Tom's Hardware KVM Roundup 213
nexex writes: "Tom's Hardware has a new article with a review of several KVM switches. I have considering buying a KVM switch as I seem to collect/use more & more computers, I feel left with little choice :) While I have several friends who have taken the plunge, they have all spent wildly different amounts on them. Granted price plays a great factor on the features you get, but how do you know which one is not going to end up letting you down? If you end up with el cheapo, you will most certainly end up regretting it, as this device will be carrying the signals of your primary input and output to your systems."

A few months back I was looking through uBid.com and found a 4-port KVM that had plenty of features (more than the Belkin, at least) and even included 2 free cable sets. I had never heard of the brand (Genie), but I figured at only $100, it was worth a shot to get all my machines hooked up to the KVM and thus ditch an extra monitor. And luckily enough, it has performed flawlessly. It still irks me to remember how much I paid for the original 2 port Belkin (almost $300 a couple years ago) now that this "cheapo" one is working so well, but its also good to see the good features and stability of the higher end KVMs coming to the lower end of the price range.

Wouldn't it be nice if you had a box you could tack onto your existing system to pump the basic IO over your existing CAT-5 wiring? My ideal unit would have the following
Input jumper for power switch control
Input jumper for reset button control
Light sensor for power light
Light sensor for HDD light
Light sensor for Link light
Light sensor for Act light
Serial PS/2 port for keyboard
Serial PS/2 port for mouse
15-pin RGB port for monitor
Here's how it would work. You mount the box on the back of your server unit and connect your power and reset buttons to the unit and connect the unit to the reset/power jumpers on the motherboard. You stick the light sensors near the respective LEDs. You wire up the KVM to the unit and optionally plug the local devices into the unit.
Now, the unit is a little linux box that takes the input and sends it over the network (now we're using VNC) to my remote session. The bonus is that I can still see the unit if it's crashed (the VNC service or the whole dang box). I can boot into the BIOS and make changes. I can run utilites and so on from DOS sessions. Plus, I can click a button and reset the box, or power it down. If I connect to the session and see no image, I can see if the power light is on or if there is any hard drive/network activity.
I can think of about a billion times in my techie lifespan that I've wished for such a device. Yes, I know there devices you can use to remotely power off a computer. Yes, I know I could setup a webcam to monitor some lights. Yes, I know VNC gets me most of the way there.
But it's not cost effective to buy one of these for each server. I would rather have one box that could control 4/8/16 boxes. It's just a standard KVM with some extra inputs attached to its own dedicated Linux box!
So please, Linksys, Belkin...whoever...can't someone please build this, or show me a link to something like this?

I forgot that floppy swapping is another big reason I've had to make wasteful trips to the server room, which I would like to eliminate.

Belkin, Raritan, Audio, and Game Consoles (Score:2, Interesting)
The Belkin OmniCube is crappy, doesn't support high resolutions and decent refresh rates, and then it broke so that I could only get signal to one of the computers. Yay! A signal degrader instead of a KVM. The place I work at also has larger Belkin KVMs and they're not working like they're supposed to. Cheap and a waste of money.
The Raritan SwitchMan is exceptional, and works wonderfully. However, you need to use special cables as it wants Male to Male instead of the usual Male to Female. The cables aren't cheap. But I can run high resolutions at 85Hz, and there are some programmable features. You can also chain them together. The more expensive Raritan models support some even more interesting features. The only drawbacks are the somewhat more expensive price, and lack of support for Macs and USB.
I've also found that in addition to switching the keyboard, monitor, and mouse, I want to switch the audio. So, I purchased a Nady MM4 mixer from Musician's Friend (about $80 after shipping) and now I can also mix four audio sources to my Desktop Theater 5.1 sound system.
Something else I think should be mentioned is that you don't have to use KVMs (or the audio mixer) only for computers. I have my Dreamcast plugged into the Raritan KVM and Nady MM4 mixer for use with the VGA output. I plan on getting a PS2 and sending it to the same port of the KVM via a breakout box and video switcher (and my N64 at that point as well), or to a TV tuner card and then to the monitor, plus it's audio signal to the mixer.
The only thing I really want but haven't seen anywhere is the ability to use Macs and PCs alongside the gaming consoles. You can't really interchange Mac and Windows keyboards, but I'd love a KVM that I could do that with. If it could just interpret the Command/Apple key on the keyboard as the Windows key, and vice-versa, then I could put them all on one keyboard, monitor, and mouse.
