Abstract
A method for protecting data in a storage system is disclosed. In one embodiment, such a method includes detecting, by a first rack power controller, first battery-on status associated with a first uninterruptible power supply. The method further detects, by a second rack power controller, second battery-on status associated with a second uninterruptible power supply. The method communicates, from the first rack power controller to the second rack power controller, the first battery-on status. The method then triggers, by the second rack power controller, a dump of modified data from memory to more persistent storage upon detecting both the first battery-on status and the second battery-on status. A corresponding system and computer program product are also disclosed.
