Meaning of the OceanStor 9000 InfoAllocator feature's hard threshold

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.

The maximum number of quotas that can be created is 8192.

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.
