Intelligent Power Management (IPM) is used to reduce and optimize electrical power consumption in computer systems and data centers
. IPM systems monitor the temperature of the power supply units, they ensure the correct voltage regulation, current limitation and load distribution
. Modern IPM systems can be monitored and managed by the administrator, which means that unused system components can be switched off to reduce energy consumption. Likewise, any problems that occur can be detected and rectified directly. For example, in the event of a power failure, the uninterruptible power supply (UPS) can automatically take over. Energy costs for cooling can be reduced through temperature monitoring.
