Configure Resource Groups
All server instances must belong to a resource group. The resource group is identified by a set of physical cores that are members of the group and is associated with some number of datastores and networks.
CPU Core Assignment
When creating or editing a resource group, a system administrator controls which cores are assigned to the group and therefore on which physical cores a server in the group can execute on. Additional attributes of a resource group are the CPU scheduler and pinning policy that is to be applied across the selected cores, and the CPU core overcommit policy.
To create a resource group:
- Click the Resource Group tab.
- Click the Create Resource Group button.
- Fill in the configuration form step by step:
What should you see if there is no Resource Group available?
If the system has not been configured previously, then the Resource Grpups menu option should present the following:
Step 1 - Select Storage Optimisation / Enable Fault Tolerance
The Storage Optimisation option is enabled by default.
The 'Enable Fault Tolerance' option allows you to specify the Unit of fault tolerance required (Blade/Chassis/Rack) and the maximum number of Units allowed to be lost whilst still remaining fault tolerant.
Also visible is the option to Automatically Failover in the case of a failed Unit.
Step 2 - Select available datastores that will hold VM data
Select one or more data stores that are accessible to the resource group according to step 1 selections
Step 3 - Select the compute node resources (NexVisors)
Select the members (compute nodes) that you want to make part of the resource group.
Step 4 - Select the cores that will be assigned to the group
Select the cores on each member to assign to the resource group.
Step 5 - Assign the networks to which the instances may have access
Select one or more networks that are accessible to the resource group.
Step 6 - Finalise the configuration
Enter a name and description. Click the Finish button to complete the resource group creation.
What should you see when a Resource Group is available?
If the system has been configured previously, then the Resource Groups menu option should present the following:
Emphasis on the GREEN ICON that indicates that the resource group is storage optimised.
