URI

• URI format

  POST /v1/{project_id}/sfs-turbo/shares

• Parameter description

  Parameter	Mandatory	Type	Description

Request

• Parameter description

  Parameter	Mandatory	Type	Description
  share	Yes	Object	Specifies the SFS Turbo file system information. For details about the parameters, see the description of the share field.

• Description of the share field

  Parameter	Mandatory	Type	Description
  name	Yes	String	Specifies the name of the SFS Turbo file system. The value contains 4 to 64 characters and must start with a letter. This value can contain letters (case insensitive), digits, hyphens (-), and underscores (_), and cannot contain other special characters.
  share_proto	Yes	String	Specifies the protocol of the file system. The valid value is NFS. Network File System (NFS) is a distributed file system protocol that allows different computers and operating systems to share data over a network.
  share_type	Yes	String	Specifies the file system type. The valid values are STANDARD and PERFORMANCE STANDARD: Standard file system, corresponding to the media of SAS disks. PERFORMANCE: Performance file system, corresponding to the media of SSD disks.
  size	Yes	Int	For a common file system, the value of capacity ranges from 500 to 32768 (in the unit of GB). For an enhanced file system where the expand_type field is specified for metadata, the capacity ranges from 10240 to 327680. For details about metadata, see Description of the metadata field.
  availability_zone	Yes	String	Specifies the code of the AZ where the file system is located. For details about the code, see Regions and Endpoints.
  vpc_id	Yes	String	Specifies the VPC ID of a tenant in a region. You can obtain the VPC ID from the console or by following the instructions provided in "Querying VPCs" in .
  subnet_id	Yes	String	Specifies the network ID of the subnet of a tenant in a VPC. You can obtain the network ID from the VPC console or by following the instructions provided in "Querying Subnets" in Virtual Private Cloud API Reference.
  security_group_id	Yes	String	Specifies the security group ID of a tenant in a region. You can obtain the security group ID from the console or by following the instructions provided in "Querying Security Groups" in Virtual Private Cloud API Reference.
  backup_id	No	String	Specifies the backup ID. This parameter is mandatory when you create a file system from a backup. This is not supported by the current version.
  description	No	String	Specifies the file system description. The length is 0-255 characters. This is not supported by the current version.
  metadata	No	Object	Specifies the metadata information used to create the file system. The value consists of one or more key and value pairs organized as a dictionary of strings. For details about the parameters, see the description of field metadata.

• Description of the metadata field

  Parameter	Mandatory	Type	Description
  expand_type	No	String	Specifies the extension type. The current valid value is bandwidth, indicating that an enhanced file system is created. For details about the differences between different types of SFS Turbo file systems, see "Recommended Configurations".
  crypt_key_id	No	String	Specifies the ID of a KMS professional key when an encrypted file system is created. The key ID can be obtained from the console of Data Encryption Workshop (DEW) or by referring to section "Querying the Information About a CMK" in the Data Encryption Workshop API Reference.

• The regions mentioned above are the same region. Currently, cross-region configuration is not supported.
• SFS Turbo will create two private IP addresses and one virtual IP address under the subnet you specified.
• To ensure normal use, SFS Turbo will enable the inbound rules for ports 111, 445, 2049, 2051, 2052, and 20048 in the security group you specified.
• An ECS cannot access file systems on VPCs other than the one where the ECS resides. Make sure that you enter the ID of the VPC when creating a file system to be the VPC where the ECS resides for mounting the file system.
