ABSTRACT:
On or more techniques and/or systems are provided for rapidly resuming processing of client requests after a system failure event. Accordingly, during a boot-up process, a storage system, upon detecting a system failure event of the storage system, conditions its system memory to reflect a state of the system memory at a time of the failure by processing client requests or commands stored in a non-volatile operations log. The storage system can resume processing client requests after processing the operations in the nonvolatile operations log and prior to flushing data to storage devices.
