| 1 | file system | A place where files are stored. A file system can be mounted on a compute node by using a mount target. The data and metadata in the file system are stored in the traditional directory tree structure. A file system supports simultaneous access from hundreds of compute nodes for data sharing and highly concurrent read and write operations. |
| 2 | storage plan | A billing method for General-purpose NAS file systems. This billing method allows you to plan your NAS resources and enjoy discounts. |
| 3 | mount | The process to connect a compute node to a NAS file system. After a NAS file system is mounted on a compute node, the compute node can access data in the file system. |
| 4 | mount target | A connection point of a NAS file system in the classic network or a VPC. Each mount target is displayed as a domain name. |
| 5 | permission group | A group that is used to configure the access permissions of a mount target. You can add rules to a permission group to specify the IP addresses and the corresponding read and write permissions on the file system. |
| 6 | Capacity NAS | A type of General-purpose NAS file systems. Capacity NAS file systems are applicable to scenarios that require high cost efficiency and large capacity. |
| 7 | Performance NAS | A type of General-purpose NAS file systems. Performance NAS file systems are applicable to scenarios that require high concurrency and high throughput. |
| 8 | IA storage medium | A low-cost data storage pool for General-purpose NAS file systems. IA storage media are suitable for storing data that is accessed less than three times per month. |
| 9 | Network File System (NFS) | A software protocol that is used to mount a NAS file system on a compute node. The NFS protocol is applicable to Linux clients and most containers. |
| 10 | Server Message Block (SMB) | A software protocol that is used to mount a NAS file system on a compute node. The SMB protocol is applicable to Windows clients and Windows containers. |
| 11 | POSIX-based APIs | A set of standard interfaces that are used to access files in a Linux operating system. You can call the POSIX-based APIs by using a programming language in applications to manage files. |
