Abstract

Provided is a storage system including a plurality of controllers. The storage system adopts a write-once data storage system and can implement high Input/Output (I/O) processing performance while ensuring data consistency when a failure occurs. Before metadata duplication, recovery data including information necessary for performing roll forward or roll back is stored in each controller, and then the metadata duplication is performed. A recovery data storage processing and the metadata duplication are offloaded to a hardware accelerator.
