# Storage Class: SMB v3 or later versions These are the fields you must complete to create a new SMB v3 (or later) Storage Class. Fields with an asterisk are mandatory.

Field	Description
*NAME ()**	Assign a Name to the Storage Class. A maximum of 128 characters is allowed.
DESCRIPTION	Enter the description of the Storage Class.
*LOCATION TYPE ()**	The location where files are stored. Choose SMB v3.
*HOST ()**	Remote host IP Address or hostname.
*PORT ()**	Port to connect to the remote host (1 to 65535).
*USERNAME ()**	Username to be used for the connection. The maximum number of characters is 320.
*PASSWORD ()**	User password.
*DOMAIN ()**	User domain.
*SHARE NAME ()**	Name of the share to be mounted.
*BUFFER SIZE ()**	Size of the buffer to be used when reading/writing data. Default value: 1 MB.
*INTERNAL FILES LOCATION ()**	Enter the physical path where INTERNAL files must be saved. The path must start with "/". If omitted, the system automatically adds it.
*EXTERNAL FILES LOCATION ()**	Enter the physical path where EXTERNAL files must be saved. The path must start with "/". If omitted, the system automatically adds it.
*TEMPORARY FILES LOCATION ()**	Enter the physical path where incoming external files are temporarily saved before their transfer is completed. The path must start with "/". If omitted, the system automatically adds it.
CLUSTER	Select the cluster you want to associate with the Storage Class.
SYMMETRIC KEYS	Select the Symmetric Key to associate with the Storage Class. The Symmetric Key displayed in the drop‑down menu must have been created in Setup → Key Store → Symmetric keys. The selected Symmetric Key is used to encrypt the files that are stored using this specific Storage Class. If the option is read‑only, one or more files are already associated with the Storage Class. The Storage Class must be empty in order to associate a Symmetric Key.
CONFIGURATION TEST	Use this section to validate whether the remote Storage Class is correctly configured and fully usable by Data Mover on a specific Cluster. Choose the Cluster on which you want to validate the Storage Class configuration. If only one Cluster is available, it is selected automatically. Click TEST to start the validation process. Each action is displayed with a status icon: ✅ Green check: the action completed successfully. ❌ Red error icon: the action failed and cannot be performed. Hovering over an action displays a tooltip with detailed diagnostic information. Warning: We recommend choosing a remote Storage Class that can sustain all actions listed in this test.

Once you have created the Storage Class, press **Save** and your Storage Class will appear in the Result list. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.primeur.com/data-mover-1.21/virtual-file-systems/storage-classes/storage-class-smb-v3-or-later-versions.md?ask= ``` The question should be specific, self-contained, and written in natural language.
