NetApp Data Motion allows uses to move the identity of an entire Storage controller (a vFiler) from one piece of hardware to another.
Sound familiar? It should, it is very similar to VMware’s vMotion in that the storage controller moves intact with its host names, ISCSI sessions, NFS sessions and of course data from one storage array to another. This will allow users to move workload on the storage infrastructure just as they do with vMotion on the virtual server infrastructure. NetApp Data Motion provides an outstanding compliment to VMware vMotion, as it combines the granular VM mobility with dense VM mobility.  This will assist with planned maintenance, hardware upgrades and ultimately storage load balancing just as DRS load balances the servers. This I believe to be the next big step to a fully virtualized datacenter and ultimately cloud computing. Data Motion of course is not magic and not an illusion, we really are moving the storage from one piece of hardware to another with no disruption of service.
