Cloud Storage Gateway:Manage SMB shares

Create an SMB share

1. In a browser, enter https://<IP address of the file gateway> to access the on-premises file gateway console.

2. Enter your username and password and click Confirm.

3. Select SMB and click Create.

4. In the Create SMB dialog box, specify the following configuration.

   Parameter	Description
   Share Name	The name of the SMB share.
   Read-only Users	The list of users who have read-only access to the SMB share.
   Read/write Users	The list of users who have read and write access to the SMB share.
   Enabled	Enables the SMB share. To temporarily disable this SMB share, select No.
   Discoverable	Specifies whether the share can be discovered in Network Neighborhood.
   Data Access Mode	Includes cache mode and replication mode. Replication Mode: All data is saved in two copies. One copy is stored in the local cache and the other is stored in Object Storage Service (OSS). Cache Mode: The local cache stores all metadata and frequently accessed user data. The full data is stored in OSS.
   Enable Reverse Sync	Synchronizes metadata from OSS back to the local gateway. This is suitable for disaster recovery, data restoration, and data sharing scenarios. Note During a reverse synchronization process, the system scans all objects in the bucket. If the number of objects is large, you are charged for OSS API calls. For more information, see OSS Pricing.
   Bucket Name	Select a created bucket.
   Path Prefix	Enter a subdirectory of the bucket. The subdirectory name can contain only letters and digits. Note Starting from version 1.0.38, you can map the root directory of the file system to a subdirectory of an OSS bucket for access isolation. The subdirectory can be an existing directory or a new directory in the OSS bucket. After the share is created, this subdirectory serves as the root directory. All subsequent files and folders are created in this directory.
   Use Metadata	Separates the data disk from the metadata disk. The metadata disk is used to store metadata of the shared folder. If you select Yes, select the corresponding Metadata and Data. If you select No, select the corresponding Cache Disk Path. Note Only users on the whitelist can use this feature.
   Ignore Delete	File deletion operations are not synchronized to OSS to prevent accidental deletions. The full data is retained in OSS.
   Sync Delay	Set a Sync Delay. After a file is closed, the upload is delayed for a period of time. This prevents frequent local modifications from causing OSS fragmentation. The default value is 5s and the maximum value is 120s.
   Max Write Speed	The maximum write speed is 1280 MB/s. The default value is 0, which indicates that the speed is not limited.
   Max Upload Speed	The maximum upload speed is 1280 MB/s. The default value is 0, which indicates that the speed is not limited. Note If you limit the speeds, the maximum upload speed cannot be less than the maximum write speed.
   Optimize Fragments	For applications that perform frequent random small I/O reads and writes, enabling this setting can improve performance. Select this option with caution based on your scenario.
   Fast Cache Reclaim	Real-time cache reclamation. This is suitable for scenarios where data is backed up to the cloud.

About AD

Active Directory (AD) is a directory service that uses a standard application protocol to access and change directory data in an Internet Protocol (IP) network.

• You can join an AD domain only after you configure the DNS server.

• Only one type of user, either an AD domain user or a local user, can be active at a time. When you join or leave an AD domain, the user permissions configured for the SMB share are automatically deleted.

• The AD feature supports the 64-bit Windows Server 2016 Datacenter and Windows Server 2012 R2 Datacenter editions.

Configure AD

1. Set up the DNS server.

   1. In the on-premises gateway console, click About.

   2. In the Network Configuration section, click Update DNS.

   3. In the Update DNS dialog box, add a DNS server and click the Confirm button.

      In the DNS Server field, enter the IP address of the AD server that parses the AD domain name.

2. Join an AD domain.

   1. Select SMB > AD.

   2. In the Windows AD section, click Join AD.

   3. In the Join AD dialog box, configure the following settings and click OK.

      • Server IP Address: Enter the IP address of the AD server.

      • Username: Enter the username of the administrator.

      • Password: Enter the password of the administrator.

      After the connection is established, the Connected parameter in the Windows Active Directory (AD) section changes to Yes.

      Note

      • After you join the AD domain, the local user permissions configured for the SMB share are removed.

      • CSG does not support multiple AD domains for a gateway. For example, you can configure either a parent domain or a child domain for a gateway, but not both.

Add an SMB user

1. In the on-premises gateway console, select SMB > SMB Users.

2. Click Create.

3. In the Add SMB User dialog box, set the name and password.

4. Click OK to finalize the creation.
