Rack configurations for distributing power to HP ProLiant DL servers
This section describes power distribution configurations for a high-density server system based on HP
ProLiant DL 360 G5 servers. The ProLiant DL 360 G5 is a 1U server that uses an auto-ranging power
supply and supports power redundancy when used in the 1 + 1 power supply configuration option.
These configurations use monitored PDUs and fixed cord extension bars (Figure 8).

Table 3 shows the difference in power requirements of the ProLiant DL360 G5 server when it is used
in two different scenarios. In one scenario, the server is configured and utilized to about half its
potential. In the other scenario, the server is nearly at maximum configuration and estimated to run at
a relatively high (70 percent) state of use. Both configurations employ redundant power (two supplies
per system) and use high-line voltage. The maximum configuration operates off three-phase power.
Although a standard 42U rack can physically accommodate 42 ProLiant DL360 G5 servers, it is
advisable to leave space for server expansion, power distribution components such as PDUs and
UPSs, keyboard/video/mouse (KVM) equipment, and/or networking components.
