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 parameters. The following table describes the 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
    • We recommend that you select the region of an Elastic Compute Service (ECS) instance on which you want to mount the file system. Otherwise, the ECS instance cannot access the NAS file system. If a mount target of the file system and the ECS instance reside in different regions, you can use Cloud Enterprise Network (CEN) to enable a cross-region mount for the file system. However, the cross-region mount compromises the transfer performance of the file system. For more information, see Mount a file system across VPCs or regions.
    • You can create a maximum of 20 file systems in each region by using the same Alibaba Cloud account.
    Zone Select a zone that resides in the region. Each region has multiple isolated locations that are known as zones. The power supply and network of each zone are independent. If the ECS instance and the 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 General-purpose NAS 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 General-purpose NAS file systems.

    Encryption Type Select the encryption type of the file system. Valid values:
    • None: unenable the server-side encryption feature.
    • NAS-managed key: You can use NAS-managed keys to encrypt each file system.
    • User-managed key(KMS): You can use custom keys that are hosted by KMS to encrypt and decrypt file systems.

    If you select NAS-managed key or User-managed key(KMS), keys that are hosted by Key Management Service (KMS) are used to encrypt data in the file system. Data is automatically decrypted when you access the encrypted data.For more information, see Server-side encryption.

    Network Type Select the network type of the mount target. Valid values: VPC and Classic Network.
    Note
    • You can create a mount target in the classic network only in some regions inside China.
    • You can mount a file system only on an ECS instance if you use a mount target in the classic network. The network type of the ECS instance must be the same as that of the mount target. To mount a file system on an ECS instance in the classic network, you must use a mount target that resides in the classic network. To mount a file system on an ECS instance in a virtual private cloud (VPC), you must use a mount target that resides in the VPC.
    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 mount target and the ECS instance reside in different VPCs, you can use CEN to establish a connection between the VPCs. You can then enable a cross-VPC mount for the file system. For more information, see Mount a file system across VPCs or regions.
    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 the 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 parameters. The following table describes the 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
    • We recommend that you select the region of an ECS instance on which you want to mount the file system. Otherwise, the ECS instance cannot access the NAS file system. If the mount target and the ECS instance reside in different regions, you can use CEN to enable a cross-region mount for the file system. However, the cross-region mount compromises the transfer performance of the NAS file system. For more information, see Mount a file system across VPCs or regions.
    • You can create a maximum of 20 file systems in each region by using the same Alibaba Cloud account.
    • Only Extreme NAS file systems that reside in the China (Hohhot) region support the IPv6 feature.To enable the IPv6 feature for file systems that reside in other regions, .
    Zone Select a zone that resides in the region. 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. This avoids extra latency that is caused by cross-zone communication between the file system and the ECS instance.
    Protocol Select the protocol type of the file system. Extreme NAS file systems support only the NFS protocol.
    Type Select the type of the Extreme NAS file system. Valid values:
    • Standard Type: applicable to scenarios that require high input/output operations per second (IOPS) to process a large number of small files, intensive operations on metadata, low latency, and moderate throughput.
    • Advanced Type: applicable to scenarios that require high IOPS to process a large number of small files, low latency, and moderate throughput. The advanced type uses remote direct memory access (RDMA) networking technology. The latency of read/write operations is reduced and the write performance is improved compared with the standard type.
    Note Each zone supports only one type of Extreme NAS file systems. We recommend that you deploy your business in a zone that supports the advanced type.
    Capacity Adjust the slider to control the capacity. The capacity ranges from 100 GB to 256 TB.
    Encryption Type Select the encryption type of the file system. Valid values:
    • None: unenable the server-side encryption feature.
    • NAS-managed key: You can use NAS-managed keys to encrypt each file system.
    • User-managed key(KMS): You can use custom keys that are hosted by KMS to encrypt and decrypt file systems.

    If you select NAS-managed key or User-managed keys(KMS), keys that are hosted by Key Management Service (KMS) are used to encrypt data in the file system. Data is automatically decrypted when you access the encrypted data.For more information, see Server-side encryption.

    Duration Select the validity period of the file system. The file system will be stopped 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.
