Sample power distribution solutions

This section includes examples for implementing power distribution methods for various rack

configurations. These configurations are examples only. Numerous configurations may be appropriate

depending on factors mentioned earlier such as:

• Server power consumption

• Server configuration (number of processors, hard drives, expansion cards, etc.)

• Server utilization

• Redundant/non-redundant requirements

NOTE

These sample configurations do not take into account

battery backup (UPS) considerations.

Rack configurations for distributing power to HP BladeSystem c-Class

servers

This section describes power distribution configurations based on the HP BladeSystem c-Class system

using the HP BladeSystem c7000 Enclosure and modular or monitored PDUs (Figure 7). The HP

BladeSystem c7000 Enclosure uses auto-ranging power supplies and supports redundant power

supply configurations. Up to four BladeSystem c7000 enclosures can be installed in a standard 42U

rack.
