Traditional systems with volume quotas are limited to a single storage device—and to a single volume. After setup, volume-level solutions are limited in management flexibility. For example, typical implementations require the management of quotas across different volumes, multiple storage systems, and multiple file systems. This approach creates challenges when making changes to resources, tracking specific users and groups, moving directory structures, or moving data between file systems and volumes. As more storage silos are added, the complexity only increases.
OneFS SmartQuotas helps to eliminate these management challenges. By the virtue of being fully cluster-aware and spanning all nodes, regardless of the cluster size, IT managers can administer SmartQuotas from a single point of view, provisioning storage exactly how they want, and changing quota policy options on demand.
Storage administrators can define named quotas for specific individual users or groups, or they can create default quotas that control disk usage for anyone accessing the cluster.
Administrators can manage storage across their enterprise so that specific users and groups are allowed to see only the storage that they have been provisioned. Hard, soft, and advisory limits can be set across the organization for specific users and groups, and across the various directory structures. Storage administrators can also configure alerts and send email notifications to users to advise them that quota limits are approaching, enforcing hard stops on writes or providing a grace period of several days before enforcing thresholds. When new users need to be added or directory structures need to be changed, SmartQuotas allows IT managers to immediately modify their quota policies, thus easily meeting the changing storage demands of the enterprise.
