Distributed Storage can be configured as a Disk Library using a Commvault MediaAgent.
To setup the disk library you must setup the storage servers and the Commvault MediaAgent which will also act as a Distributed Storage Proxy to move the data to the storage servers.
This documentation uses the following terminology.
Consists of the storage servers (or nodes) which together will act as a repository for the data.
Storage proxy along with Commvault MediaAgent moves the data between the client and the storage servers.
Deployment server is used to deploy the software on storage servers and the proxies.
Determines the method of storing the data.
Protection Policy can be one of the following:
Replication is the simplest form of data protection, which replicates and maintains one or more additional copies of the original objects.
Erasure Coding is a data protection method which duplicates blocks of data across storage media. Erasure coding adds redundancy to the system and tolerates failures without data loss.
