This topic describes how to manage file systems in the Apsara File Storage NAS console. In the console, you can create a file system, view a list of file systems, view the details of a file system, and delete a file system.

Create a General-purpose NAS file system

  1. Log on to the NAS console.
  2. In the File System Selection Guide section of the Overview page, click Create a Common NAS File System.
  3. On the page that appears, set the following parameters.
    Parameter Description
    Billing Method Select a billing method based on your business requirements. Valid values: Subscription and Pay-As-You-Go. For more information, see Billing of General-purpose NAS file systems.
    Region Select the region where you want to create the file system.
    Note
    • If an Elastic Compute Service (ECS) instance and a NAS file system reside in different regions, the ECS instance cannot access the file system.
    • You can create a maximum of 20 file systems in each region by using the same Alibaba Cloud account.
    Zone Each region has multiple isolated locations that are known as zones. The power supply and network of each zone are independent. If an ECS instance and a NAS file system reside in different zones of the same region, the ECS instance can access the file system.

    We recommend that you select the zone where the ECS instance resides. This avoids extra latency that is caused by cross-zone communication between the file system and the ECS instance.

    Protocol Type Select the protocol type of the file system. Valid values: NFS and SMB.

    The Network File System (NFS) protocol is applicable to file sharing among Linux ECS instances. The Server Message Block (SMB) protocol is applicable to file sharing among Windows ECS instances.

    Storage Type Select the type of the file system. Valid values: Performance Type and Capacity Type.

    For information about the performance comparison between a NAS Capacity file system and a NAS Performance file system, see NAS Performance.

    Encryption Type Select the encryption type of the file system. Valid values: None and Encryption. If you select Encryption, keys that are hosted by Key Management Service (KMS) are used to encrypt data in a file system. For more information, see Encrypt data.
    • Encryption is supported only for NFS file systems.
    • Data is automatically decrypted when you access the encrypted data.
    Network Type Select the network type of the mount target. Valid values: VPC and Classic Network.
    • You can create a mount target in the classic network only in a region inside China.
    • You can mount a file system in the classic network only on an ECS instance.
    VPC Select the VPC where you want to create the mount target. If no VPC is available, create a VPC in the VPC console.
    Note We recommend that you select the VPC of the ECS instance on which you want to mount the file system. If the ECS instance and file system reside in different VPCs, you must use Cloud Enterprise Network (CEN) to connect the VPCs. Then, the ECS instance can communicate with the file system. For more information, see Enable a cross-VPC mount for a file system.
    VSwitch Select a VSwitch that resides in the VPC.
  4. Click Buy Now and complete the payment as prompted.
    Note After the file system is created, the default permission group is attached to the mount target. For information about how to modify the permission group of a mount target, see Modify the permission group of a mount target.

Create an Extreme NAS file system

  1. Log on to the NAS console.
  2. In the File System Selection Guide section of the Overview page, click Create a extreme NAS file system.
  3. On the page that appears, set the following parameters.
    Parameter Description
    Billing Method Select a billing method based on your business requirements. Valid values: Subscription and Pay-As-You-Go. For more information, see Billing of Extreme NAS file systems.
    Region Select the region where you want to create the file system.
    Note
    • If an ECS instance and a NAS file system reside in different regions, the ECS instance cannot access the file system.
    • You can create a maximum of 20 file systems in each region by using the same Alibaba Cloud account.
    Zone Each region has multiple isolated locations that are known as zones. The power supply and network of each zone are independent. We recommend that you select the zone where the ECS instance resides.
    Protocol Select the protocol type of the file system. Valid values: NFS and SMB.

    The NFS protocol is applicable to file sharing among Linux ECS instances. The SMB protocol is applicable to file sharing among Windows ECS instances.

    Type Select the type of the file system. Valid values: Standard Type and Advanced Type.
    Capacity Adjust the slider to control the capacity. The capacity ranges from 100 GB to 256 TB.
    Data Encryption Select the encryption method of the file system. Valid values: Not Encrypted, Encryption at Rest, and Custom Key.
    • If you select Custom Key for this parameter, you must create a customer master key(CMK). For more information, see Create a CMK.
    • If you select Encryption at Rest or Custom Key for this parameter, the snapshots of the file system are also encrypted.
    Key ID Select the ID of the CMK. This parameter is required only if you select Custom Key as Data Encryption.
    Duration Select the validity period of the file system. The file system will be suspended when the validity period expires. For more information, see Overdue payments.

    We recommend that you select the Auto-renewal check box. After you enable the auto-renewal feature, the file system is automatically renewed on a monthly basis.

  4. Click Buy Now and complete the payment as prompted.
