By default, a datagrid repository named zos is automatically created. The datagrid repository represents VMs residing in the PlateSpin Orchestrate datagrid, which is a storage area on the Orchestrate 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 them 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.
