# Software-Defined Storage

> Unified block, object, and file storage on commodity hardware — petabyte-scale, self-healing, and multi-protocol with XSDS.

Xloud Software-Defined Storage (XSDS) delivers unified block, object, and file storage
on commodity hardware — scaling from terabytes to petabytes with no single point of
failure. A self-healing architecture continuously monitors and redistributes data to
maintain durability, while multi-protocol access lets applications consume storage
through the interface that suits them best.
