Hi All,
I am new to VM so here are some questions.
Our company plans to purchase 2 VM hosts (clustering). Their plan is to migrate EVERYTHING (4 physical web servers, 2 Mail servers and 4 SQL servers,...) to VM.
what i concern is putting web and db server in one host. do not think this is a good idea, but i cannot provide the reason.
Also, any performance issue? what will be the best practice
thanks in advance

All depends on the resource load. How are you sizing the new VMs? Have you stress tested first? Do you have historical perf counters (CPU, Memeory, and I/O in particular)?
Virtualizing has many advantages, but you can't just guess when migrating, unless you want a lot of headaches later. |

thanks,
so besides resources concern, any security or network issue to put web and db servers in one VM host?
