Abstract
Data cache egress of a data storage device (DSD) in a data storage system including a system controller. A size of a reserved space in a memory of the system controller is determined for storing a data cache image for a data cache of the DSD. A loss of power is detected in the data storage system and the data cache image is transferred from the DSD to the system controller. The data cache image is stored in the reserved space in the memory of the system controller.
