vCenter Basic Resource
Information about the vCenter Basic Resource
ZStack Cloud can manage vCenter basic resources, namely vCenter virtual resources, in a unified manner, currently including the addition of a vCenter, vCenter data synchronization, and the deletion of a vCenter.
After you add a vCenter to the Cloud for the first time, ZStack Cloud will automatically synchronize the clusters, hosts, VM instances, templates, storages, networks, and other resources in the vCenter. You can also synchronize the resources of the vCenter to your current Cloud while you are using it by clicking Sync Data. Then, you can view all these resources on the UI.
- You can add and manage multiple vCenters.
- You can filter the vCenter resources before you import them into ZStack Cloud.
- dvSwitch scenario:
Only resources of the hosts that are added to a dvSwitch can be imported to ZStack Cloud. If you do not add a host to a dvSwitch, the associated resources cannot be imported to ZStack Cloud.
- vSwitch scenario:The resources imported to ZStack Cloud must be the resources of the hosts in the same cluster and must be added with at least one same vSwitch name. In addition, they must have at least one same port group attribute (including the same network labels and the same VLAN ID) at the same time.
Note: ZStack Cloud can only manage VM networks rather than VMkernels or management networks.
- dvSwitch scenario:
Add a vCenter
The following table displays the information required to add a vCenter.
| Field | Description | Example |
|---|---|---|
| Access Domain Name | The address used to access the vCenter: a domain name or an IP address. |
|
| Administrator | The user name for the vCenter administrator. This filed should include an intact domain. | administrator@vsphere.local |
| Access Password | The password for the vCenter administrator. | Testing123 |
On the main menu of ZStack Cloud, choose . On the Basic Resource page, click Add vCenter. Then, the Add vCenter page is displayed.
On the displayed page, set the following parameters:
- Name: Enter a name for the vCenter.
- Description: Optional. Enter a description for the vCenter.
- Domain: Enter a domain for the vCenter.
The Domain here is a domain name or an IP address used to access the vCenter, for example, 172.20.1.166.
- Port: Enter an available port number of the vCenter.
- User: Enter a user name for the vCenter. The name should include an intact domain.
- Password: Enter the password corresponding to the vCenter user name. The password should match the practical environment and is case-sensitive.
- HTTPS/HTTP: Select a transfer protocol for vCenter synchronization. You can choose either HTTP or HTTPS. Default option: HTTPS.
vCenter Details Page
After you add a vCenter successfully, ZStack Cloud will import the clusters, hosts, VM instances, templates, storages, networks, and other resources in the vCenter.
You can view the Overview, Cluster, Primary Storage, Backup Storage, Host, Resource Pool and Audit tab pages on the details page:
- Overview: This tab page displays the information of the added vCenter, including the basic information and the number of the associated resources.
- Cluster: This tab page displays the list of the vCenter clusters managed by the Cloud. The displayed information includes the name, the hypervisor type, the number of the hosts, and the state of the clusters.
- Both the Primary Storage and the Backup Storage tab pages support a datastore list to display the relevant information.
- The Host tab page allows you to view the states of the hosts in the maintenance mode.Note:
- If a host on the remote vCenter is in the maintenance mode, you can view its state locally via data synchronization.
- Resource Pool: This tab page displays a list of the resource pools of the managed vCenters, the resource pools and the resources in them (including other resource pools and VM instances). The other information displayed includes the name, type, parent item, VM instance quota, and CPU/memory capacity limit of the vCenter.The details page of a single resource pool displays the reservation of the CPU/memory capacity (you cannot allocate the reserved resource capacity), the limit (the upper limit of the allocated resource capacity), quota (the proportional weight of the resource sharing) and other information of the pool.
- Reservation: Specify the lower limit of the CPU/memory allocation for the resource pool. The value is 0 by default.
- Limit: Specify the upper limit of the CPU/memory allocation for the resource pool. The value is Unlimited by default.
- Quota: Specify quota value attained by the resource pool relative to the total resource of its parent resource pool. Sibling resource pools share the resources according to their relative quota value bounded by their Reservations and Limits.
Note: - The vCenter VM instances created on ZStack Cloud do not display the resource pool attributes. Therefore, you cannot find their corresponding information on the Resource Pool tab page.
- After upgrading the ZStack Cloud of the historical versions (earlier than ZStack Cloud3.3.0) to the latest version, you need to click Sync Data to view the information of the vCenter resource pools.
- For more details, refer to VMware Official Documentation.
- Audit: This tab page displays the operation log of the vCenter.
Manage a vCenter
On the main menu of ZStack Cloud, click . Then, the Basic Resource page is displayed.
The following table lists the actions that you can perform on a vCenter basic resource.
| Action | Description |
|---|---|
| Add vCenter | Add a vCenter to the current cloud platform. After you add a vCenter, ZStack Cloud automatically synchronizes its clusters, hosts, VM instances, storage, networks, and other resources to local. You can view all these resources on corresponding pages. |
| Edit vCenter | Edit the name and the description of a vCenter. |
| Sync Data | Synchronize the vCenter resources to local.Note:
|
| Update Password | Modify the password of the vCenter. |
| Delete vCenter | Delete a vCenter. Deleting a vCenter also deletes the local records of the associated resources. The actual resources on the remote vCenter are not affected. |
