The value 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.

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.

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

Benefits of the OceanStor 9000 InfoEqualizer feature: - Improved service performance: InfoEqualizer can intelligently allocate the received client access requests to less loaded nodes, greatly improving client access performance. - Improved service reliability: InfoEqualizer can automatically detect a faulty node and switch services from the faulty node to other nodes, improving client access reliability. - Reduced maintenance costs: InfoEqualizer allows clients to access OceanStor 9000 using domain names, thereby eliminating the need to use specific IP addresses in each access. This function greatly simplifies management, reducing the management costs.
