Creating block storage volumes by using the UI

{: #creating-block-storage} [comment]: # (linked help topic)

In the {{site.data.keyword.cloud_notm}} console, you can create a {{site.data.keyword.block_storage_is_short}} volume when you create a virtual server instance, or create a stand-alone volume to later attach to an instance. {:shortdesc}

Before you get started, make sure that you created a VPC. {:important}

Create and attach a block storage volume when you create a new instance

{: #create-from-vsi} {: help} {: support}

  1. In the {{site.data.keyword.cloud_notm}} console{: external}, go to Menu icon Menu icon > VPC Infrastructure > Compute > Virtual server instances.
  2. Click New instance.
  3. Follow these instructions to create your virtual server instance.
  4. To create a block storage volume, under Attached block storage volumes, select New block storage volume.
  5. Enter the information described in the Table 1. When finished, click Create volume.
Field Value
Name Specify a unique, meaningful name for your volume, for example, a name that describes your compute or workload function. The volume name can be up to 63 lowercase alpha-numeric characters and include the hyphen (-), and must begin with a lowercase letter. You can later edit the name if you want.
Note: Volume names must be unique the entire VPC infrastructure. For example, if you create two volumes from Gen 1 and Gen 2 compute resources that are in the same account, the same region, and have the same name, a "volume name duplicate" error is triggered.
Profile Select Tiers and select the performance level that you require from the IOPS list. If your performance requirements don't fall within a predefined IOPS tier, select Custom and select an IOPS value within the range for that volume size. Click the storage size link to see a table of size and IOPS ranges.
Auto Delete Enable this feature to automatically delete this volume when the attached virtual server instance is deleted. You can change this setting later on the virtual server details page.
IOPS Select 3, 5, or 10 IOPS/GB for a Tiered profile
Size Enter a volume size in GBs. Volume sizes can be between 10 GB and 2 TBs.
Encryption Encryption with IBM-managed keys is enabled by default on all volumes. You can also choose Customer Managed and use your own encryption key. For prerequistes and steps to set up customer-managed encryption, see Creating block storage volumes with customer-managed encryption.
{: caption="Table 1. Block storage volume values specified when provisioning an instance" caption-side="top"}

A block storage volume is created and attached to the virtual server instance. On the instance details page, the Attached block storage volumes list is updated to show the new volume.

A block storage volume can be attached to only one virtual server at a time. On the block storage volume summary page, you can view details about the virtual server instance by selecting the instance name under Attached instances.

Create a stand-alone block storage volume

{: #create-standalone-vol} {: help} {: support}

You can create a block storage volume independent of virtual server provisioning and attach the volume to an instance later.

  1. {{site.data.keyword.cloud_notm}} console External link icon, go to Menu icon Menu icon > VPC Infrastructure > Storage > Block storage volumes.
  2. Select New volume.
  3. Enter the information in Table 2 to define your new block storage volume.
  4. When finished, click Create volume. You're returned to the Block storage volumes page, where a message indicates that the volume is being created. A second message displays when the volume is created.
  5. To see details of the new volume, select the View resource link in the second message to go to the Volume details page.
Field Value
Name Specify a meaningful name for your volume. For example, provide a name that describes your compute or workload function. The volume name can be up to 63 lowercase alpha-numeric characters and include the hyphen (-), and must begin with a lowercase letter. Volume names must be unique across the entire VPC infrastructure. You can later edit the name.
Resource Group Specify a resource group. Resource groups help organize your account resources for access control and billing purposes. For more information, see Best practices for organizing resources in a resource group.
Tags Specify a tag to organize your resources. A tag is a label that you assign to a resource for easy filtering of resources in your resource list. For more information about tags, see Working with tags.
Location The availability zone in your region, inherited from the VPC (for example, us-south-1). You can select a different availability zone in your region from the dropdown menu.
Size Enter a volume size in GBs. Volume sizes can be between 10 GB - 2 TBs.
IOPS Select IOPS Tiers and then select the tile with performance level you require.
Select Custom to specify a custom IOPS value based on the size of the volume you're creating. Click the storage size link to see a table of size and IOPS ranges. For more information, see Custom IOPS profile.
Encryption Encryption with IBM-managed keys is enabled by default on all volumes. You can also choose Customer Managed and use your own encryption key.

Next steps

{: #next-step-creating-block-storage-vpc}

When you refresh the Block storage volumes page, the new volume appears at the beginning of the list of volumes. If the volume was created successfully, it shows a status of Available. For stand-alone volumes, the Attachment Type column is blank (-). The Action menu (...) at the end of a table row provides a link for attaching a block storage volume to an instance.

You can continue creating more block storage volumes or manage existing volumes.
