Overview
CFS user quota is a resource management feature for data management involving multiple users. It enables you to set capacity quotas and file count quotas for users and user groups as needed, addressing capacity allocation among multiple users and user groups and improving the overall resource utilization of the system.
Use cases
Allocating storage space among multiple departments/tenants
Different capacity usage limits need to be set for different end users to meet resource allocation or budget requirements. You can assign users and user groups to actual users, and allocate them resources using the user/user group quotas, enabling more efficient use of storage resources.
Strengths
User-specific capacity quota and file count quota
The user-specific capacity quota enables you to precisely allocate the storage capacity available to a user.
The user-specific file count quota enables you to restrict the usage of inode in the file system by a user, preventing them from saving too many small files that adversely affect the entire system.
User group-specific capacity quota and file count quota
The user group-specific capacity quota enables you to precisely allocate the storage capacity available to a user group. It is suitable for capacity and budget management in a multi-layer organization.
The user group-specific file count quota enables you to restrict the usage of inode in the file system by a user group, preventing them from saving too many small files that adversely affect the entire system.
