Basic Resource

ZStack can manage vCenter basic resources, namely vCenter virtual resources, in a unified manner, including adding a vCenter, synchronizing data for a vCenter, and deleting a vCenter.

After you add a vCenter for the first time, ZStack will automatically synchronize the clusters, hosts, VM instances, templates, storages, networks, and other resources in the vCenter. To use a managed vCenter, click Sync Data to synchronize vCenter resources to your current Cloud. Then, you can view the associated resources in the UI.

You can add and manage multiple vCenters.
You can filter resources before you import vCenter resources to ZStack.
- dvSwitch scenario:
  Only resources of the hosts added to a dvSwitch can be imported to ZStack. If you do not add a host to a dvSwitch, the associated resources cannot be imported to ZStack.
- vSwitch scenario:
  Only resources of the hosts in the same cluster, added to at least one same vSwitch, and have at least one same port group attribute (including the same network labels and the same VLAN ID) can be imported to ZStack.
  Note: ZStack can only take over VM networks rather than VMkernels or management networks.

Next, we will introduce how to add a vCenter in ZStack.

Prepare the following information in advance.

Field	Description	Example
Access domain name	vCenter access address: domain name or IP address	vc.test.com 172.20.1.166
Administrator	vCenter administrator name, including the intact domain	administrator@vsphere.local
Access password	vCenter administrator password	Testing123

Add a vCenter.
In the navigation pane of the ZStack Private Cloud UI, choose vCenter > vCenter. On the vCenter page, click Add vCenter. On the displayed Add vCenter page, set the following parameters:
- Name: Enter a name for the vCenter.
- Description: Optional. Enter a description for the vCenter.
- Domain Name: Enter a domain name for the vCenter.
- Port Number: Enter a port No. of the vCenter.
- User Name: Enter a user name for the vCenter.
- Password: Enter the password that corresponds to the vCenter user name according to your actual practice. Note that the password is case sensitive.
- HTTPS/HTTP: Select a transfer protocol when you synchronize the vCenter. The supported transfer protocols include HTTPS and HTTP. Default option: HTTPS.
As shown in Add vCenter. Click OK. Then, the vCenter is added.
Figure 1. Add vCenter
After you add the vCenter successfully, ZStack will import the existing clusters, hosts, VM instances, templates, storages, networks, and other resources in the vCenter.
On the vCenter details page, you can view the basic attributes, clusters, primary storages, backup storages, hosts, resource pools, and audit information.
- Specifically, the Basic Attributes tab page displays the overview, resource count, and other information about the vCenter, as shown in Basic Attributes.
  Figure 2. Basic Attributes
- The Cluster tab page displays a list of the vCenter clusters managed by the Cloud, and displays the cluster name, hypervisor type, host count, state, and other information.
- Both the Primary Storage tab page and Backup Storage tab page can display a datastore list, as shown in vCenter Primary Storage and vCenter Backup Storage.
  Figure 3. vCenter Primary Storage
  
  Figure 4. vCenter Backup Storage
- The Host tab page displays the state of the maintenance mode, as shown in vCenter Host.
  Figure 5. vCenter Host
  Note:
  
  If hosts on a remote vCenter enter the maintenance mode, you can view the resource state locally via data synchronization.
- The Resource Pool tab page displays a list of the vCenter resource pools managed by the Cloud. The resource pools and resources (including another resource pools and VM instances) in these pools are displayed in cascade. In addition, the resource pool tab page displays the resource pool name, type, parent item, VM quota, CPU capacity limit, and memory capacity limit, as shown in Resource Pool.
  Figure 6. Resource Pool
  Note:
  
  vCenter VM instances that are created in ZStack do not display resource pool attributes, and will not be displayed on the preceding Resource Pool tab page.
  
  After a historical version (earlier than ZStack 3.3.0) is upgraded to the latest version, click Sync Data before you can view the vCenter resource pool information.
  You can click on the resource pool name or VM name to enter the corresponding details page. The details page of a single resource pool displays information such as the CPU reservation, memory reservation (reserved resource capacities cannot be allocated), limits (the upper limit of allocated resource capacity), and quotas (weight of shared resources), as shown in Single Resource Pool Details Page.
  
  Reservation: Specify a proper CPU quota or memory quota for the resource pool. Default value: 0.
  
  Limit: Specify the upper limit for the CPU quota or memory quota in the resource pool. Default value: unlimited.
  
  Quota: Specify the share (quota) value of the resource pool with respect to the total resources of a parent object (a host, or another resource pool). Sibling resource pools share resources according to their relative share value bounded by the reservation and limit.
  For more information, see VMware Official Documentation.
  As shown in Figure 7.
  Figure 7. Single Resource Pool Details Page
- The Audit tab page displays vCenter operation logs.
On the vCenter details page, click Actions to synchronize data or delete a vCenter.

You can perform the following operations on a vCenter:

Add vCenter: Add a vCenter. After you add a vCenter, ZStack will automatically synchronize the clusters, hosts, VM instances, templates, storages, networks, and other resources of the vCenter. You can view the associated resources in the UI.
Synchronize data: After you synchronize the data for the vCenter, vCenter resources will be synchronized locally in real time.
Note:
- vCenter Server Appliance (vCSA) that you deployed in the remote vCenter will not be synchronized locally to avoid error operations.
- ZStack allows you to automatically synchronize vCenter data. The method is as follows:
  In the navigation pane of the ZStack UI, choose Settings > Global Settings > Advanced. On the Advanced tab page, set vCenter Data Auto Sync Interval, as shown in vCenter Data Auto Sync Interval.
  Figure 8. vCenter Data Auto Sync Interval
Delete: Delete a vCenter. After you delete a vCenter, the local records of associated vCenter resources will be deleted as well. However, the actual resources in the remote vCenter will not be affected.
View cluster: View vCenter cluster information.
View primary storage: View vCenter primary storage information and datastore lists.
View backup storage: View vCenter backup storage information and datastore lists.
View host: View vCenter host information.
View resource pool: View vCenter resource pools, VM lists, and detailed information.
