System Requirements for File Storage Optimization

Verify that your environment meets the system requirements for File Storage Optimization.

  • Index Store

  • Index Gateway

Access Nodes

In File Storage Optimization, the MediaAgent acts as the access node.

  • If you are analyzing data that is not backed up and the operating system of the data source differs from the operating system of the Index Server, then the operating system of the access node must match the operating system of the data source and must have a Commvault package installed. For example, if you want to analyze a UNC share, but the Index Server is on a Linux computer, you must use a Windows computer as the access node.
