This screen lists all the available VNFs and their status.

At the top of the screen the currently committed resources are displayed, that is, the number of cores in use and the amount of memory in use.

Allow Overcommitment of Resources

Selecting this check box allows resources to be overcommitted. This can have an impact on performance.

Note: By default, Multi-Tenant LoadMaster will only start running instances which do not exceed the total amount of available hardware resources.

A table is displayed which contains information and operations pertaining to each VNF. There are a number of columns in this table:

Id: A unique identifier for each VNF

Name: A name to distinguish the VNF

Status: Shows whether the VNF is idle or running

IP Address: The IPv4 or IPv6 address of the VNF. If the VNF is running, this will be displayed as a clickable hyperlink which will bring you to the VNF.

The last column contains a list of Actions:

  • Start/Stop: Start/stop this VNF.
  • AutoStart/No AutoStart: Specify whether the system should auto-start this VNF upon reboot or not.
  • Configure: Modify the settings for this VNF, such as those relating to the memory, CPUs and IP addresses.
  • VNF Management: Administer this VNF including deploying application templates.
  • Delete: Delete this VNF. A VNF cannot be deleted if it is running. To delete a VNF, first stop the VNF, then click Delete.
  • Update License: When the multi-tenant host license is updated, you can update the VNF license by clicking the Update License button. If the VNF is running, you must restart it to apply the new license.
Note: If you update the VNF license, the VNF bal user password is reset to the Multi-Tenant LoadMaster bal user password.

Configure a VNF

The Multi-Tenant LoadMaster creates one Virtual-Switch per physical/VLAN interface. In addition, 10 host local networks are created. The tenant’s vNICs connect either to one of these switches or to one of the host local networks. Each tenant can have up to 10 vNICs named Virt0-Virt9.

On this screen the VNF settings can be modified.

Note: The VNF has to be stopped to make changes on this screen. If the VNF has not been stopped, the fields on this screen will be greyed out. VNFs can be stopped on the VNF Status screen.

Name: The name of the VNF.

Memory: Select the amount of memory that is allocated to the VNF.

CPUs: Select the number of CPUs that have been allocated to the VNF.

Note: There is a limit to the VNF size of the maximum number of cores of a single CPU on a multi-core platform. For example, on a dual CPU system with six cores per CPU, the maximum size that can be configured for a single VNF is six cores.

The second half of this screen lists the interfaces for this VNF along with related operations.

VNF Interface: The interface number.

MAC Address: The Media Access Control (MAC) address of the VNF.

Physical Interface/Virtual Network: To select either a physical interface or virtual network and select the relevant interface.

Add Interface: Adds the interface.

Delete Interface: Deletes the interface.

Note: The interfaces can only be configured when the VNF is not running.

Reset: Resets all values to the default settings.

Apply: Applies the changes to the VNFs.

Manage a VNF

Administrative functions can be performed to VNFs on this screen.

Backup VNF

Take a backup of the VNF.

Note: The backup name includes a date and timestamp. This has a granularity of one minute. If more than one backup is created in the same minute, the original backup (with the same name) will be overwritten. If there is more than one minute between backup attempts, a separate file will be created.

Available Backups

Shows a list of previous backups for this VNF (if any exist).

Restore: Restore the backup to the VNF.

Download: Downloads the backup to the local machine.

Delete: Deletes the backup.

Templates

A list of available Virtual Service templates is displayed on the left. Templates can be moved to the Installed Templates list on the right by selecting them and clicking the right arrow. To remove templates, use the left arrow. Click Install Templates to apply the changes to the VNF.
