We are currently looking to implement a Geo Spatial Infrastructure (see below) that will include a number of servers and we are planning to run each server on a different virtual machine. At the very early stage we will be using two physical servers (one as a replica of the other)
I am a newbie to the virtualization world but from the Basic research that I have done and from the basic consultancies that I have done with local companies, I have come across the terms VMware vSphere,VMware vCenter and VMware SRM (vCenter Site Recovery Manager)? Can anyone explain the differences between them? Why would I need two vCenters and six Vspheres? I understand there is a virtualization OS, a virtualization management server and virtualization client but which is which and what is necessary and what is not.
Thanks!
