  • Requirements

    • Update Resource Limit: Root/Domain Admin should be able to limit the following resources
      • CPUs
      • RAM
      • Primary (shared) storage (Volumes)
      • Secondary storage  (Snapshots, Templates & ISOs)
      • Network bandwidth rate (in bpsmbps)
    • Usage: Limits can be imposed on Accounts, Domains and Projects.
    • List Resource Limit: Any User/RootAdmin/Domain Admin can list Resources
    • Resource Limit Logs: Ensure proper logs are maintained into vmops.log and api.log 

...

  • Configuration

    • global configuration parameters:
      • max.account.cpus - Maximum number of CPU cores that can be used for an account. Default value for this is 40.
      • max.account.ram (in MB) - * Maximum RAM that can be used for an account. Default value for this is *40960.
      • max.account.primary.storage   (in GB)   - Maximum primary storage space that can be used for an account. Default value for this is 20*10.
      • max.account.secondary.storage   (in GB)   - Maximum secondary storage space that can be used for an account. Default value for this is is 20*20.
      • max.account.network.rate (in mbps)   - Maximum network rate that can be used for an account. Default value for this is is 200.
      • max.project.cpus   - Maximum number of CPU cores that can be used for an account. Default value for this is is 40.
      • max.project.ram (in MB) - * Maximum RAM that can be used for an account. Default value for this is  40960* 40960.
      • max.project.primary.storage   (in GB)   - Maximum primary storage space that can be used for an account. Default value for this is is 20*10.
      • max.project.secondary.storage (in GB)   - Maximum secondary storage space that can be used for an account. Default value for this is is 20*20.
      • max.project.network.rate (in mbps)   - Maximum network rate that can be used for an account. Default value for this is is 200.

  • User permission

    • Normal users would have privilege to list resource limits (listResourceLimits).
    • Root-Admin would have privilege to list and update resource limits.
    • Domain-Admin would have privilege to list resources and update resource limits that are assigned to the domain.
