Abstract:
A system for operating a virtual machine using a first site and a second site of an active/active system is provided. A host cluster and a director cluster may be identified at each of the first site and the second site. A first link may be provided between the host clusters of the first and second sites. A second link may be provided between the director clusters of the first site and second sites. While the virtual machine is operating on the first site, storage data may be transferred from the first site to the second site. An image of the virtual machine may be transferred from the first site to the second site. At least one of the following may be performed: (i) the storage data is transferred using the first link or (ii) the image of the virtual machine is transferred using the second link.
