You can manage compute resources for a resource manager on the Compute Resources tab.

The Compute Resources tab shows the status and type of each compute resource associated with this resource manager. You can also remove the association of a compute resource from a resource manager by clicking the remove button.

Reassigning a Compute Resource

A Reassign button appears on the Compute Resources tab. You can use this button to add a compute resource.
Note: You cannot remove compute resources after they have been assigned.

To reassign compute resources assigned to your tenant:

  1. In the Assigned Compute Resources section, click Reassign next to the Virtual Center.
  2. Select a compute resource in the Desktop Compute Resources dialog box.

    A capacity dialog box appears for the compute resource you selected.

  3. Edit information as described in the following table.
    Field Description
    Failover Hosts Number of hosts 100% reserved for disaster recovery. This value must be lower than the value for Hosts Detected. If multiple hosts are detected, the default value is 1. If a single host is detected, the default value is 0.
    Host Headroom Percent For the remaining hosts (those not designated as Failover Hosts), enter the percentage of capacity to reserve for disaster recovery. The default value is 20.
    • The value for Memory Available is equal to Memory Installed reduced by the percentage you enter for Host Headroom Percent.
    • The value for CPUs Available is equal to CPUs Installed reduced by the percentage you enter for Host Headroom Percent.
    Memory Over allocation Ratio This ratio determines the amount of virtual machine memory that the compute resource can allocate. For example, if the ratio is 4.0 and the memory capacity of the compute resource is 64 GB, then it supports up to 256 GB of virtual machine memory. The default value is 1.5.
    Virtual to Physical CPU Ratio This ratio determines the number of virtual machine CPUs that the compute resource can allocate. For example, if the ratio is 8.0 and the number of physical CPU cores on the compute resource is 8, then it supports up to 64 virtual machine CPU cores. The default value is 10.
    Usage Select one or more of the three options (Service, Tenant, Network).
    • Select Service to install Service Provider and Resource Manager appliances on the cluster.
    • Select Tenant to install Tenant and additional Desktop Manager appliances on the cluster.
    • Select Network to install Network appliances like Unified Access Gateway and NSX Edge Gateway on the cluster.
    If you only have one cluster, select all three options.
  4. Click Save.

    If this compute resource is shared, the Partitioned Compute Resource dialog box displays. In this dialog box, set partition sizes for Memory and CPU, and click Save.

    Note: You can later view and edit these settings on the Quotas tab when editing a tenant.
