- Set Up the Switches

## Hardware Readiness

Validate that the Commvault Grid hardware meets the deployment requirements and is configured correctly.

- Set Up the Hardware

## CommServe Connectivity Readiness

Complete the following tasks only if you are deploying Commvault Grid into an existing CommServe environment.

### Verify CommServe Compatibility

Ensure that the CommServe version is compatible with the Commvault Grid software version.
