View and manage quotas
To prevent system capacities from being exhausted without notification, you can set up quotas. Quotas are operational limits. For example, the number of gigabytes allowed for each tenant can be controlled so that cloud resources are optimized. Quotas can be enforced at both the tenant (or project) and the tenant-user level.
Typically, you change quotas when a project needs more than ten volumes or 1 TB on a compute node.
Using the Dashboard, you can view default Compute and Block Storage quotas for new tenants, as well as update quotas for existing tenants.
Note
Using the command-line interface, you can manage quotas for the OpenStack Compute service, the OpenStack Block Storage service, and the OpenStack Networking service (see OpenStack Admin User Guide). Additionally, you can update Compute service quotas for tenant users.
The following table describes the Compute and Block Storage service quotas:
Quota Descriptions
Quota Name | Defines the number of | Service |
---|---|---|
Gigabytes | Volume gigabytes allowed for each project. | Block Storage |
Instances | Instances allowed for each project. | Compute |
Injected Files | Injected files allowed for each project. | Compute |
Injected File Content Bytes | Content bytes allowed for each injected file. | Compute |
Keypairs | Number of keypairs. | Compute |
Metadata Items | Metadata items allowed for each instance. | Compute |
RAM (MB) | RAM megabytes allowed for each instance. | Compute |
Security Groups | Security groups allowed for each project. | Compute |
Security Group Rules | Rules allowed for each security group. | Compute |
Snapshots | Volume snapshots allowed for each project. | Block Storage |
VCPUs | Instance cores allowed for each project. | Compute |
Volumes | Volumes allowed for each project. | Block Storage |
