1- As you can see in the diagram I wish to replicate the servers with eachother in such a way that if one fails, the other takes over etc. How can this be done?
2- I wish to have virtualisation running on both servers. What do I need to have it done? vmware on both servers?
3- I was planning to install the OS and virtualisation solution on servers only and store the virtual servers on the SAN. Does it make sense?
4- Since I will need to setup a DMZ, what device do you suggest that I purchase which would allow me to connect via vpn with it (to the internal network) and at the same time have the option to configure a DMZ?
