The correct order in which the XtremIO X1 cluster components should be powered on for the first time is: PDU (Power Distribution Unit) BBUs (Battery Backup Units) XMS (XtremIO Management Server) Storage Controllers Detailed Explanation with Reference: PDU (Power Distribution Unit): Begin by powering on the PDU to provide power to the entire rack. BBUs (Battery Backup Units): Next, power on the BBUs to ensure power protection for the system. XMS (XtremIO Management Server): Power up the XMS to allow management and monitoring of the storage system. Storage Controllers: Finally, power on the Storage Controllers to bring the storage system online. Reference: Dell XtremIO Installation and Power-Up Guide. Thank you for your visit.
