Functions

This section describes main functions of SFS. You can check if a certain function is available in a region on the console.

NFS Protocol

Network File System (NFS) is a distributed file system protocol that allows different computers and operating systems (OSs) to share data over a network. After the NFS client is installed on each ECS, you can mount the file system to implement file sharing between ECSs. NFS is recommended for Linux clients. For more information, see Mounting an NFS General-Purpose File System to ECSs (Linux).

File System Management

File systems are containers that store files in SFS. You can create, view, and delete SFS file systems. For more information, see File System Management.

Multi-VPC Access

You can configure multiple VPCs for a file system so that ECSs in different VPCs can share the same file system, as long as the VPCs that the ECSs belong to are added as authorized VPCs of the file system or the ECSs are added as authorized addresses of the VPCs. For more information, see Configuring Multi-VPC Access.

Permissions Management

SFS uses IAM for permissions management. You can control the read and write permissions of file systems by granting IAM users fine-grained SFS permissions using IAM custom policies. For more information, see Permissions.

Tag

You can use tags to classify and identify file systems. If you add tags to a file system, the bills generated for this file system will contain these tags. You can classify bills by tag for cost analysis. For more information, see Managing General-Purpose File System Tags.

Monitoring

Cloud Eye is a multi-dimensional resource monitoring service. With Cloud Eye, you can view the file system usage and service running status, and respond to exceptions in a timely manner. For more information, see Monitoring General-Purpose File System Using Cloud Eye.

Replicating Settings of Existing File Systems

SFS allows you to replicate settings from an existing general-purpose file system when creating a new one. The following settings can be replicated: region, AZ, protocol, authorization, and tags. For more information, see Creating a General-Purpose File System.

Enterprise Project

An enterprise project manages multiple resources by category. Resources and projects in different cloud service regions can be classified into one enterprise project. For example, an enterprise can classify resources based on departments or project groups and then put relevant resources into the same enterprise project for management. Resources cannot be migrated between enterprise projects. For more information, see Project and Enterprise Project.
