1. For **Configure Tag Settings**, review the tags for this module and modify them as necessary. By default, this module uses tags defined in the main solution stack.

1. Choose **Next**.

1. On the **Review** page, verify all the parameters that you provided and choose **Deploy Module** if you confirm that they are correct. The status of the storage shows as **Enabling in progress**. The deployment of this module takes approximately 30 minutes. After the deployment is complete, the status of the Storage module shows as **Enabled**.

1. Follow the [manual configuration steps](manual-configurations.md) in the guide or you can follow the instructions by clicking the **View** button on the MCS Web UI to complete the manual configuration.

1. On the **Review** page, verify all the parameters that you provided and choose **Deploy Module** if you confirm that they are correct. The status of the storage shows as **Enabling in progress**. The deployment of this module takes approximately 10 minutes with no Data Repository Association, and approximately 20 minutes if you specify an S3 Path for Data Repository Association. After the deployment is complete, the status of the Storage module shows as **Enabled**.

1. Follow the [manual configuration steps](manual-configurations.md) in the guide or you can follow the instructions by clicking the **View** button on the MCS Web UI to complete the manual configuration.

**Note**  
MCS deploys a SCRATCH filesystem and does not automatically create a backup when the module is disabled. However, if a Data Repository Association is deployed, data is bidirectionally synchronized between S3 and Lustre, and the data remains in S3 after module disablement.
