Dynamic File Services leverages Microsoft Network Sharing to provide the merged view of a standard pair to users. See the official Microsoft Windows documentation in the Microsoft TechNet Library for information about how to set up network sharing on the computers where the Service is running.
To see the merged view of the two storage locations in a standard pair, users access the files through a Windows network share that you set up on the pair’s primary path. You can have additional network shares nested above and below the primary path. When a user navigates the file tree by using a share above the primary path, the merged view is shown when the primary folder is opened to access the files in the pair. When a user navigates the file tree by using a share below the primary path, the merged view is automatically shown.
For secure access and authentication, users should access the data in the pair only via the network shares that are set up on the primary path. If users directly access files on the primary path or secondary path, potential issues can arise with duplicate files or with access rights and attributes being out of synchronization between primary and secondary folders.
To avoid these potential conflicts:
Restrict direct access to the primary path and secondary path to administrative activities such as backup and restore.
Use the merged view when changing ACL permissions and attributes for files and folders whenever possible as described in Section 4.15, File and Folder Attributes and ACL Permissions in a Standard Pair.
Remove (or strictly limit access to) network shares for the secondary path.
Do not create nested shares above or below the secondary path.
In a Windows cluster, always use the Windows cluster management tool and not Windows Explorer to manage file shares to folders on shared drives. Otherwise, changes to share information made by using Windows Explorer are lost when these file shares fail over to other nodes in the cluster. Workstations should be in an Active Directory domain to access the cluster-managed file shares.
