelves to an F840. I have 24 of the disks available for a new volume(s). Would it be better to create 2 volumes of 12, 72G drives or 1 volume of 24, 72G drives. The filer is used as a cache for storing radiology images. No backups are required and there are no snapshots required either. I have two hot spares available.
