Seeing that HA is not available in Essentials Kit we currently have, we should first upgrade to Essentials Plus?
We do not have external SAN or any type of shared storage. Does the vStorage virtual appliance (part of Essentials Plus) compensate the lack of physical SAN i.e. can that applliance simulate a SAN and provide HA using the two physical hosts we currently have?
Correct, the vSphere Storage Appliance should be able to help you with this. The vSphere Storage Appliance is a solution that allows you to use "local disks" to your hosts and offer that up as a shared datastore. Do note that when you are using 2 hosts you will lose 50% of your storage straight away due to mirroring of data. And that doesn't include the RAID you have applied to the disk configuration.
