Quota Management

With the Quota Management feature, you have complete control over the USAGE of your OpenStack Cloud Resources. The principle is simple! Depending on your order and contract, your client account receives a defined maximum number of OpenStack resources (e.g., number of projects, vCPUs, RAM, number of VMs, number and size of storage volumes, etc.). You can then distribute these resources to your OpenStack projects, giving you full control over how much each of your projects uses. If you need a higher limit for certain resource types, such as vCPUs, you can request this directly in the Cloud Services Portal.

Example Quota Management vCPU

The following graphic illustrates the principle of Quota Management using the resource type vCPU as an example.

• Enterprise Partner 1: Has allocated 110 of 5000 vCPUs to Client A (100 vCPUs) & Client B (10 vCPUs).
• Client A: (Production Customer)
  • Has assigned 10 of 100 vCPUs to Project 1 (Develop).
  • Has assigned 80 of 100 vCPUs to Project 2 (Production).
  • Both projects are already using all of their allocated resources.
• Client B: (Trial Customer)
  • Has assigned all 10 of 10 vCPUs to Project 1 (Trial).
  • Project Trial is already using 8 of the 10 vCPUs.

• In this case, this resource type will not be adjusted, but all others will.
• Solution: Adjust your quota profile or request a higher quota for this resource type.

Request more quota

A user can request a higher quota for one or more resource types for their client account from their Enterprise Partner.
