Abstract:
A system for providing mobility of a virtual machine between a first site and a second site of an active/active system is disclosed. For a virtual machine operating on the first site, it may be determined that the second site is a destination site between the first site and the second site. While the virtual machine is operating on the first site, storage data may be transferred from the first site to the second site. Operation of the virtual machine may be suspended on the first site. Operation of the virtual machine may be resumed on the second site. In the event of link failure between the first site and the second site, operation of the virtual machine may be maintained on the second site.
