Cloud Storage Gateway:File gateways

Last Updated:Jun 16, 2026

Deploy, configure, and manage on-premises file gateways to efficiently bridge local and cloud storage resources.

Deploy an on-premises gateway console

Before you can use an on-premises file gateway, deploy an on-premises console from an image. This involves downloading and installing the image, configuring network settings, and activating the gateway. For more information, see Deploy an on-premises console for a file gateway.

Manage cloud resources

In the on-premises gateway console, you can bind or unbind cloud resources and test connection speeds to ensure seamless data synchronization. For more information, see Manage cloud resources.

Add a disk

To deploy an on-premises file gateway in cache mode, add a disk to the deployment platform, such as VMware vSphere or Hyper-V. You can then configure the disk as a cache disk in the Cloud Storage Gateway (CSG) console or the on-premises file gateway console. For more information, see Add disks.

Note

The minimum cache disk size for a file gateway is 40 GB. If the disk is smaller than 40 GB, the file gateway cannot detect it.

Manage cache disks

In the on-premises gateway console, you can add, delete, and speed-test cache disks for on-premises file gateways. For more information, see Manage cache disks.

Manage NFS shares

NFS shares are suitable for data access from Linux clients. You can create, modify, disable, and delete NFS shares in the on-premises gateway console. For more information, see Manage NFS shares.

Manage SMB shares

SMB shares are suitable for data access from Windows clients. You can create, modify, disable, or delete SMB shares, configure Active Directory (AD) or LDAP settings, and add SMB users in the on-premises gateway console. For more information, see Manage SMB shares.

Access shares

You can access a share by using its network path or by mapping it as a network drive. For more information, see Access shares.

Manage logs

You can upload logs in the CSG console for troubleshooting and performance optimization. For more information, see Manage logs.

Monitor gateways

File gateways V1.0.39 and later support log monitoring. You can monitor gateway status, storage usage, and performance metrics such as CPU usage, memory usage, and network traffic. For more information, see Monitor gateways.

Update gateways

Update a gateway to the latest version for new features and security patches. For more information, see Update gateways.

Modify the AccessKey ID and AccessKey secret

In CSG V1.6.0 and later, you can modify the AccessKey ID and AccessKey secret in the on-premises gateway console. For more information, see Modify the AccessKey ID and AccessKey secret.
