VDC compute policies

For the recovered virtual machine (VM), to configure VM-host affinity rules that control the placement of the workload, when creating or modifying a replication, select a VM placement policy for a specific cluster or host or leave the pre-selected one when available. Similarly, by selecting a VM sizing policy, set the compute resources consumption for the recovered workload within an organization VDC to several predefined sizes.

VMware Cloud Director Availability allows the providers and their tenants to select two types of VDC compute policies for the recovered virtual machines:

• VDC VM placement policy
• VDC VM sizing policy

Pre-selected matching VDC VM policies:

Since version 4.7, when VDC compute policies already apply on the source VM, VMware Cloud Director Availability can determine their names. Then the New replication wizard compares each of the placement and the sizing policies by name, and when they match in the destination site, pre-selects the matching ones in the drop-down menus that list the available VDC policies. From the users perspective, there are no further actions needed to use the VDC policies as they are already selected for them.

Prerequisites

Verify that VMware Cloud Director Availability 4.7 or later is successfully installed and configured in both the source and in the destination sites to automatically pre-select the names of the matching policies.

To select from the available VDC compute policies:

• For new replications, the VDC policies show in the New replication wizard. For more information, see Create a protection or Create a migration.
• For existing replications, the VDC policies show in All Actions > Replication settings. For more information, see Configure replication settings.

For information about the compute policies in VMware Cloud Director, see Understanding VM Sizing and VM Placement Policies in the VMware Cloud Director Service Provider Admin Portal Guide.

Placement Policy

VMware Cloud Director Availability 4.3 and later allow selecting a placement compute policy for a specific cluster or host for the recovered virtual machine.

VDC VM placement policy:

Placement policies represent organization VDC compute policies that define the VM-host affinity rules controlling the placement of tenant workloads on a host, group of hosts, or one or more clusters. Selecting a placement policy adds the recovery VM to a VM group in vCenter Server, where the VM groups represent the host group to which they have positive affinities. A positive affinity rule places a VM group on a specific host.

For information about creating placement policies in a provider VDC and about adding them to an organization VDC, select a VMware Cloud Director version in the following VMware Cloud Director documentation.

• See Create a VM Placement Policy within a Provider VDC.

• See Add a VM Placement Policy to an Organization VDC.

Sizing Policy

VMware Cloud Director Availability 4.5 and later allow selecting a sizing compute policy for a specific set of predefined compute resource allocation for the recovered virtual machine.

VDC VM sizing policy:

Sizing policies define the compute resource allocation for virtual machines within the organization VDC. With these policies, VMware Cloud Director system administrators control the following compute resources consumption at the virtual machine level:

• vCPUs number and clock speed.
• Memory amount.
• CPU and memory reservation, limit, and shares.
• Extra configurations.

For information about these attributes, see Attributes of VM Sizing Policies in the VMware Cloud Director Service Provider Admin Portal Guide.
