Rockstor's underlying Linux distro is CentOS and the supported filesystem is BTRFS. A pluggable Smart Probe mechanism and a growing list of smart probes provide detailed on-demand information about the various aspects of storage infrastructure. Rockstor supports advanced features for businesses of all sizes ranging from small to large enterprises—for example, snapshots, fast cloning, thin provisioning, dynamic volume management and replication over WAN. The solution comes with a clean, user-friendly Web UI to manage storage operations conveniently.
