By default, a Datagrid Repository named zos is automatically created. The Datagrid Repository represents VMs residing in the ZENworks Orchestrator Datagrid, which is a storage area on the Orchestrator Server.
The zos Datagrid Repository has a location of grid:///vms, which points to an area in the Datagrid reserved for VM archival storage.
You can store VMs to the Datagrid and deploy to a VM host as necessary.
The Datagrid Repository storage is archival because VMs cannot be run from the Datagrid Repository. You must move VMs out of the DataGrid to a VM Host in order to run them.
