Project : airchive - 25Sep06
I have decided to make a file server/download box for home.
I called it project airchive because airchie + archive = airchive.
I wanted something with redundancy (raid 5) and silence (HDD suspension) and cooling (immersion cooling using Fluorinert) and minimal power use (Epia 13000).
So far I have bought the hardware (Epia 13000, Promise SX4100 raid controller, 4x400GB Samsung HDDs and a 270W mATX Enermax PSU.
I will post pics shortly as soon as I get them upped to my webspace.
<EDIT>I have created a gallery here where you can see the full-size pics.
Please use this thread to post comments/criticism/encouragement/advice so I can keep this one only for pics and updates.
Thanks in advance.
OK, here's the first pics of the hardware sitting on my desk at work.
Ready to fire up as soon as I get a minute...
OK, I have run into my first snag already.
The Epia doesn't have a floppy drive header and so I can't install the raid controller drivers during install time (press F6).
Is there a sneaky way around this?
Thinking I might have to slipstream the drivers into the XP install?
Any better/easier methods?
Grrr, coulda sworn I'd posted.
Slipstreaming is the best way, use http://www.nliteos.com/ the other way is to use something like a USB floppy drive.
Nice one, thanks Doug.
I just found a USB floppy at work so I'll prob use that.
Do the USB drives work like normal ones for the XP setup process?
So annoying that we still need floppy drives these days...
I think they do, never used one personally, I prefer slip streaming, it makes it a lot easier if you need to reinstall as each of my XP licenses are linked to one machine.
USB drives are available for Vista if you want to try that.
Slightly Ninja edit:
Can't see how much RAM you have on that board, if you aren't running a lot (256MB) you may consider using something like Damn Small Linux to do it all.
Be carefull my friend I learn a lesson years ago, HDs don't like to be upside down, will be a shame to damage those babys. I really gonna keep an eye in this project.
hehe, well, we'll soon find out...
Got it booting as we speak.
Funny seeing the raid controller BIOS reporting one logical disk of 1200000MB!!
<ultra ninja edit> it worked!
XP setup is formatting the huge partition now...
did i read that right
4x400gb harddrives. !
Its a redundant array, if one drive fails you don't loose your data as the other drives store portions of it.
not quite, if its a striped array, which it seems to be if he has 4 X 400gb...if it was mirrord or 0 + 1 or 5, then there would be redundancy, but as it seems to be striped there is no redundancy....if one drive breaks, all data on all drives goes iirc.
nice amount of storage though
Hehe, seems to be some wires crossed here.
Its in raid 5, so the capacity = size of drives * (no of drives - 1).
So, 1200 = 400 * (4-1).
So 1200GB, or 1.2TB.
Guardian, its worth noting that raid5 is also known as striping with parity, so even though its a redundant array, it still uses striping.
Anyway, its all up and running now.
About to put some more pics up on the album...
I finally remembered stuff todo with RAID. Looking forward to see how u run this as I want todo a similar thing.
After toying around with this throughout the day while at work (its on my desk right beside me atm), I've got it set up and working.
Running XP Pro SP2.
Had to take the HDDs off the top of each other.
Thought it would be a good idea to stack them to keep things tidy and use a little packing between to prevent any accidental shorts.
I didn't think of the heat aspect til it suddenly ocurred to me and I did the finger test.
I almost melted my fingerprints off!!
So I destacked them as carefully as I could as they were about 50% through formatting at the time.
That's why there's a thermometer on them at one point, was trying to measure the temp.
Max I measured was 37degC but without a decent contact between the HDD and the probe.
So, on with the pics!
1200000MB!! Ching Ching!!
Yaay, the USB floppy drive worked as it should for the raid drivers.
w00t! Never seen XP measuring in TB before!
Larger pics are available here.
Comments etc can be left here.
Where'd u get the HDD's mate? how much were they?
BTW, looking good!
Its all running nicely now.
XP Pro booting off the single 1.09TB partition.
The Epia IDE and SATA controllers are now disabled.
Works well so far.
Just need to find some half inch thick acrylic for building the case now.
curses! i have just done some maths ( i hate maths) and it turns out that:
4 * 400 = 1600
4 * 400 = 1200!!
i think im going back to bed...
lol, I did wonder where the confusion was...
Lack of sleep is a killer...
The going rate for the 400Gb Samsung HDD seems to be about 80-85quid at most online PC pushers.
