Active/active storage and virtual machine mobility over asynchronous distances

摘要

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.

主权项

1. A method for providing mobility of a virtual machine between a first site and a second site, comprising:
determining 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, transferring storage data from the first site to the second site; suspending operation of the virtual machine on the first site; transferring the virtual machine from the first site to the second site, wherein the virtual machine is transferred separately from the transferring of the storage data; and resuming operation of the virtual machine on the second site.
