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 ES30 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.
Avamar integrated with Data Domain systems
Integrated Avamar Data Domain solutions are possible for older systems. Figures are
provided showing how these are racked and cabled. The recommended configuration
has the Avamar node in Rack 1 at position U39 in the rack. 10U of space below the
node are left free for Avamar expansion. The ES30 shelves occupying those positions
must be moved; thus the cabling may be very different than a standard configuration.
Avamar is not integrated with the DD6300, DD6800 and DD9300, and DD9500 and
DD9800 systems.
Rail kit
One of each of these items is included with each ES30 shelf.

supports racks with threaded holes. See the document

Systems that are delivered in racks use a slightly different Rail Kit and do not need
the Rail Adapter Kit.
Shelf cabling rules and guidelines
The Data Domain system re-discovers newly configured shelves after it restarts. You
can power down the system and re-cable shelves to any other position in a set, or to
another set. To take advantage of this flexibility, these rules MUST be followed before
making any cabling changes:

Do not exceed the maximum shelf configuration values for your Data Domain
system as listed in the table below.
