Simplify Power Management VSPEX enables customers to deploy a proven infrastructure faster, without the risk and complexity of the traditional build-your-own approach. A power management system from Eaton—consisting of a power distribution unit (PDU), uninterruptible power systems (UPS), and IPM software—seamlessly integrates into VSPEX to monitor and manage power in the data center; measuring power consumption to help calculate power usage effectiveness (PUE), and triggering live migration of virtual machines and graceful shutdown initiation during extended power outages.
