A method, comprising: selecting an HBA entity that is currently turned on and which is part of a host device, the host device being coupled to a storage array, the host device being configured to read and write data to the storage array; identifying an identifier of the HBA entity; identifying, based on the identifier, a switch that is coupled to the HBA entity via a communications path; identifying one or more other communications paths that span between the host device and the switch; detecting whether a redundancy policy would be violated if the HBA entity were to be turned off, the redundancy policy including at least one rule that specifies a minimum number of active paths that must be present between the host device and the switch at any given time; turning off the HBA entity in response to detecting that the redundancy policy would not be violated.

Improving data center sustainability through dynamic inclusion and elimination of paths

A power supply manager manages power utilization of a first uninterruptible power source and a second uninterruptible power source. A load balancing service retrieves information that is associated with a first power supply unit and a second power supply unit, and determines a first power source state associated with the first uninterruptible power source and a second power source state associated with the second uninterruptible power source. The service may also set the first power supply unit in an active mode based on the first power source state, and set the second power supply unit in a standby mode based on the second power source state. The service may also transition the first power supply unit from the active mode to standby mode, and the second power supply unit from standby mode to the active mode, based on a power imbalance.
