A Power Distribution Unit (PDU) is a piece of hardware with numerous power outlets that distributes electricity to IT equipment in a rack and offers electrical protection. PDUs can be basic (sometimes referred to as "dumb") or intelligent, and intelligent rack PDUs come in a variety of kinds. Intelligent Power Distribution Units include a number of features and abilities over standard PDUs, including metering, remote power control, environmental sensors, firmware upgrades, SNMP trap notifications, and security improvements. In an integrated, single-pane-of-glass interface, data centre infrastructure management (DCIM) software is frequently utilised to improve many of the features and capabilities offered by PDUs. Through business intelligence dashboards and visual analytics, PDU data is automatically transformed into information that can be used for decision-making. The same UI may be used to perform remote administration and power actions, mass firmware updates, configuration cloning, and backup restoration. Various PDUs Available are- Simple PDUs - These are power strips that supply several outlets powering IT equipment in racks with the proper voltage and current. Observed PDUs- a sort of fundamental Power Distribution Unit that visibly displays the local current electric information. PDUs for metered inlet- These PDUs make it simpler to furnish equipment by assisting users in determining power demand and available circuit capacity. Metering at the intake level enables users to determine efficiency measures like power usage effectiveness and prevent overloading the circuits (PUE). PDUs for metered outlets- Metering at the outlet level makes provisioning easier by enabling users to assess levels of power use and rack capacity availability. Such a model's more particular purpose is to assist users in comprehending the actual power usage at the server or device level, enabling efficiency comparisons. As a result, the data centre can assign expenses to particular departments and make good use of its resources. Changed PDUs- The benefits of a metered inlet Power Distribution Unit are also provided by switched PDUs, coupled with control over a single outlet or a group of outlets. An authorised user has the ability to remotely power devices in a particular order. Additionally, it enables them to postpone the power sequence, preventing an inrush of power and extending the life of the equipment. Such a deployment technique is essential in a remote setting since it enables the restarting of servers to bring back services. By enabling the user to turn off devices that are not in use at the time, it can also aid in energy conservation. PDUs with switched racks and outlet metres- This type of model, as its name implies, enables all the switched PDU's capabilities, including authorised operation from a remote location. We only need to understand what Power Distribution Unit stands for in order to describe PDU. A PDU, or power distribution unit, is a device that controls and distributes electricity in data centres. A big power strip without surge protection is the most basic type of PDU. This is made to offer regular electrical outlets for use in a range of settings without the need for monitoring or remote access. For larger projects, a floor-mounted PDU, also known as the Main Distribution Unit, offers an essential management link between the main power source of the building and a range of equipment racks in a data centre or remote site.
