Ideally I would like to have them boot from a common storage pool connected via iSCSI. Two of the servers would be main production and one idling so that should one of them have a hardware problem, the 3rd could be fired up to boot from the LUN for that server images that has gone down.
No need to move VM's around and the workload is fairly static.
Just wondering which version of VMWare I would need to do this?
I was thinking of VMware vSphere Essentials and Essentials Plus.
Does that sound right?
