Help Center/ Elastic Volume Service/ Getting Started/ Quickly Purchasing and Using an EVS Disk

Quickly Purchasing and Using an EVS Disk

Updated on 2024-10-10 GMT+08:00

Scenarios

  • When you purchase a server, the system disk is automatically added. You do not need to buy the system disk separately. Data disks can be purchased together with a server or later separately. If you add data disks during the server purchase, the system will automatically attach the data disks to the server. If you buy data disks after the server is purchased, you need to manually attach the data disks.
  • After a data disk is attached to a server, you must log in to the server and initialize the disk before you can use the disk.
  • System disks are initialized automatically. You only need to initialize data disks.

Procedure

  1. Log in to the EVS console.

    1. Log in to the management console.
    2. Choose Storage > Elastic Volume Service.

      The Elastic Volume Service page is displayed.

    3. Click Buy Disk.
      NOTE:
      • An EVS disk can only be attached to a server in the same AZ.
      • After a data disk is attached to a server, you must log in to the server and initialize the disk before you can use the disk.

  2. Buy a disk.

    1. Set Region, AZ, Attach to Server, Billing Mode, and Data Source.

      ① Select a billing mode, region, and AZ. In this example, select Pay-per-use for Billing Mode and select the region and AZ based on the site requirements.

      ② Select a data source. In this example, select a snapshot of disk A to create disk B.

      NOTE:
      • An EVS disk can only be attached to a server in the same AZ.
      • EVS disks can be created empty or from a data source.
    2. Select a disk type and specify a disk capacity.

      ① Select a disk type. In this example, select Ultra-high I/O.

      2. Specify a disk capacity. In this example, specify 100 GB.

      NOTE:
    3. Configure advanced settings and automatic backup.

      1. Determine whether to use automatic backup. In this example, select Buy new, enter 100 GB for the vault capacity, and use the default backup policy.

      2. Select Share and SCSI. There are two device types: VBD and SCSI. If SCSI is not selected, VBD is used by default. You are advised to select both Share and SCSI. In this example, select Share and SCSI.

      3. Select Encryption. In this example, Select Encryption.

    4. Select an enterprise project and a tag.

      ① Select an enterprise project. In this example, select default.

      2. Select a tag. In this example, select the existing tag test01.

      NOTE:
      • An enterprise project makes it easy to manage projects and groups of cloud resources and users. Use the default enterprise project or create one.
      • You can add tags when creating disks. Tags can help you identify, classify, and search for your disks.
    5. Specify a disk name and purchase quantity.

      ① Enter a disk name. In this example, enter volume-test.

      ② Select a purchase quantity. In this example, buy one disk.

      NOTE:

      If you choose to create disks from a backup or snapshot, batch creation is not supported, and quantity parameter must be set to 1.

  3. Attach a shared disk. (Perform this step if you create a shared disk.)

    1. In the disk list, locate the disk and click Attach.
    2. On the displayed page, select the servers you want to attach the disk and select a function from the drop-down list. The disk and servers must be in the same AZ.
      NOTE:
      • A shared EVS disk can be attached to a maximum of 16 servers.
      • If you simply attach a shared disk to multiple servers, files cannot be shared between the servers, because the shared disk does not have the cluster capability. To share files between servers, build a shared file system or deploy a cluster management system.

  4. Attach a non-shared disk. (Perform this step if you create a non-shared disk.)

    1. In the disk list, locate the disk and click Attach.
    2. On the displayed page, select the server you want to attach the disk and select a function from the drop-down list. The disk and server must be in the same AZ.
      NOTE:
      • A non-shared disk can be attached to one server only.
      • After the disk is attached to a server, you must log in to the server and initialize the disk before you can use the disk.

  5. Initialize the data disk. (Perform this step if you create a non-shared disk.)

    1. Log in to the server.
    2. Initialize the disk.
