Abstract
A method of providing a power failure warning in a storage system includes partitioning early power off warning (EPOW) control logic of a storage enclosure to be symmetric with a power distribution network power domain. A power failure warning system for a storage system having a plurality of storage enclosures includes a power system control module coupled to a power supply for control and management of input power to the storage system. An output stage of the power supply is dedicated to a first virtual storage enclosure within one of the plurality of storage enclosures.
