Configuring VMware integration to automatically migrate virtual machines impacted by alarms

Once this integration has been configured, physical location, alarm, and impact data is communicated from ITA to the VMware vCenter server. Based on this data, the VMware environment is then able to move the relevant virtual machines to healthy hosts.

To configure the integration between ITA and VMware vCenter Server:

1. Ensure you have the necessary user rights on the VMware vSphere Client. vMotion functionality is being utilized and must be configured and enabled as well as user rights given.
2. In System Setup > External System Configuration, configure the server communication settings to allow ITA to exchange data with the VMware environment.
   1. Click Add server to type the logon information of the new vCenter Server to connect to: hostname/IP address, port number, and user credentials.
      If you connect to more than 5 vCenter servers, you may experience a performance decrease with the server communication.
   2. For a high-security logon session, select Use SSL and accept the certificate. Ask the vCenter Server administrator for details if you are unsure whether to use SSL.

Once you have set up this server communication, ITA displays virtual machine hosts in the Device Association view. These discovered Virtual Machine hosts need to be associated with modeled servers in the ITA data center model. Virtual Machine host data from the VMware vCenter Server is sent to ITA which, in return, sends physical location, alarm and impact data of virtual machine hosts.

For each host for which you want to enable this feature, you must set the properties to include it in the impact analysis. Otherwise, it will not show as impacted and the virtual machine management system will not be notified of an impact on the host and enable migration. The option is available by right-clicking the virtual machine host, and selecting Properties > Virtual Machine Host and then enabling Enable Power and cooling impact for this host.
