Domains

Overview

A Domain is a logical separation of Customer Accounts, Users, and Resources into a single unit. Multiples of these units can exist within a OpenCloud Zone. Domains usually include multiple Accounts related to each other and a set of Administrator Accounts that have authority over the main Domain and any Sub-Domains created.

OpenCloud allows the configuration of Limits on a Domain basis. With a Domain limit in place, all Users still have their Domain limits. Domain limits aggregate the usage of all Accounts in the Domain as well as all the Accounts in all the she Domains of that Domain. Limits set at the root Domain level apply to the sum of resource usage by the Accounts in all the Domains and sub-Domains below that root Domain.

if a Domain is using 20 CPUs and one of its Sub-Domains is using 10 CPUs, then each of the Domains together can only use 10 more if the set limit is 40 CPUs.

Primary or Secondary Storage Space on this document references the stated size of the Volume and not the actual physical size or the actual consumed if it is thin provisioned. This means that Primary Storage limits represent the entire size of the Volume and not just the used size.

Add a Sub-Domain

  1. To add a new Sub-Domain to an existing Domain, first log in to OpenCloud and click on Domains.
  2. Select the existing Top Domain. Note that the highlighted Domain is the one that the new Domain will be placed under, so select the correct Domain first.

  3. To view the current Resource Limits of a Domain, log in to OpenCloud and select Domains, expand the ROOT Domain dropdown, select the Domain in question, and then click on Limits on the right hand side of the screen.
  4. The progress bars will be filled in for used resources and a percentage of used resources will be displayed on the right side of the progress bar.

Maximum Networks The number of Networks, Shared or otherwise, that the Domain can own.
Maximum VPCs The number of VPCs, or Virtual Private Connections, that an Domain can own.
Maximum CPU Cores The maximum amount of CPU Cores that the Domain can use for Instances.
Maximum Memory in MB The maximum amount of RAM that that an Domain can use for Instances.
Maximum Primary Storage The maximum amount of Primary Storage that the Domain can assign to Instances. (Instance Volumes and Instance snapshots)
Maximum Secondary Storage The maximum amount of Secondary Storage that the Domain can assign to Instances. (Templates, ISO, Volume Images, and Volume Snapshots)

Updating Resource Limits for Domains

  1. Customer Domain Admin accounts can only change the Limits of Sub-Domains that they directly control.
  2. To change resource counts for Domains, log in to OpenCloud as an Administrator or using account that can increase resources for Domains.
  3. On the main page, click on Domains.
  4. Make sure the Domain that should have resources increased is highlighted. The command to increase resources will target the highlighted Domain. Make sure to double check that the right Domain is highlighted.
  5. Click over into the Configure Limits section of the screen. This is where the current limits of the Domain will be shown in editable boxes.
  6. Make the necessary Domain Resource Limit changes here and then click Submit at the bottom of the screen.
  7. This is the first step to increasing Resource Limits.
  8. The second step is to click on the button in the upper right that says Update Resource Count.
  9. A dialog box will come up asking for confirmation that the Domain highlighted is the one that should have its Resources increased.
  10. Click OK and then the Resource Limits will be changed. Click off the Domain that Resources were changed for and click back on it to confirm that the Resource Limits have been changed.
  11. Confirm with the customer that they can see and use the updated resources.
