Introduction
Cloud File Storage (CFS) provides a scalable shared file storage service that can be used with services such as Cloud Virtual Machine (CVM). CFS offers standard NFS file system access protocols to provide shared data sources for multiple CVM instances. It supports elastic capacity expansion and performance scaling. CFS can be mounted on existing applications without modification. As a highly available and reliable distributed file system, CFS is suitable for various scenarios such as big data analysis, media processing, and content management.
CFS is easy to integrate, eliminating a need to adjust the business structure or make complex configurations. To integrate and use CFS, complete three steps only: creating a file system and its mount point, launching a file system client on a server, and mounting the created file system.
Product Features
Integrated Management
CFS supports NFS v3.0/v4.0 protocol and POSIX access syntax (such as strong data consistency and file locking). Users can mount a file system by running the standard mount command on the corresponding operating system.
Automatic Expansion
CFS can automatically expand the storage capacity of a file system based on the file size without interrupting requests and applications during the process, thereby ensuring exclusive use of storage resources while reducing management workload.
Security Settings
CFS features extremely high availability and persistence. Each file stored in a CFS instance has 3 redundant copies. It supports access from VPC and access control.
Pay-as-You-Go
CFS is metered and billed by the actual usage of an instance. It allows multiple CVM instances to share the same storage space via the NFS protocol.
