The RESTful API method used to retrieve an existing configuration from an XtremIO system is the HTTP GET methD. This is a standard method used in RESTful APIs for retrieving resources. In the context of XtremIO, the GET method would be used to call endpoints that return information about the system’s configuration. For example, a GET request to /api/json/v2/types/clusters would retrieve information about the clusters1. The Official Dell XtremIO Deploy Achievement document will contain specific details on the API calls and should be referred to for the most accurate instructions.

The correct sequence of steps to create a Windows volume backup using the Microsoft VSS Framework with an XtremIO cluster is as follows:

Requestor interacts with the VSS service to start the backup.

VSS service sends a Freeze request to the Writer.

Provider creates an XVC of the file system and exposes the volume to the host.

VSS service sends a Thaw request to the Writer.

Requestor uses the XVC to back up the content of the volume.

The Requestor, typically a backup application, initiates the process by interacting with Microsoft’s Volume Shadow Copy Service (VSS) to commence a snapshot backup.

The VSS service then issues a Freeze request to its Writers, which are responsible for ensuring data consistency for applications during backups.

An XtremIO Provider, which interfaces between the XtremIO storage and VSS, creates an XtremIO Virtual Copy (XVC) of the file system. This copy is then made accessible to the host system for backup purposes.

After the XVC is created, the VSS sends a Thaw request to the Writers, allowing them to resume normal operations while maintaining data integrity.

Finally, the Requestor uses the XVC to back up the content of the volume, ensuring a consistent and recoverable backup is made.

Please note that this sequence is based on the standard operation of Microsoft VSS with storage systems like XtremIO and should be verified against the most current Dell XtremIO Deploy Achievement documentation for any updates or specific instructions related to your environment.

Zoning: Zoning is the process of configuring which devices can communicate with each other on a storage network.

VPLEX and XtremIO: The first step in adding an XtremIO cluster to a VPLEX environment is to zone the VPLEX to the XtremIO Storage Controllers.

Initial Configuration: This step ensures that the VPLEX can recognize and communicate with the XtremIO storage, which is necessary before proceeding with other configurations.
