What is Software-Defined Storage (SDS) for Linux?
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.

DataCore Swarm
DataCore Software
Are you struggling with protecting and providing access to rapidly scaling data sets or enabling distributed content-based use cases? Using tape is cost-effective but data is not instantly accessible; and tape is difficult to manage. The public cloud often presents the challenge of compounding, unpredictable recurring costs, and the inability to meet local performance and privacy requirements. DataCore Swarm provides an on-premises object storage solution that radically simplifies the ability to manage, store, and protect data while allowing S3/HTTP access to any application, device, or end-user. Swarm transforms your data archive into a flexible and immediately accessible content library that enables remote workflows, on-demand access, and massive scalability.
