Scale up disks

As your business develops and application data grows, your disk space may become insufficient. In this case, you can scale up disks, including system disks and data disks, for larger disk space. This topic describes disk scale-up, including its limits, billing, and methods.

Background information

About disks

By default, Enterprise Office and General Office cloud computers provided by Elastic Desktop Service (EDS) use ultra disks. Enterprise Graphics, Graphics, and High Frequency cloud computers use Enterprise SSDs (ESSDs). The performance levels (PLs) of the disks are consistent with those in the cloud computer templates. For more information about disks, see Disk categories. If you want to change the PLs of disks, see Change the PL of an ESSD.

Limits

The following limits apply for disk scale-up operations:

  • You can only scale up disks. Disks cannot be scaled down after they are scaled up. We recommend that you properly plan your storage space.

  • Disks can be scaled up only in increments of 10 GiB. The capacity of a system disk can be up to 500 GiB, and the capacity of a data disk can be up to 2,040 GiB.

    Note

    The default maximum capacity of a data disk is 2,040 GiB. To increase the maximum capacity to 65,530 GiB (approximately 64 TiB), submit a ticket.

Billing rules

You are charged a unit price for the additional disk capacity when you scale up the disks of a cloud computer. For more information, see Billable items.

  • Subscription cloud computers: You must pay for the incremental capacity based on the remaining subscription duration.

  • Pay-as-you-go cloud computers: The scale-up immediately takes effect, and you are charged based on the new capacity immediately after the scale-up.

Prerequisites

  • The cloud computer for which you want to scale up disks is in the Running or Stopped state.

  • Your data on the cloud computer is backed up. This prevents data loss in case of scale-up failures. We recommend that you create snapshots for the cloud computer in advance. For more information, see Use snapshots (public preview).

Scale up the disks of a single cloud computer

  1. Log on to the EDS Enterprise console.

  2. In the left-side navigation pane, choose Resources > Cloud Computers.

  3. In the upper-left corner of the top navigation bar, select a region.

  4. On the Cloud Computers page, find the cloud computer for which you want to scale up disks, click the ⋮ icon in the Actions column, and then click Scale Up.

  5. In the Scale Up panel, perform the following operations based on the billing method of the cloud computer:

    Subscription cloud computer
    Pay-as-you-go cloud computer

    1. In the Target Disk Size section, specify the desired capacities for the system disk and data disk, and click OK.

    2. In the message that appears, click OK.

    3. On the Purchase page, click Subscribe and complete the payment.

    1. Specify the desired capacities for the system disk and data disk, and click OK.

    2. In the message that appears, click OK.

    During the scale-up, the cloud computer is in the Upgrading state on the Cloud Computers page. When the status of the cloud computer changes from Upgrading to Running or Stopped (the previous state), the scale-up is complete.

Scale up the disks of multiple cloud computers

  1. In the left-side navigation pane, choose Resources > Cloud Computers.

  2. In the upper-left corner of the top navigation bar, select a region.

  3. On the Cloud Computers page, select the cloud computers for which you want to scale up disks, and choose More > Scale Up in the lower part of the page.

  4. In the Specify Disk Size step on the Scale Up panel, select the billing method used by the cloud computers, select the qualified cloud computers, and then click Next.

    Note

    If you want to scale up disks of multiple cloud computers at a time, make sure that they are on the same billing method. Therefore, if the cloud computers you selected in the previous step have different billing methods, you need to scale up the disks for them separately.

  5. In the Confirm Disk Size step, perform one of the following operations based on your business requirements and click Confirm.

    • Scale up disks at the same time: If you want to scale up the disks of all the selected cloud computers to the same size, select Specify Disk Size and configure the New System Disk Capacity and New Data Disk Capacity parameters.

    • Scale up disks separately: If you want to scale up the disks of all the selected cloud computers to different sizes, specify new sizes for each cloud computer in the displayed table.

  6. In the message that appears, click OK.

  7. (Conditional) If the selected cloud computers are subscription cloud computers, click Subscribe on the Purchase page and complete the payment as prompted.

    During the scale-up, the cloud computer is in the Upgrading state on the Cloud Computers page. When the status of the cloud computer changes from Upgrading to Running or Stopped (the previous state), the scale-up is complete.
