How to make office server? (multiple keyboards/mice on one cpu)

post #1 of 17
Thread Starter 
How to make a small server where employees can access office apps like msword and firefox at the same time?

Server will have like 4 pairs of keyboards, mice, and monitors for access.
1. What OS is needed for that?
2. Do I need a kvm splitter like this: http://www.networktechinc.com/kmspltpc.html

You might be able to do it with virtual machines.
Plug all the keyboards and mice in, and assign them to the appropriate virtual machine.
As for the screens might be a bit harder, you'll need to have at least 5 vga or dvi connections (1 for the actual server, 4 for each virtual machines) You'll be able to do that by adding a couple of cheap video cards.

As for assigning the monitor to the virtual machine, I can't think of how to do it at the moment but it should be do-able.

It can all be done with Windows and VMware Workstation. You can also take the cheaper route with a Linux distro and VirtualBox.

Vmware Workstation:

VirtualBox:

As for licensing for the virtual machines I'm not sure how that would work.
Maybe someone will chime in with more information.
You would also need a pretty beefy computer with plenty of ram to run four clients.

Edit:
Thinking about my idea, maybe a bare metal Hyper Visor would be better.
But I don't know much about those

It usually doesn't work like that. What you're describing is similar to a "thin client" system, where the apps run on a server, but everyone needs a terminal, or a low-end PC to run as a thin client that connects to the server to run the apps. There isn't really a good way around that.

This can be done with Windows Terminal Server. However, that is kind of expensive solutions for only four systems.

KVM switches are really meant for making multiple systems work with one keyboard/monitor/mouse, not the other way around (multiple input devices, one system). The one you show is interesting; I've never seen something like it, but if you use that option, you'll probably need a semi-beefy main system so that you have enough RAM and processing power for four users with four virtual machines, and you will still need a software license for each user's copy of MS Office (you can't use just one license).

Also, the KVM you're showing uses PS/2 ports for keyboards and mice. Many newer systems may only have one, or even sometimes no PS/2 ports; keep that in mind unless you have a system you already intend to use.

Also, MS Word (and most paid applications) licensing explicitly cover virtual or shared accounts.

Can a 1090T and 8gb ram be enough to run 3 virtual machines?
They will only run msword, ms excel and a browser.
GPU could be a 5670 flex for 3 monitor support but I have no idea on how to split the video of different virtual machines, still researching on that.

I just thought that a single cpu would be more energy efficient and cheaper than building low-end sempron 140 workstations

Have you considered going with AMD E-350 mainboards? A single CPU might be more energy efficient. Maybe cheaper --but probably not easier.

This board might be the perfect solution for building small workstations.

yeah but the only llano cpu available in our country is A6 3650 and costs 120$
while a sempron and am3 board would only cost 80$

I have a similar setup (see sig) I can run up to 4 virtual machines. However they aren't running for a significant amount of time.
The CPU should be fine but 8GB of ram might not be, also there would the I/O of the harddrive to consider.
4 PC's running off one harddrive would make things very slow.

I would agree with LoneWolf it wouldn't be the easiest solution.
Especially if the PC fails. You will have 3 users without access to a PC instead of 1.
So in the long run it may not be cheaper, time is money.

The final decision is up too you.

At work, we use the NComputing X350 to split a single HP workstation into 4 monitor/keyboard/mice combinations. I think it's exactly what you're looking for

http://www.newegg.com/Product/Produc...82E16859325001

The performance seems decent, although an SSD would probably greatly improve it and it wouldn't cost that much, seeing as you wouldn't need a huge SSD to install Windows + whatever office-related applications you needed.

What you are looking for is a terminal services or virtual desktop solution.

Citrix has a variety of VDI products, and VMware has some VDI products as well. Your best bet would be to price them out for the 4 users and if it would be worth it. Having worked with ESXi for a while I am a bit partial, but if your VM hypervisor is Citrix, that wouldn't be a bad option to go with their VDI.

Also, this is a business, so DIY is never an option. Dell, HP, and IBM have fantastic support that is worlds above any component manufacturer.

SSD wouldn't help much; the big problem is network latency.

A kit like that is an option, however support will be slim to none, and administration options are usually lacking. That setup is more for your house, where you can have hours of down time and no one cares too much.
