Compare the Top Enterprise Software-Defined Storage (SDS) as of November 2025

What is Enterprise Software-Defined Storage (SDS)?

Software-Defined Storage (SDS) is a storage architecture that separates the software control layer from the physical storage hardware, allowing organizations to manage storage resources — like capacity, performance, replication, and provisioning — through a unified software layer rather than being locked into specific hardware arrays. These solutions pool storage across commodity servers or diverse storage devices and abstract them into flexible, dynamic storage services. SDS enables policy-based automation, easier scalability, hardware vendor independence, and rapid provisioning. It supports block, file, and object storage interfaces and is well suited for hybrid cloud, edge, and modern data-driven environments. Ultimately, SDS empowers IT teams to treat storage as a programmable resource, reduce costs, increase agility, and adapt quickly to changing data demands.
