3-Phase power connections for 40U-P (current racks)
Some environments use 3-phase power for 40U-P racks used for several Data Domain
systems. In those situations it is desirable to balance the current draw across all 3
phases. The recommended 3-phase power cabling attempts to do that, but an optimal
configuration is dependent on the specific installation. The following figures show
recommended 3-phase power connections for several Data Domain systems.
Note
The next few diagrams show recommended 3-phase delta power connections.
