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.
Terminology
This documentation uses the following terminology.
|
Storage Servers |
Consists of the storage servers (or nodes) which together will act as a repository for the data. |
|---|---|
|
Storage Proxy |
Storage proxy along with Commvault MediaAgent moves the data between the client and the storage servers. |
|
Deployment Server |
Deployment server is used to deploy the software on storage servers and the proxies. |
|
Protection Policy |
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. |
