Data Domain DD9300 System Installation and Storage Expansion Guide

Racking and cabling

EMC has adopted recommended racking guidelines.

To provide the best trade-off in terms of serviceability, system expansion, and cabling, mount the controller starting above the first set of shelves in the rack—usually 13U for most systems.

You can connect the 2-meter cable attached to the controller to any shelf in the same rack. Install filler panels in unused rack openings.

After your hardware is installed, route and organize cables by affixing them to the side of the rack to facilitate servicing.

Although you can plan for growth by leaving empty positions in the rack, this method is safe only if the rack is securely bolted to the floor, or if the resulting configuration has a low center of gravity. When in doubt, do not leave empty spaces, and populate based on the guidelines in this section.
