Which Motherboards for Headless Unix Servers? 33
nettdata asks: "So I'm a 'Sun' guy who's looking to build a Linux server. I've got everything picked out except the motherboard, and I need help. I've gone through some hardware sites (Tom's, etc.) but I can't seem to find a 'top 10' list for what I need, so I was hoping some experienced people in the Slashdot forum can help me cut to the chase. This will be my home server, so I want it to be as inexpensive as possible while still being something that will perform well. (Champagne taste on a beer budget). It will be a headless box, so more than anything I want the ability to do command line boot/BIOS control via the serial port to a VT100 session like I can with my Sun boxes. (This will be done via my handy dandy PortMaster). Lights Out Management (LOM) would be an added bonus. Google, Slashdot, and ExtremeTech searches haven't turned up anything usefull. Any thoughts or sites?"

Just to confirm, though... is the entire boot process redirected to the serial port should a keyboard/mouse/monitor not be attached?

I wish supermicro would bite the bullet and make AMD boards...

It works sweet.
BTW, any Linux box with a serial port will allow you to connect a VT-100. The Linux Kernel can handle that no problem. I've got a 486-33 Thinkpad running OS/2 and a term program set up as the console on the above described server.

That's the kind of functionality I'm looking for in the non-Sun world.

Note that it's a bit noisy, so if it's going to be a "home server" you probably want to put it in the basement.
Or you could just slap a "PC Weasel" [realweasel.com] card into a regular server, and get console redirection over RS-232. [Note: despite the name, this is a real company and product AFAIK. No relation to www.realhamster.com.]

"The bottom line with the console redirection, is that it's really BIOS redirection. It's only possible to see what's going on until the OS takes over from the BIOS"
Well, that's not really a problem because it's only the early boot stuff (BIOS, SCSI card setup, etc) that needs hardware support. Once your bootloader activates, it can just talk directly to the serial port without needing the "redirection" layer.
OpenBSD is particularly good at this. If you take a standard installation boot-floppy and create one file "/etc/boot.conf" with the line "set tty com0", it's possible to do a complete network-install of the OS onto a new server without ever attaching a keyboard or monitor.

Serial BIOS is the hard part to find.. (Score:3, Informative)
The problem is (of course) finding a board that has that feature. I'm afraid that most boards in the 'budget' range will not do this.
If you have a bunch of them at a colo, you can daisy-chain the serial ports, (So the console from A is going into B, the console from B is going into C, and so on until the console from X is going into A) The only way to totally lose a machine is to lose ALL of them.
You can't find it . . . (Score:1)
Someone else mentioned the weasel, it does exactly what you want, but they aren't cheap.
PC MBs aren't going to give you LOM or BIOS via serial.
Either get a second-hand Sun, or learn to live without this stuff (or fork out the $$ for the weasel).
Living without it isn't that bad. How often do you really need to mess with the BIOS? You can get arount boot options with "lilo -R [label]" (change the default boot image for the next boot only) and if it never comes up just pop in your boot floppy, get it up and try again. Worst case you have to schlep a monitor over to the system.
Welcome to the world of cheap hardware!

But we're talking beer budget, remember. Sure, you could buy a PowerEdge with a DRAC, or a high-end SuperO setup, but that isn't really on topic is it?
I mean, I know I said you can't find it. Like every infatic statemnet (including this one) it is fundamentally false. If you are going to point out "answers" to questions that don't meet the original premise of the question you have a never-ending task ahead of you. And if I try to preemtively point out every possible situation like this my posts would never end.
To summarize, I stand behind my statements within the given problem domain.
Anyway, if this guy really "needs" all these features I really think he is best off with a used Sun box.
