What Is SFS?

Scalable File Service (SFS) is a network attached storage (NAS) service that provides scalable high-performance file storage. With the service, shared access can be achieved among multiple Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and containers created on Cloud Container Engine (CCE) and Cloud Container Instance (CCI). See Figure 1.

Compared with traditional file sharing storage, SFS has the following advantages:
  • File sharing

    ECSs in multiple availability zones (AZs) of a same region can access the same file system concurrently and share files.

  • Elastic scaling

    Storage can be scaled up or down on demand to dynamically adapt to service changes without interrupting applications. You can complete resizing with a few clicks.

  • Superior performance and reliability

    The service enables file system performance to increase as capacity grows, and delivers a high data durability to support rapid service growth.

  • Seamless integration

    SFS supports NFS and CIFS protocols. With these standard protocols, a broad range of mainstream applications can read data from and write data in the file system. In addition, the service is compatible with SMB 2.0, SMB 2.1, and SMB 3.0, facilitating Windows clients to access the shared space.

  • Easy operation and low costs

    In an intuitive graphical user interface (GUI), you can create and manage file system with ease.
