Disk Drive Layouts - HP StoreAll Series Installation Manual

The stabilizing feet are attached to the rack if it is a single-rack installation.
Any adjacent racks are securely coupled together in multiple-rack installations.
Only one component in a rack is extended at a time during installation and operation. A rack
might become unstable if more than one component is extended.
Devices are fully and properly supported and level when sliding them into the rack. Do not
extend the hard drive drawers beyond the supporting surface when the unit is not installed in
a rack.
Follow industry-standard recommendations.

Some items to note about disk drive layouts:
Pools do not span a drive drawer in the MDL SAS capacity block.
Pools do not span enclosures in the ENT SAS capacity block.
All drives in a single MDL SAS capacity block must be of the same capacity.
All drives in a group of ENT SAS capacity blocks (up to 4) must be of the same capacity.
