This screen lists all the available VNFs and their status.

At the top of the screen the currently committed resources are displayed, i.e. how many cores are in use and how much memory is currently in use.

By default the Multi-Tenant LoadMaster will only start running instances which do not exceed the total amount of available hardware resources. Selecting the Allow Overcommitment of Resources check box allows resources to be overcommitted. This can have an impact on performance.

A number of Actions can be performed on each VNF:

  • Start/Stop: Start/stop this VNF.
  • AutoStart/No AutoStart: Specify whether the system should auto-start this VNF upon Multi-Tenant LoadMaster 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 (if it is running), 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 Open vSwitch (OVS) per physical/VLAN interface. This is the Virtual Switch software in the Multi-Tenant LoadMaster which allows multiple VLMs to share a common switch fabric. 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 ETH0… 9.

To modify a VNF, click the Configure button in the VNF Status screen. Various options can be set on the VNF settings screen.

Note: The VNF has to be stopped in order 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. Refer to the VNF Status section for further information on the stop option.

Name: The name of the VNF.

Memory: The amount of memory that the VNF uses.

CPUs: The number of CPUs that the VNF uses.

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: Enter the interface number.

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

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

Add Interface: Add the interface.

Delete Interface: Delete the interface.

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

Reset: Reset all values.

Apply: Apply the changes to the VNFs.

Manage a VNF

To access the screen to manage a VNF, click the VNF Management button on the VNF Status screen. 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, in the format YYYY_MM_DD.HH_mm. 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

Show a list of previous backups for this VNF.

Restore: Restore the backup to the VNF.

Download: Downloads the backup to the local machine.

Delete: Deletes the backup.

Templates

A list of Available Templates which exist on the Multi-Tenant LoadMaster is displayed on the left. Templates can be uploaded to the Multi-Tenant LoadMaster in the Manage Templates screen. For more information on uploading templates to the Multi-Tenant LoadMaster, refer to the Manage Templates section.

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. All Installed Templates will be available for use in the relevant tenant VLM.
