What is Software-Defined Storage (SDS) in the USA?

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.

VaultFS

Swiss Vault

VaultFS, developed by Swiss Vault Global, is an advanced data archive solution designed to provide exceptional data robustness, scalability, and efficiency for long-term storage needs. By utilizing erasure coding, VaultFS divides data into fragments with redundant pieces, distributing them across various storage locations to ensure data can be reconstructed even if some fragments are lost or corrupted. This approach minimizes hardware overhead, reducing both initial investments and ongoing maintenance costs. VaultFS's peer-to-peer architecture eliminates single points of failure, and its auto-regeneration mechanisms automatically repair corrupted data, ensuring continuous availability. The system's dynamic configuration allows for seamless scalability by adding more disks or nodes without disrupting operations, making it a reliable and efficient choice for organizations seeking next-generation data storage solutions.
