We are looking into a new Remote Desktop Services / RemoteApp server. We are considering running our most frequently used programs on it. I think we'll be able to spec the server out nice enough to handle the processing load. What I'm wondering then, is if there might be a bottleneck at all the information traveling through one network cable to the server. All of our NICs and switches in the office are gigabit. We are running Cat5e cable everywhere, which, from my understanding, should be giving us gigabit benefits. So, again, I'm not so much worried about speed as I am bandwidth when it all has to go through one cable. Our office only has 20 users, but as I understand it, RDP essentially sends a refreshing picture through the wire; and I figure that with 20 people all requesting refreshing pictures from the same NIC, that might get a little bogged down. Should I even be concerned about that?
If so, what is the best way to take multiple NICs and make sure both are taking in and sending out information from that server? Ultimately, I feel like the cleanest way would be to keep just one IP address if that's possible. Most of the articles that I'm seeing online are only dealing with 10/100 networks, and so they're mostly looking for increased speed. And again, maybe gigabit can handle 20 simultaneous RDP connections more than fine. Any thoughts?
