ProLiant Server High-Density Deployment Server Solution

Power Distribution Solutions
HP recommends using power distribution units (PDUs) in installations where the large number of server
units can place serious loading demands on the AC power bus. HP offers PDUs that provide safety
and reliability to multi-server installations.
The PDUs described in this white paper offer 0U and 1U mounting options and feature circuit-breaker
protection of the equipment. The equipment power can be organized in groups to minimize the
impact of power interruption.
Figure 1 shows a PDU using the 0U rack mounting option. HP recommends this configuration in
high-density installations that require the maximum amount of vertical space for servers and other
active components. The 0U configuration offers the following advantages:
• Saves vertical rack space for equipment requiring more operator/maintenance accessibility
• Offers easy access to power connections
