HA isn't really an option without a SAN.

You could investigaate vSphere replication; VMware vSphere Replication .

Hope this helps

It's not possible with some kind of shared storage. The standby host needs to read the vm data to power the VM back on. VSAN is an option too.

You could consider 3 x a single CPU server. Which in many cases is cheaper than 2 x Dual CPU server. Another option would be selecting a different storage appliance. vSAN requires 2 + a witness VM somewhere. Or 3 hosts. There are some appliances which only need 2, although I would ask myself what happens if there's a network partition or a host is isolated. How does the appliance know which half owns what?
