Create a new Hyperdisk volume | Compute Engine Documentation

Stay organized with collections Save and categorize content based on your preferences.

You can use a Hyperdisk Balanced, Hyperdisk Extreme or Hyperdisk Throughput volume with your Compute Engine instance by completing the following tasks:

• Create a blank, non-boot, and zonal Hyperdisk volume and attach it to your instance either during or after instance creation.
• Format and mount the volume to provide access to a data or file system.

For Hyperdisk Balanced volumes, you can also create boot disks as well as data disks.

For general information about Hyperdisk, see About Hyperdisk.

To add a Hyperdisk Balanced High Availability disk to your instance, use the following procedures:

• Create a regional disk
• Create a new instance with regional boot disks

• Review the Hyperdisk limitations before adding a Hyperdisk volume to your compute instance.
• If you haven't already, then set up authentication. Authentication is the process by which your identity is verified for access to Google Cloud services and APIs. To run code or samples from a local development environment, you can authenticate to Compute Engine by selecting one of the following options:

  Select the tab for how you plan to use the samples on this page:

  Console

  When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

  gcloud

  1. After installing the Google Cloud CLI, initialize it by running the following command:

     gcloud init

     If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

     Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
  2. Set a default region and zone.
  Go

  To use the Go samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

  3. To initialize the gcloud CLI, run the following command:

     gcloud init

  4. If you're using a local shell, then create local authentication credentials for your user account:

     gcloud auth application-default login

     You don't need to do this if you're using Cloud Shell.

     If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

  For more information, see Set up authentication for a local development environment.

To get the permissions that you need to add a Hyperdisk volume to your instance, ask your administrator to grant you the following IAM roles on the project:

• Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1)
• To connect to an instance that can run as a service account: Service Account User (v1) (roles/iam.serviceAccountUser)

For more information about granting roles, see Manage access to projects, folders, and organizations.

These predefined roles contain the permissions required to add a Hyperdisk volume to your instance. To see the exact permissions that are required, expand the Required permissions section:

The following permissions are required to add a Hyperdisk volume to your instance:

• To create and attach a Hyperdisk volume:
  • compute.disks.create on the project
  • compute.instances.attachDisk on the instance
  • compute.disks.use on the volume that you want to attach to the instance
• To format and mount the attached volume: compute.instances.setMetadata on the instance

You might also be able to get these permissions with custom roles or other predefined roles.

The size you specify for a Hyperdisk volume must be within the ranges listed in following table.

However, the size of a Hyperdisk volume that's attached to a VM can't exceed the Hyperdisk limits for the VM.

The following table lists the limits for the performance that you can specify for each Hyperdisk type. However, the IOPS and throughput levels you can specify also depend on the volume's size. For a detailed summary of each limit, see the Size and performance limits section for Hyperdisk Balanced, Hyperdisk Balanced High Availability, Hyperdisk Extreme, Hyperdisk ML, and Hyperdisk Throughput.

The following table lists the reference values of each Hyperdisk type. When creating a Hyperdisk volume with the Google Cloud CLI, REST, or the Cloud Client Libraries for Compute Engine indicate the Hyperdisk type to create by providing its corresponding value from the table.

You can create and attach a Hyperdisk volume by using the Google Cloud console, Google Cloud CLI, or REST.

The size, throughput, and IOPS that you specify when creating a Hyperdisk volume must be in the range of supported values.

When you create a Hyperdisk Balanced volume, you can optionally allow multiple instances to access the disk concurrently by creating the disk in multi-writer mode.

1. Go to the VM instances page.

   Go to VM instances

2. Click the name of the instance where you want to add a disk.

3. On the VM instance details page, click Edit.

4. Under the heading Additional disks, click Add new disk.

5. Specify a name for the disk, and optionally add a description. Select Blank disk as the Disk source type.

6. Under Disk settings, choose a disk type from the following list. The values that you specify must be in the range of supported values.

   1. Hyperdisk Balanced. You can also change the default disk Size, Provisioned IOPS, and Provisioned Throughput settings.
   2. Hyperdisk Extreme. You can also change the default disk Size and Provisioned IOPS settings.
   3. Hyperdisk ML. You can also change the default disk Size and Provisioned Throughput settings.
   4. Hyperdisk Throughput.You can also change the default disk Size and Provisioned Throughput settings.

7. Optional: For Hyperdisk Balanced volumes, you can enable attaching the disk to multiple instances by creating the disk in multi-writer mode. Under Access mode, select Multiple VMs read write.

8. Click Save.

9. To apply your changes to the instance, click Save.

1. Use the gcloud compute disks create command to create the Hyperdisk volume.
