Wrong description of features in the article...
vMotion has nothing to do with disaster recovery; it allows you to move a live, running VM from one ESX server to another. If there's a disaster, there's no running VM to move, and no vMotion to perform.
The essentials plus bundle does get you the HA features, which is an automatic restart of a failed VM, in the event of hardware failure of the hosting ESX server. HA, however, is a high availability feature, not a disaster recovery feature.
To cover a DR scenario, you'll need software to replicate the VMs and their disks to another site.
