Abstract: A method, system, and computer program product are provided. Fan speed is determined for one or more air conditioning unit (ACU) fans and stored to computer memory in response to detecting a request for authorized entrance to the modular data center. ACU fans are adjusted in preparation to deploying retractable baffles that, when deployed, form a temporary vestibule within a space of the modular data center. The retractable baffles are deployed to form the temporary vestibule within the space of the modular data center. Computing resources in the modular data center are shielded from contaminant air that enters the temporary vestibule when the external door is open. The external door is unlocked to allow user entrance to the temporary vestibule. When the external door closes, air is purged from the temporary vestibule. Retractable baffles are retracted. The fan speeds are restored from the computer memory.

Abstract: Disclosed embodiments provide methods, systems, and computer program products for implementing enhanced phase power load balancing of a set of systems (e.g., the set of systems of a data center) using a subset of the systems. Disclosed embodiments extract phase currents of a three-phase power source of the set of systems, and determine, based on extracted phase currents for the set of systems, input phase power load balancing for the subset of the systems.

Abstract: A system and related method balance phase power in a power distribution system. The method comprises performing the following operations dynamically and repeatedly, during operation of subcomponents receiving power from a plurality of redundant intelligent PDUs. Input phases of the intelligent PDUs are monitored for power values associated with the input phases that provide power to the subcomponents through the PDUs. A target per-phase power value is determined. When the input phases are not balanced, an input phase at an input port is redirected to an output port of at least one of the PDUs using a switch to bring the not-balanced phases closer to being balanced phases by reducing a difference of phase powers to the target per-phase power value. The method then comprises performing load shifting on the power supply units (PSUs) associated with the redundant PDUs to improve an overall phase power balance across all redundant PDUs.
