Intelligent PDUs and Intelligent Power Management play an important role within the data centre / enterprise IT environments. Knowing how much power IT equipment is using can assist in identifying equipment that can be powered down, or replaced with more energy efficient equipment. Intelligent PDUs or Power Distribution Units have the ability to be monitored or switched. On an intelligent PDU power monitoring can be of the overall PDU or in some models down to the individual outlet, whilst remote switching enables power to be cycled remotely. Intelligent PDUs can be accessed via TCP/IP and provide power consumption data, this data can often be collected by a power management software package.
