You can manage computes resources by expanding the tree on the Compute Resources panel of the Resources page.
When you expand the tree down to the compute resource level, the following tabs display: General, Tenants, and Datastore Config.
Selected items on the tab are described below.
'Compute resource role' field
The compute resource role can be Active, Reserved, or Standby.
Compute resources can host either virtual desktops or management appliance VMs. You can use the compute resource role to define how a compute resource is to be used. The compute resource role is only relevant for desktop compute resources. While a role can be set on a management compute resource, it has no effect on the use of that compute resource.
From the Compute Resources panel under service grid -> resources, expand the Virtual Center tree down to the compute resource level. Select a compute resource, then select the role from the drop-down box.
Active - An active compute resource is a compute resource that is actively hosting virtual desktops.
Standby - A standby compute resource is a compute resource that can host desktops in the event that another compute resource fails. However, the compute resource recovery option is not available for Desktop Managers that are using vCenter compute resources. If compute resource recovery is needed for vCenter compute resources, it's recommended to use vCenter to migrate desktops from the failed compute resource to a new compute resource.
Reserved - A reserved compute resource is a compute resource that will not be used for provisioning desktops.
The Usage field shows the value(s) selected in the Usage setting (see Edit Compute Resource below).
'Edit Compute Resource' button
Selecting the Edit Compute Resource button allows you to make the following settings.
Over-allocation ratios for the compute resource - VMware recommends the following values:
Memory Over allocation Ratio: 1.0
Virtual to Physical CPU Ratio: 10.0
Sharing of compute resource - If this host manager is to be shared between 2 or more tenants, check the "Share This Compute Resource" box. Note that this option must be selected at discovery time and cannot be changed after the compute resource has been assigned.
Usage - This setting indicates the usage(s) for the compute resource. You can select one or more of the following.
Service - Service Provider, Resource Manager and NSX Controllers
Tenant - Tenants, Desktop Managers, Access Points
Network - Edge Gateway Servers
This setting does not affect desktop deployment selection.
The Tenants tab lists the tenants using this compute resource.
This tab lists the datastores that are configured on this compute resource.
