Apparatus, system, and method for graceful cache device degradation
Abstract:
Apparatuses, systems, and methods are disclosed for implementing a cache policy. A method may include determining a risk of data loss on a cache device. The cache device may comprise a non-volatile storage device configured to perform cache functions for a backing store. The cache device may implement a cache policy. A method may include determining that a risk of data loss on the cache devices exceeds a threshold risk level. A method may include implementing a modified cache policy for the cache device in response to the risk of data loss exceeding the threshold risk level. The modified cache policy may reduce the risk of data loss below the threshold level.
