+Any Virtuozzo Storage includes three components:
 * Metadata server (MDS). MDSs manage metadata, like file names, and keep control over how files are split into chunks and where the chunks are stored. They also track versions of chunks and ensure that the cluster has enough replicas. An MDS can be run in multiple instances to provide high availability. Besides, MDSs keep a global log of important events that happen in the cluster.

 * Chunk server (CS). A CS is a service responsible for storing real user data chunks and providing access to these data. A Pstorage cluster must have multiple instances of CSs for high availability.
-* Clients. Clients access a Pstorage cluster by communicating with MDSs and CSs. Parallels Containers and virtual machines can be run natively, i.e. directly from the Pstorage cluster. An additional Pstorage client -  can be used to mount Pstorage as a conventional file system (though Pstorage is not POSIX-compliant).
