I'm looking at virtualising about 5 or 6 servers on a VMware setup next year. My main question here is what sort of setup should i be looking for? I have heard a few of you talk about ESXi and a SAN, but I have no experience in either so i don't know what would be the best solution for us.
What i want to do is run 5 or 6 servers to begin with, and maybe look at running more later on down the line.
What solutions do you use and what sort of costs am i going to be looking at? Should i go with a good make for all my kit like HP, Dell etc, or will i be able to use openfiller(which is something i've heard of but never used).
How does a SAN work? is it a server with lots of hard drives in it? or is it multiple computers all brought together using one computer running something like openfiller?
Any help on this would be great, the sooner i get the hang of virtualisation the better.
