Mirrorview ist doing a blocklevel replication. If you mirror a lun with a vmware datastore on it then you have the komplete vmfs filessystem on the remote side but in case of a failover you have to mount the datastore and import all virtual machines manualy etc. VMware SRM (Site recovery manager )  would take care of all this on the vmware side. Mirrorview is "only" providing a block level mirror of the source lun VMware SRM is running on top of it taking care of all VMware operations needed. If you are familiar with vSphere PowerCli you cold also automate this with scripts but you would have to write, test and mantain them on your own.  [URL] See chapter 4.
