Abstract:
An energy storage device included in a data center environment can supply energy to a set of solid state drives in the data center environment when power failure or another power event has occurred. In some embodiments, there can be a controller for each solid state drive. The controller can be configured to detect or determine the occurrence of the power failure or other power event and, in response, transmit a command to a respective solid state drive instructing the solid state drive to perform a graceful and atomic shutdown operation, so that data stored on the drive is made durable and the drive enters a quiescent state (e.g., sleep mode, hibernate mode, power-off mode, etc.). As such, the energy storage device can provide protection against power events to solid state drives that lack native (e.g., built-in, inherent, etc.) power protection mechanisms.
