Ok. I'm a bit of a noob to Server virtualisation. I'd like a set-up as shown below - two physically identical boxes, running Hyper V Server, with a SAN storage attached. My question is, can I run my entire network (less than 20 users) on a set-up like this? I'd be looking at around 4, 5 maybe 6 virtual servers on the Cluster boxes. It'd be one Domain Controller (running AD, File Server, etc) and the other servers smaller tasks (email server; back-up schedule; whatever else; etc). We've not a big network but we generate a lot of data, hence the SAN. All suggestions welcome!
