number of units installed in the rack. Consideration of the electrical power
consumption rating shown on the nameplate should be used when addressing
these concerns. For more information see Connecting power on page 57.
Racking and cabling
The shelves are 5U (including 1U for the Cable Management Assembly (CMA)) and a
Data Domain controller that supports DS60 shelves are 4U, except for the DD6300,
DD6800 and DD9300, which are 2U. For more information, see your Data Domain
system hardware overview.
Data Domain has adopted recommended racking guidelines.
To provide the best trade-off in terms of serviceability, system expansion, and cabling,
mount the Data Domain controller in the 23U position for the DD4200, DD4500,
DD6300, DD6800, DD7200, DD9300, DD9500, and DD9800 systems.
A 5U space is reserved for the controller in the recommended configurations. This is
to simplify installation and labeling instructions.
You can connect the 3-meter cable attached to the Data Domain controller to any
shelf in the same rack. Install filler panels in unused rack openings.
There are figures showing the various configurations through the remainder of this
document. These are guidelines. Other sections define the rules for different systems.
All rules must be followed but using a recommended configuration may depend on
other restrictions in a specific installation.
After your hardware is installed, route and organize all 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.
