Managing General-Purpose File System Tags

Constraints

• A tag is composed of a key-value pair.
  • A tag key can contain a maximum of 128 characters. It can contain letters, digits, and spaces representable in UTF-8 and special characters (_.:=+-@). It cannot start or end with a space and cannot be left empty. Tag keys starting with _sys_ are system tags, and you cannot start a tag key with _sys_.
  • A tag value can contain a maximum of 255 characters. It can contain letters, digits, and spaces representable in UTF-8 and special characters (_.:=+-@) and can be left empty. It cannot start or end with a space.
• You can add a maximum of 20 tags to a general-purpose file system.
• Tag keys of the same general-purpose file system must be unique.

Scenarios

Tags help you to identify your cloud resources. When you have many cloud resources of the same type, you can use tags to classify them by dimension (for example, by purpose, owner, or environment) for usage or cost analysis.

In SFS, you can use tags to identify and classify file systems.

If you add tags to a file system, the bills generated for this file system will contain these tags. You can activate the tags and classify bills by tag for cost analysis.
