How to start the Virtual Room Connector Load Balancer

Note: We are happy to announce that we have upgraded the Cent OS load balancer to version 7.6 as of April 30th, 2020. In order to implement the latest version of the load balancer, the latest version of the VMDK and OVF files must be used to deploy the latest VMDK.

In order to be able to scale the deployment of the Virtual Room Connector Load Balancer for large scale deployments, it can be used with multiple Virtual Room Connectors. Having deployed the load balancer, once the dial-in address for H.323 and SIP calls are available in Zoom, the load balancer can be used as the dial-in address for Zoom meetings.

A load balancer is included as part of the Virtual Room Connector and can be installed on any VMWare virtualization platform that supports OVF, including but not limited to:

  • There are three VMware products: VMware VSphere, VMware Workstation, and VMware Fusion
  • The Nutanix environment (tested on Nutanix AHV and ESXi (AOS 5.5.5))
  • Supports Hyper-V (best-effort support) on Windows Server 2012/2016.
  • Support for Virtual Box is provided on a best-effort basis.

You may find additional information for the load balancer in the system specifications.

In order for the Virtual Room Connector Load Balancer to function, some prerequisites must be met

  • Accounts for businesses, schools, or enterprises
  • Who wish to subscribe to the Room Connector
  • service that is available on a virtualized server

Deploying the load balancer

  1. Sign into your Zoom account on your web browser and select H.323/SIP Room Connector.
  2. The Virtual Room Connector tab will appear.
  3. Please click on the Virtual Room Load Balancer option under Download & Token.
  4. Please download the OVF and VMDK files.
  5. You can open them in your VM client and deploy them there.
  6. After starting the Virtual Machine, enter the default credentials and log in with them:
    • Username: admin
    • Password: Upon starting the UAC, this password is randomly generated. However, a customized password can be set so that it will not be displayed on startup.

  7. If you want to check the IP address of the server, you should run the command ifconfig. To setup an IP address manually, you have to make sure that the server has one.

  8. Enter your username and password in the default field. Change your password when you first log in.
  9. Now return to the web portal’s Virtual Room Connector tab and login again.
  10. You should be able to copy the token from the Virtual Room Connector tab.
  11. Click Configure in the Virtual Room interface.
  12. Enter the Token into the appropriate field in the virtual room interface.
  13. (Optional) Change the IPV4 Address if desired.
  14. Then click Submit.

Load balancing is enabled once the load balancer has been enabled

  1. You can now return to the Virtual Room Connector tab in the web portal after the reboot has taken place.
  2. On the virtual room connector tab, click Turn on the load balancer.
  3. Enter the address from step 10, and then click Save.
  4. Visit your web console for Virtual Room Connector, and log in.
  5. You will be asked to configure the Virtual Room Connector.
  6. In the Controller 1 IPv4 Address field, you need to enter the load balancer’s IP address.

    Note: If there are more than one load balancer installed in an environment, you must enter a second IP address in the Controller 2 IPv4 Address field.
  7. When you are done, click Submit.

  2. Login using your admin credentials to gain access to the VM.
  3. Select User and then Manage.
