Optimizing Storage with Quick Storage Migration
Quick Storage Migration helps you optimize your virtual machine storage by rapidly moving virtual
machine assets to different storage locations. Quick Storage Migration helps you take advantage of
Windows Server 2008’s new Cluster Shared Volumes to consolidate multiple virtual machines on a
single LUN. The initial release of Hyper-V required that each VM be located on its own LUN. However,
Migrating to Hyper-V R2 will immediately make all virtual machines previously configured for Quick
Storage Migration able to make use of Live Migration. However, to make storage management easier
you can use Quick Storage Migration to consolidate your existing virtual machines on fewer LUNs. In
addition, Quick Storage Migration can also enable you to make existing local virtual machines that are
not highly available capable of using live migration. Using Quick Storage Migration to move a locally
stored virtual machine to a CSV makes the virtual machine highly available and enables it to utilize live
migration.
