Horizon Workspace lets enterprises achieve failover and redundancy by adding multiple virtual machines of the same type in the Horizon Workspace vApp. For instance, you can add a second gateway-va virtual machine and enable the load balancer to redirect requests to both gateways. If one of the gateway-va virtual machines shuts down for any reason, Horizon Workspace will still be available.

In order to add a new virtual machine of any type, you must log in to the configurator-va virtual machine as root user and run the hznAdminTool addvm --type=VMType --ip=New VM IP address command.

Important

The hznAdminTool addvm --type= command must be executed only after both the command-line and Web interface configuration of Horizon Workspace vApp is completed successfully.

The new virtual machine IP address must follow the same guidelines as the IP addresses for the base virtual machines. It must resolve to a valid hostname using forward and reverse DNS. This IP address must be set up using the same netmask, network gateway, and DNS server name used in the original IP pool to deploy the vApp.

For data-va virtual machines, this command clones the data-va virtual machine from the datava-template virtual machine. For all other virtual machines, this command creates the new virtual machine by cloning a base snapshot of the original virtual machine of the same type. The base snapshot is captured for all virtual machines during the initial deployment. The command fails if the base snapshot does not exist.

The Configurator virtual machine is a singleton. You cannot create multiple Configurator virtual machines.

Your enterprise can create multiple gateways of the same type to distribute traffic and eliminate potential downtime.

Your enterprise can create multiple service-va virtual machines of the same type to distribute traffic and eliminate potential downtime.

Your enterprise can create multiple connector-va virtual machines of the same type to reduce traffic and eliminate potential downtime.

When a large number of users store and read files at the same time, the intense input/output processing can affect performance on the data-va virtual machine. You can add additional data-va virtual machines to balance the load.
