Switched PDUs provide a practical way for IT managers to remotely reboot locked devices and eliminate costly service calls
. They offer the same features as the Metered PDUs, but with the addition of a built-in network interface which allows managers to remotely control power to individual PDU outlets via a network connection. If power does fail, IT administrators can remotely shut down less critical devices in order to redistribute limited backup power.
IT managers have identified several features to increase the efficiency of their data centers including outlet-lever power metering and switching; environmental monitoring, improved user management, and both critical and non-critical thresholds and alerts for both power and conditions.
While technically not very complex, PDUs can dramatically increase a system's power availability and manageability, when selected and deployed properly.
