The api documentation is now published on docs.openstack.org instead of developer.openstack.org. Update all links that are changed to the new location. Note that Neutron publishes to api-ref/network, not networking anymore. Note that redirects will be set up as well but let's point now to the new location. For details, see: http://lists.openstack.org/pipermail/openstack-discuss/2019-July/007828.html Change-Id: Id2cf3aa252df6db46575b5988e4937ecfc6792bb

Limits
Accounts may be pre-configured with a set of thresholds (or limits) to manage capacity and prevent abuse of the system. The system recognizes absolute limits. Absolute limits are fixed. Limits are configured by operators and may differ from one deployment of the OpenStack Compute service to another. Please contact your provider to determine the limits that apply to your account. Your provider may be able to adjust your account's limits if they are too low. Also see the API Reference for Limits.
Absolute limits
Absolute limits are specified as name/value pairs. The name of the absolute limit uniquely identifies the limit within a deployment. Please consult your provider for an exhaustive list of absolute limits names. An absolute limit value is always specified as an integer. The name of the absolute limit determines the unit type of the integer value. For example, the name maxServerMeta implies that the value is in terms of server metadata items.
Table: Sample absolute limits
| Name | Value | Description |
| maxTotalRAMSize | 51200 | Maximum total amount of RAM (MB) |
| maxServerMeta | 5 | Maximum number of metadata items associated with a server. |
| maxImageMeta | 5 | Maximum number of metadata items associated with an image. |
| maxPersonality | 5 | The maximum number of file path/content pairs that can be supplied on server build. |
| maxPersonalitySize | 10240 | The maximum size, in bytes, for each personality file. |
Determine limits programmatically
Applications can programmatically determine current account limits. For information, see Limits.
