Quotas for Amazon EBS - Amazon EBS

Quotas for Amazon EBS

Your AWS account has default quotas, formerly referred to as limits, for each AWS service. Unless otherwise noted, each quota is Region-specific. You can request increases for some quotas, and other quotas cannot be increased.

To view the quotas for Amazon EBS, open the Service Quotas console. In the navigation pane, choose AWS services and select Amazon Elastic Block Store (Amazon EBS). To request a quota increase, see Requesting a Quota Increase in the Service Quotas User Guide.

Your AWS account has the following quotas related to Amazon EBS.

Considerations
  • Your quotas can change over time. Amazon EBS constantly monitors your provisioned storage and IOPS usage within each Region and might automatically increase your quotas, on a per-Region basis, based on your usage. Even though Amazon EBS can automatically increase your quotas based on your usage, you can request a quota increase if needed. For example, if you plan to use more gp3 storage in US East (N. Virginia) than your current quota, you can request a quota increase for that volume type in that Region ahead of your planned usage.

  • The quota for Concurrent snapshot copies per destination Region is not adjustable using Service Quotas. However, you can request an increase for this quota by contacting AWS Support.

  • The IOPS modifications and Storage modifications quotas apply to the aggregated current value (for size or IOPS, depending on the quota) of volumes that can undergo modifications concurrently. You can make concurrent modification requests for volumes that have combined current value (for size or IOPS) up to the quota. For example, if your IOPS modifications for Provisioned IOPS SSD (io1) volumes quota is 50,000, you can make concurrent IOPS modifications requests for any number of io1 volumes as long as their combined current IOPS is equal to or less than 50,000. If you have three io1 volumes provisioned with 20,000 IOPS each, you can request IOPS modifications for two volumes concurrently (20,000 * 2 < 50,000). If you submit a concurrent IOPS modification request for the third volume, you exceed your quota and that request fails (20,000 * 3 > 50,000).

  • Amazon EBS has a non-adjustable limit of 2,500 EBS volumes per instance launch request. This applies to instance launch requests that you make, and to instance launch requests made by AWS services, such as Amazon EMR, on your behalf. If your instance launch request fails as a result of exceeding this limit, we recommend that you adjust the EBS volume configuration in the launch request to ensure the number of volumes is below the limit, or that you work with your technical account manager (TAM) to explore other options for launching your cluster without exceeding the limit.
