Hi,
For standalone vSPhere Replication you need to have vSphere 5.1 , with ESXI and vCenter 5.1.
On DR, site you have to mount the datastore on DR sites and then register the VM manually at DR sites. The Power On. You may get the scripts to run it on all the ESXI host, so that it can find all the VM from datastore and then register it. Then you can power On.
