Managing Provider Virtual Data Centers in Your VMware Cloud Director

Activate or Deactivate a Provider Virtual Data Center in Your VMware Cloud Director

In VMware Cloud Director, to deactivate all existing organization virtual data centers (VDCs) that use the resources of a provider VDC, you can deactivate this provider VDC. You cannot create organization VDCs that use the resources of a deactivated provider VDC.

Running vApps and powered on virtual machines continue to run in the existing organization VDCs backed by this provider VDC, but you cannot create or start additional vApps or virtual machines.

Procedure

From the primary left navigation panel, select Resources, and from the page top navigation bar, select Cloud Resources.
From the secondary left panel, select Provider VDCs.
Click the radio button next to the name of the target provider VDC, and click Enable or Disable.
To confirm, click OK.

Edit the General Settings of a Provider Virtual Data Center in Your VMware Cloud Director

In VMware Cloud Director, you can change the name and the description of a provider virtual data center (VDC). If the backing resource pool supports a higher virtual hardware version, you can upgrade the highest virtual hardware supported by a provider VDC.

Procedure

From the primary left navigation panel, select Resources, and from the page top navigation bar, select Cloud Resources.
From the secondary left panel, select Provider VDCs, and click the name of the provider VDC that you want to modify.
On the Configure > General tab, in the upper right corner, click Edit.
(Optional) Modify the name and the description of the provider VDC.
(Optional) Enter a compute provider scope for the provider VDC.
The compute provider scope represents compute fault domains, or availability zones which are visible to tenants and where workloads reside. By default, the compute provider scope of a provider VDC is inherited from the backing vCenter instance. You can differentiate the compute provider scope for the different provider VDCs that are backed by a single vCenter instance. For example, you can set the vCenter with a compute provider scope Germany and you can set the provider VDC with a scope Munich.
(Optional) From the drop-down menu, select the highest hardware version supported by this provider VDC, and click Save.
The highest version that you can select depends on the ESXi hosts in the resource pool that backs the provider VDC.
Note: You can only upgrade the hardware version supported by a provider VDC. You cannot downgrade the hardware version. VMware Cloud Director supports the highest hardware version that the backing vSphere infrastructure supports. You can set the hardware version without manually configuring the default hardware version in the vCenter instance.
Click Save.

Merge Provider Virtual Data Centers in Your VMware Cloud Director

To combine the resources of two VMware Cloud Director provider VDCs, you can merge these provider VDCs into a single provider VDC.

You can merge provider VDCs that are backed by NSX.

VMware Cloud Director supports merging provider VDCs that are not backed by networking resources, and merging a provider VDC that is not backed by networking resources with an NSX-backed provider VDC.

Prerequisites

Verify that both provider VDCs have the same enabled state.
If you want to merge provider VDCs that are backed by NSX, verify that both provider VDCs are backed by the same NSX Manager instance and by the same Geneve network pool.
Verify that both provider VDCs are backed by the same vCenter instance and by the same data center.
Verify that the provider VDC that you want to expand supports the highest hardware version used in the provider VDC that is to be merged. If the merging provider VDC contains a VM with a higher hardware version than the highest one supported by the expanding provider VDC, the merge fails.
Verify that both provider VDCs contain only elastic organization VDCs.
If you want to merge provider VDCs with network pools that are backed by VXLAN, verify that the VXLAN pools have the same NSX working state. See "Verify the NSX Working State" in the NSX Upgrade Guide.

View the Datastores and Datastore Clusters on a Provider Virtual Data Center in Your VMware Cloud Director

In VMware Cloud Director, you can view details about the datastores and datastore clusters that provide the storage capacity to a provider virtual data center (VDC).

To see the list of storage containers for all provider VDCs, navigate to Storage Containers under the Infrastructure Resources tab.

Procedure

From the primary left navigation panel, select Resources, and from the page top navigation bar, select Cloud Resources.
From the secondary left panel, select Provider VDCs, and click the name of the target provider virtual data center.

Select the Storage Containers tab.

A list of all datastores and datastore clusters on the provider virtual data center appears. The list contains the following information for each container type.


Title	Description
Name	The name of the datastore
State	Activated or deactivated
Type	The type of file system that the datastore uses, such as Virtual Machine File System (VMFS), Network File System (NFS), vSphere Virtual Volumes, or vSAN datastores.
Used	The datastore space occupied by virtual machine files, including log files, snapshots, and virtual disks. When a virtual machine is powered on, the used hard disk space also includes log files.
Provisioned	The datastore space guaranteed to virtual machines. If any virtual machines are using thin provisioning, some of the provisioned space might not be in use, and other virtual machines can occupy the unused space. This value might be larger than the actual datastore capacity if thin provisioning is used.
Requested	Provisioned storage in use only by VMware Cloud Director objects on the datastore, including: Virtual machines provisioned in VMware Cloud Director Catalog items (templates and media) NSX Edges Used and unused memory swap requirements for virtual machines This value does not include storage requested by shadow VMs or intermediate disks in a linked clone tree.
Threshold Yellow	You receive an email from VMware Cloud Director when the datastore or datastore cluster reaches a specific threshold of available capacity. By default, VMware Cloud Director sets the yellow threshold to 25% of the stand-alone datastore or datastore cluster's total capacity.
Threshold Red	You receive an email from VMware Cloud Director when the datastore or datastore cluster reaches a specific threshold of available capacity. By default, VMware Cloud Director sets the red threshold to 15% of the stand-alone datastore or datastore cluster's total capacity. When a datastore reaches its red threshold, the virtual machine placement engine stops placing new virtual machines on the datastore except for already-placed imported VMs.
vCenter Server Name	The vCenter instance associated with the datastore.

(Optional) To see a list of the datastores in a datastore cluster, select the Datastore Cluster container type and select the Datastores tab.

What to do next

To edit the storage container thresholds, see Configure Low Disk Space Thresholds for a Provider Virtual Data Center Storage Container in Your VMware Cloud Director

Configure Low Disk Space Thresholds for a Provider Virtual Data Center Storage Container in Your VMware Cloud Director

You can configure low disk space thresholds on a storage container to receive an email from VMware Cloud Director when the datastore reaches a specific threshold of available capacity. These warnings alert you to a low disk situation before it becomes a problem.

There are two datastore thresholds in VMware Cloud Director.

Red threshold - the amount of free space on a datastore, below which, VMware Cloud Director filters out the datastore during the placement of any entity such as a VM, a template, or a disk.
When a datastore reaches its red threshold, the workload placement engine stops placing new VMs on the datastore except while importing VMs from vCenter. In the case of VM import, if the vCenter VM is already present on the red threshold datastore, the placement engine prefers the existing datastore.
The workload placement engine uses the red threshold for all workflows. When making a request for any new placement, the placement engine first filters out any datastores or storage pods which have breached the red threshold. When making a placement request for an existing entity, if the disks are residing on the datastores that are breaching the red threshold, VMware Cloud Director relocates the disks to other available datastores. Then, the engine selects a datastore out of the remaining datastores or storage pods, either through the selector logic of VMware Cloud Director or from the vSphere Storage DRS recommendations.
Yellow threshold - the amount of free space on the datastore, below which VMware Cloud Director filters out the datastore during the placement of shadow VMs from which VMware Cloud Director creates fast-provisioned VMs. For more information on shadow VMs, see Fast Provisioning of Virtual Machines.
The yellow threshold does not apply to the linked clones that VMware Cloud Director uses for fast provisioning of VMs. When the placement engine selects a datastore for a linked clone, if the selected datastore is missing a shadow VM, VMware Cloud Director creates a shadow VM on the datastore. The threshold does not apply to the shadow VM in this case.
The yellow threshold applies only to the periodic background job creating shadow VMs. If activated, the job runs every 24 hours and uses eager VM creation on each datastore for a given hub and storage policy pair. To activate the job for eager provisioning of shadow VMs, you must set the following property to true.
```
valc.catalog.fastProvisioning=true
```
Note: The periodic background job creates shadow VMs on all datastores for all templates. The job increases the storage consumption even when you are not using the datastores or shadow VMs.

When implementing the threshold logic, VMware Cloud Director does not evaluate the requirements of the current placement subject. For the workload placement engine to place a subject on a datastore, the available space in bytes must be more than the threshold in bytes. For example, for a datastore with available capacity of 5 GB with a red threshold set at 4 GB, the placement engine can place a VM with a requirement for 2 GB. If the VM creation breaches the threshold, the placement engine filters out the datastore for further placements.

When you set thresholds on a stand-alone datastore, they apply only to that datastore. If you set thresholds on a datastore cluster, they apply to all datastores in the cluster. By default, VMware Cloud Director sets the red threshold to 15% and the yellow threshold to 25% of the stand-alone datastore or the datastore cluster's total capacity.

Because the default thresholds on a datastore cluster are based on the total cluster capacity, the thresholds might exceed the capacity of individual datastores within the cluster. When setting thresholds on a datastore cluster, consider the capacity of each datastore in the cluster and set thresholds manually rather than accepting the default threshold configurations.

Procedure

From the primary left navigation panel, select Resources, and from the page top navigation bar, select Cloud Resources.
