I called an electrician and told him.. He's the one who advised me to add these new sockets. I'm guessing he's not a qualified electrician.
Is there anything in specific I should tell the electrician?

I'm not good at electrical wiring. Maybe someone else can help you, but I would tell him: "Yo dawg I need to plug 6 cables that will suck 1500W each. Do your stuff and I'm paying!".

haha.. Cant I just put an extension with 6 extra sockets type thingy and connect the machines to that?

You use a PDU (big ass power bar rated for the proper amperage) and plug your power supplies into that. I have 30 amp PDU's connected to a 240v outlet. This allows me to run about 5800 watts of the single plug. Much more cost effective than pulling more copper and having multiple outlets at the wall.

Ok, I'll look into getting a 30AMP PDU in London. So i can connect that directly into my socket. Will this be enough to plug 2 or more SP-30s?

Not at these power draws... I didnt see above, are you in the US or elsewhere?

Im in the UK

You want to go with what wpg recomends, your going to want dedicated 20/30A circuits @ 220/240 for each SP30 you have, cheap NEMA l6-20r or l6-30R pdus can be had for less than $100 each

Looking forward to deploying some of my clients machines today... going to be doing some large scale testing with the SP30/31 and p2pool, going to see if we cant add a few PH to p2p over the next month or so.

Anyone have good ideas on monitoring software /scripts for these? We use a couple of in house options but want to see if anyone has better ideas. Generally SPs are amazingly good and stable compared to other miners, but better safe than sorry.

Ok.. Hosting seems to be bit expensive. I have allocated some rack space in my room near the window. And also with my air-con. I'm not fussy about the noise. The only issue now would be the power coming off the wall. I know London sockets support 240v. If I do plug two of the units will there be any issues like the units blowing up or anything?

What is the worst that could happen? Just my trip would be turned off right?

I can change the electrics in the room. I had to manually create extra sockets which I fed off another power wire.

You should call an electrician and inform him about your plans. The cost of re-wiring should be minimal.

Each SP30 will consume up to 7 amperes and in an environment that does not have proper air flow will reach 80 Celsius easily on the back of the box ...

I just vent my miners out a window. The screen protects the miners from a squirrel making a nest in them. No need to pay for cooling. I've done it for over a year now with no issues other than noise, but these days I'm running S3's which are very quiet. Probably wouldn't work with the jet engine noise level of the SP units. Unless you live away from other people who would complain.

I have done a similar setup with 8 S3s, just pointed the end to a higher cfm fan, and it helped a lot. Temperatures at the intake side never reached more than 27°C.

Then again, spondoolies gear is probably a little more sensitive to heat, so simply extracting hot air will only work if the intake air is at a decent temperature, or you risk loosing some hashrate.

Whats there to play with, you want them to be up as long as possible. Get it hashing and then dont touch that mofo unless you have to!

I'm working on a small code change to enable the unit to log a small hashing data set to a database and set up alerts on it.
Without SSH access to it, I can't do that and test the wereabouts .. here's a sample output ..

I'm lnking the local hashrate value, with the detected pool hashrate and 1m-15m averages, with the line voltage, amperage at the wall for each PSU, intake and otput temperatures. The CPU load is there so that the script logging the data does not affect the computing capacity more than it should .. (I sanitized my serial number)

I hope that some hosting companies will use it to monitor all their SPT miners, they can even bill by the recorded KWh .. or as a logging tool to enforce Service Level Agreements

if not, I'll still make good use of this. There's a lot to play with .. especially if you want to process SP10, SP20 and SP30 data with the same code.

Ok I will get them sent to a different hosting facility. Which country do you recommend for cheapest electricity and better service. Can I change the delivery address after I have placed the order for the SP-30's? How will the hosting work? The company will give me VPN access?

My take .. Keep one home to play with .. if you intend to do that. Once they're in the data centers, there's limited access to them.
if you host in USA, you won't need to pay VAT when you import the units you intend to send there .. I dunno about Iceland

Yes you can change the delivery address after you place your order. Just send an e-mail at sales@ and ask for a confirmation.

I use Advania and they provide VPN at request, but you need to have a 6 months minimum contract, but you pay monthly. They are a bit pricey, but they have better rates than your UK power rates. If you want cheaper power I would suggest bobsag3 solution. Take a look here https://bitcointalksearch.org/topic/hw-hosting-directory-reputation-622998 for various other offers, but these 2 are a good starting point.

Wow. Noise can be mitigated by buying an expensive ($5K) cabinet, but heat?
people just look at the production numbers and don't think about heat, which is a MAJOR issue (for home).

The Guy that builds these open racks for GPU mining also has a sound reduction cabinet for rackmountable gear for under $1K, and it works quite well.

THERE is no cheap hosting in London, UK electricity rates are too high.

Get spondoolies to send the units directly to a hosting facility of your choosing, that way you will not have to worry about VAT (and additional shipping costs).

Look for the hw hosting comparison thread in the service discussion subcategory of the marketplace.

see my edited post above for locations. Iceland and some US sites are comparable. Yes, you can change address with spond, but need to do it before they shipped, obviously. Access varies (with VPN or without), but some even give you a dedicated IP address (michigan colocation).
