# Software-Defined Storage

Fixed-capacity hardware appliances buy immutability in vendor-sized increments. What that costs over a refresh cycle, and what changes when the storage layer is software-defined.

vStor - backup storage with immutability protection against ransomware, providing DPX users with secure, efficient data protection without proprietary hardware

A PBBA bundles backup software and storage hardware into one box. What that buys you, what it costs in flexibility, and how it compares to running the same software on your own infrastructure.

Choose Software-Defined Storage (SDS) for flexible, scalable, cost-effective backup with enhanced data protection and immutability. Ideal for diverse IT environments.

Maximize scalability with replication and a scale-out backup repository system for enhanced data protection and storage efficiency.

At the heart of every data protection solution is the backup data repository where the backup data sets and backup catalog with recovery points resides.
