In an OceanStor 9000 storage system, the calculate quota is set to 50 GB for user A to access the /dir directory. When the amount of data that user A writes exceeds 50 GB in the /dir directory, the system allows user A to continue to write data in the /dir directory.

Based on full interconnection of data channels and communication channels, a clustered NAS system employs cluster volume management to manage global storage space. Specifically, any nodes in a cluster can access the same storage space using the same volume device name, ensuring access consistency.

When configuring an N8500 clustered NAS engine, a user must specify the start and end physical IP addresses and the start and end virtual IP addresses.
