Quotas and limits in Object Storage

Written by
Yandex Cloud
Updated at April 28, 2025

Yandex Object Storage has the following limits:

  • Quotas are organizational constraints that our support team can change upon request.
  • Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, you can increase your quotas in one of the following ways:

  • Make a request to increase your quotas.
  • Contact support, detailing which quotas you want increased and by how much.

To have your request processed, you must have the quota-manager.requestOperator role or higher, e.g.,editor or admin.

You can manage quotas using Cloud Quota Manager.
