Abstract
A technique for managing data within a data storage system involves performing data storage operations on behalf of a set of hosts (i.e., one or more hosts) using a volatile-memory storage cache and a set of magnetic disk drives while the data storage system is being powered by a primary power source (e.g., a main power feed). The technique further involves receiving a power failure signal (e.g., from a sensor) indicating that the data storage system is now being powered by a backup power source rather than by the primary power source (e.g., due to a loss of the main power feed, due to a failure of a power converter, etc.), and moving data from the volatile-memory storage cache of the data storage system to a flash-based memory vault of the data storage system in response to the power failure signal.
