What Is SFS?

Scalable File Service (SFS) provides scalable, high-performance NAS file storage. With SFS, you can enjoy shared file access spanning multiple Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and containers created on Cloud Container Engine (CCE), as shown in Figure 1.

Compared with traditional shared file storage, SFS has the following advantages:

• File sharing

  Cloud servers in multiple availability zones (AZs) of the 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

  File system performance increases as capacity grows. SFS can support rapid service growth while ensuring a high data durability.

  The background storage system supports the HDD and SSD storage media. It adopts a distributed architecture and uses fully redundant module designs, eliminating single-node faults.

• Seamless integration

  SFS supports the Network File System (NFS) protocol, through which a broad range of applications can read data from and write data to the file system.

• Easy operation

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

You can access SFS on the console or through APIs by sending HTTPS requests.

• APIs

  Use APIs if you need to integrate SFS into a third-party system for secondary development. For detailed operations, see Scalable File Service API Reference.

• Console

  Use the console if you prefer a web-based UI to perform operations.
