Application Scenario

Application scenarios of file systems.

  • VM: File systems apply to VMs. After this scenario is selected, the system will set the block size of file systems to 8 KB, and automatically adjust system resources to adapt to this scenario.
  • Database: File systems apply to databases.
  • User Defined: In this scenario, users need to manually specify the block size of file systems.

File System Block Size

If Application Scenario is set to User Defined, this parameter needs to be specified.

Data in the file system consists of fixed-length blocks. The size of the blocks (also known as file system block size) affects disk space usage and performance. You are advised to configure the block size following the principles below.

  • Select 16 KB when the size of most files in the file system is smaller than 100 KB, the data deduplication or data compression function will be enabled, or the file size and scenarios are not specified.
  • Select 32 KB when the size of most files in the file system is between 100 KB and 1 MB.
  • Select 64 KB when the size of most files in the file system is larger than 1 MB or the file system mainly processes bandwidth-consuming large I/Os (in scenarios such as Media & Entertainment (M&E) industry, and archive and backup of large files).

For details about the file system parameters, refer to "Creating a File System" in this document.
