Software-Defined Storage (SDS) is a technology that separates storage hardware from the software that manages it. This allows organizations to use various types of storage devices, such as hard drives and solid-state drives, while controlling them through a unified software interface. SDS enhances flexibility and scalability, making it easier to adapt to changing storage needs. With SDS, businesses can automate storage management tasks, optimize resource allocation, and reduce costs. It also supports features like data replication and backup, ensuring data availability and protection. Overall, SDS simplifies storage management and improves efficiency in data handling.
