5.2. Viewing Physical Servers Information¶
Hardware Nodes is a common term for physical servers running Virtuozzo. Virtuozzo software can be installed on bare metal servers only.
The Virtuozzo Automator functionality enables you to register, group under logical units, and manage a number of such servers.
If you deal with a large number of registered physical servers (and virtual environments), it can be convenient to organize them into multiple logical units divided by architecture, virtual environment type or other principles. For details on how to do this, consult Organizing Logical Structure.
You can also set up a convenient and automated structure of IP pools. The IP addresses within these pools can be automatically assigned to the certain groups of virtual environments, thus eliminating possible IP conflicts between virtual environments and physical servers. Doing this will also let you save time on manual IP assignment. For details, see Managing IP Pools.
To distribute workload, you can migrate virtual environments between physical servers registered in the Virtuozzo Automator infrastructure.
On the Hardware Nodes screen, you can review the list of physical servers currently registered in Virtuozzo Automator and see the physical server details shown as the following table:
|Status||The status of the physical server.|
|Hostname||The hostname of the physical server.|
|Description||The description of the physical server.|
|Default IP Address||The IP address of the physical server used to connect to Master Server (the physical server with the VA Management Server component of Virtuozzo Automator installed).|
|Operating System||The name and version of the operating system installed on the physical server.|
|Arch||The microprocessor architecture of the physical server.|
|CPU||The percentage of the current CPU load on the physical server. Updated every 10 seconds.|
|Disk||The percentage of the current disk space usage of the physical server. Updated every 10 seconds.|
|Memory||The percentage of the current memory consumption of the physical server. Updated every 10 seconds.|
|Alert||The level of the physical server resources usage signaled by a corresponding alert.|
|Alerted VEs||The number of virtual environments which reside on the physical server and whose level of the resources usage is signaled by a corresponding alert.|
|Running VEs||The current number of running virtual environments residing on the physical server.|
|Stopped VEs||The current number of stopped virtual environments residing on the physical server.|
|Total VEs||The total number of virtual environments residing on the physical server.|
If this screen is loaded in the Logical View mode, the physical servers displayed in this table are those which have been added to the Logical View, otherwise the physical servers list is empty. To add a physical server to the Logical View, click Add To Folder on the toolbar, select Hardware Nodes from the drop-down menu, and click Add, choose the physical server(s) in the displayed window, and click Use Selected, then Save.
To manage any of the physical servers registered in Virtuozzo Automator, click its hostname. To display a certain physical server from a long list, click the Show Search link below the table, enter the name of the physical server and click Search; to restore the list of the physical servers, click Reset Results.
Using the buttons above the table, you can manage physical servers as follows:
- to stop managing a physical server via Virtuozzo Automator, tick its check box and click Unregister;
- to add a new physical server to the list of the servers managed via Virtuozzo Automator, click New Hardware Node;
- to move one or more physical servers to a folder, select them in the table and click Move.
