Ok so after a recent screwup on my server [dont ask] I had to get a kvm put on it. and I must say these things are SWEET!
What they allow you to do is access the server as if you were in front of it. This model is GREAT because it even allows me to add a iso image to the server so I could perform remote os reloads if I wanted.
Price? Well lets just say I cant afford them 😛
