P.S. Btw do you think you can handle/cool a full rack of SP30s? I know that many people (*cough*jimmothy*cough*) were complaining about the fact that nobody can coll off a rack full of SP10s and you have more power there than a full rack of SP10s and I don't see any problem if you couldn't do it, but I asked just for the fun.

We're having no trouble with cooling. We should be able to fill that rack without a hitch. If there were something 2x as power dense than an SP30, we should be able to cool that too. I'm a little disappointed with how easy it's been.

I was doing some work on our router/server today, and I found the most comfortable place to be (as long as you have earplugs on) is inside the hot aisle, with about half your body in front of the SP30s and half in front of our half-full medium-density rack. That way, you can lean forward to get in the cool airstream if you get too hot, or lean back to take on the SP30 exhaust if you get too cold. Sitting outside the hot aisle in our DC is just too windy and cold to be comfortable.

From one of the machines inside that rack:

Mining Rate: 4528.75Ghs

Temp Front / Back T,B
21 °C / 63,66 °C

Socket Voltage
251/250 volt

Fan Speed
90

Max Watts
1340 / 1335

For our phase 3, we're thinking of trying to get around 5 MW of machines running in about 5,000 sq ft. That should be fun.

Most "high density" hosting facilities max out under 10 KW per rack. A rack of SP10s is what, 40 KW, and a rack of SP30s at 60 KW? So yeah, you'll have a real hard time filling a rack of those in a regular facility.

Our DC Will be able to handle ~15 per rack, only because they have empty racks to fill

Regular maybe, even though I have a feeling that it's close to doable. Not under optimal conditions, but possible.

@jtoomim One more question about the cooling for my personal knowledge. What you needed more for your super cooling? Money or knowledge? My guts tells me that the "custom" cooling itself didn't cost that much compared to the cost of the full rack filled with SP30 miners, but it's so efficient because of the airflow knowledge that you have. Am I right?

I received my 2 x SP30s yesterday, and installed them in my quiet rack cabinet.

These are impressive units! Definitely the "Big Boys Toys" of the Bitcoin mining world.

I got them all hooked up, and they were up and mining as soon as I logged in and entered my pool details. Damn, that was easy. I hung around for a while watching them, and stressed myself out a little bit when they stopped mining. I should have just walked away and left them to it, knowing that they do a series of performance stress-tests to find the optimimum operating speed before PSU/ASIC failure. Sure enough, they settled down into their optimum groove all by themselves, probably still adjusting as they have only been running about 16 hours so far.

These bad boys are the rockstars of my collection. Hash rate at the pool as at 16 hours:
SP30A 4.5 TH/s
SP30B 4.4 TH/s

On my to-do list:
* Upgrade the firmware to the latest version
* Install the rubber feet. I think this might reduce vibration noise.

In a couple of days if you would be kind enough to tell me how much BTC you average daily, I would be grateful.

no need to wait, you can plug in numbers here and see BTC/day
http://www.bitcoinx.com/profit/
4.5Th=0.1147 BTC/day (right now)

erm your only making $52.46 per machine in 24/h
you spend $7790
6000 watts will be alot per day to run
and your expecting to make a profit?HuhHuhHuh??

The cooling stuff was not very expensive. There definitely was some secret sauce involved, though. The electrical work was where most of our money went.

Correct. Yellow labels, I think.

I posted a video of an SP10 running in it earlier on this thread: https://bitcointalk.org/index.php?topic=521520.msg7194614#msg7194614

I'll take a video of the SP30s running in one too and post it up (different cabinet, different location). Stay tuned.

Nice cabinet.  Data Center quality for the soho.  What did you end up paying for that?

I bought them from a UK company, who shipped them to me on the other side of the world (New Zealand). You can see prices on their web site:
http://www.acoustiproducts.com/en/ucoustic_active.asp
The one in my video is the Wood panelled product (in Maple).

I'm an enthusiast, and enjoy hosting the hardware myself. I ordered the cabinets before super-cheap hosting like toom.im was available. Purely from a financial point of view the cabinet doesn't make sense. Beautiful product though, and the pleasure of owning them is part of what I get out of this hobby.

Wow, that's nice, though expensive, I'll nevertheless have to look through their website. Wink

When I was there tonight I believe the exhaust temperature was around 61C, next time I'm there I'll check again. No a/c, the air is drawn in from one side of the building and vented out the opposite side.
