Abstract
A method for destaging data from cache is disclosed. In one embodiment, such a method includes maintaining, in cache, modified data to be destaged to persistent storage drives. The method further detects an emergency situation wherein the modified data needs to be promptly destaged to the persistent storage drives. In response to the emergency situation, the method automatically disables artificially-imposed throughput limits associated with the persistent storage drives. The method then destages the modified data to the persistent storage drives without restriction from the artificially-imposed throughput limits. A corresponding system and computer program product are also disclosed.
