Quota types of the OceanStor 9000 InfoAllocator feature

OceanStor 9000 InfoAllocator is a resource control technology. It restricts resources (including storage space and file number) available for users or user groups in a directory. InfoAllocator enables OceanStor 9000 administrators to: - Plan storage space or file number consumed by a user or a group in a proper way. - Manage storage space or file number that a user or a group consumes. - Make statistics on and check storage space or file number consumed by a user or a group.

Quota modes of the OceanStor 9000 InfoAllocator feature: - Calculate quota: only monitors storage capacity or file usage. - Mandatory quota: monitors and controls storage capacity or file usage.

Mandatory quota thresholds of the OceanStor 9000 InfoAllocator feature: - Recommended threshold: When the used storage space or file quantity reaches the recommended threshold, OceanStor 9000 does not restrict writes but only reports an alarm. - Soft threshold: When the used storage space or file quantity reaches the soft threshold, OceanStor 9000 generates an alarm but allows data writing before the grace period expires. After the grace period expires, OceanStor 9000 forbids data writing immediately and generates an alarm. You need to configure a soft threshold and grace period at the same time. - Hard threshold: When the storage space or file quantity usage reaches the hard threshold, OceanStor 9000 generates a run log and immediately forbids data writing.

The quota of the OceanStor 9000 InfoAllocator feature is determined by user/user group, directory, and quota type.

After you set quotas for a user and an owning user group, or a directory and a child directory, the quotas are valid for both of them, and the quota that reaches the threshold first takes effect.
