The controller in an intelligent storage system is responsible for various management functions, including replication and storage management. It acts as the brain of the storage system, coordinating data storage, retrieval, and replication processes to ensure data availability and integrity. Controllers manage both hardware components (such as disks and solid-state drives) and software functions (like data deduplication, compression, and RAID configuration). By managing replication, the controller ensures that data copies are maintained across different storage arrays or locations, providing redundancy and facilitating disaster recovery.
