[ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs

[Biffa]

I run my SP30 with a static IP (internal 10.10.0.100) because it was the one the unit leased for the first time and I liked it . DHCP is better though for hosted environments and multiple machines.
Moreover I am the one fixing things if something goes bad with the network here  .. one small 1u server in a corner rack drives the whole setup, I won't complain about space, usually you run out of power before you run out of space.

Does the unit works well with static IP addresses? which pool are you using?

You might be able to use a small nettop and configure it as a NAT/DHCP device and hang it in the side of the cabinet beside your SP30.

Yeah, I also use data centers meant for internet hosting and they give you a static IP block with a gateway IP address. This doesn't work well with Spondoolies and KnC default setups. However, I have space for a NAT/DHCP 1U device.

Thank you Soros!

I have static IP's on all of mine on Eligius with no issues.

Ok, because on my miners with static IP I was not able to get them working... always got:

Stratum connection to pool 0 interrupted.
Lost X shares due to stratum disconnect on pool 0
Stratum from pool 0 requested work restart

I tried different pools ... as soon the machines were DHCP all fine. Which firmware are you running?
thx

[wh00per]

I'm on Eligius .. and 2.3.44 firmware. I put in place a port-forward setup for SSH and HTTP. The stratum goes out via NAT/MASQ.

If I understand the pools using stratum protocol right, the pool requires work restart if there are no shares posted back over a given amount of time and they reallocate the work to another worker. If you still submit results after a given time, they get rejected Therefore, the miner is notified by the pool to restart the work with the new work allocation.  
This may be due to bad luck (i.e. your machine could not find shares over the required pool difficulty for some time) or traffic shaping (if your DC does that to conserve bandwidth, and your share results do not make it in time back to the pool).

On another note, I found out that I can't use the "switchpool" command in cgminer API, on SP30. It was originally programmed in (i.e. "promotePool" JS function), but commented out. What happens, is that when the 2nd pool gets "promoted" in cgminer, the watchdog monitors connectivity with the first pool. It restarts cgminer, which goes back to the first pool after restart Funny. For some time I was browsing the code for the MinePeon donation code, which was originally switching pools for the configured amount of time you want to donate your hashes to MinePeon (default 0).  The watchdog though, will restart cgminer on the "0" pool as soon as it has connectivity to it. Therefore, the "donation" thingie does not work with the default setup even if you want to.

on a side note i was messing around on the net and this sounds interesting for you folks in hot areas

the key point is they accept bitcoin so you BTC whales out there can really take advantage of that

Unfortunately, even with the latest developments, solar power (photovoltaics) is the most expensive renewable energy at this point in time as $$/MWh goes. And it runs twice more expensive as the next in line (wind offshore), if you're off-the-grid, mainly because of the battery costs.

yeah the battery costs are high , some people have success chanining together a ton of cheap car battries though if you are a do it yoruselfer

zvisha, have you guys underclocked SP10s? If so can you give us roughly power consumption for whatever settings you tested?

I think this will help SP10 owners to prolong their mining if they can get higher efficiency. Just like how Bitmain did to their chips

  There is no pleasure in having nothing to do; the fun is in having lots to do and not doing it ..

It is easy.
Set low starting voltage and slightly higher top voltage. See the watts it is using in the "asic stats" page. Divide the hash-rate to get GH/W.

I am not near SP10 to provide numbers, but maybe someone here is.

P.S. The actual GH/W at given voltage will depend on your batch too.

I have a May batch SP10. A few months ago I ran it in "quiet" mode for about a week and measured the power draw at the wall:
~1.17 TH / ~910 W / "quiet" mode

=> 0.77 J/GH

I went to 1.5.6 on my two SP10's and hashing speeds dropped from a solid 1.4TH to a 1.38TH.

Can you overclock it a bit ? Some 20GH it's normal variance for 1.4TH, I might say.

And a difference of 12 cents per day.

With the eligius.st luck lately .. I wish to be only that much.

[nhminer]

Can anyone report on their experiences with the SP30 on p2pool please? Thanks.

We currently have about 230 TH/s mostly comprising SP30s on p2pool. They seem to work with p2pool just fine.

Did you get your local p2pool up and running?

is there a thread somewhere on this forum for alternative power methods?

As i read last pages of this topic this project of 6000 ghs get out soo this equipment goes to 4500 ghs thats great my question since im new and i wanna buy 1 miner ,those 4500ghs mines how many bitcoins currently ,i know difficulty is getting higger week by week.... and to send this product to Brazil how much it will cost just to send it the taxer here goes around 60 to 75% besides the cost and worth of the product soo i need to know how much it will cost to send ,all people o know are paying those taxes in Brazil ,
This machine comes with the scrypt and i can choose any pool i mean look,ghash.io im here registed and ready to mine ,or there is a restrict pool to mine as the place you belong ....


the main question is the machine is with scrypt installed ?soo all i have to put is the stratum my id and worker and start? is that or something else do to do mine bitcoins thanks and sorry im new and in portuguese there are no such support better then this forum knowledge users as companies .

No offense but you should use Portugeuse to English Google translate it you want to get your point across. Your English is not very good.  

I think I can answer a couple of question though.

No, you can't mine Script with this machine. It is for SHA-256 only (BTC, PPC and a few other virtually worthless coins).

You can mine at any bitcoin pool of your choosing.

I have absolutely no idea what it would cost to ship to Brazil. But if you have to pay 60-75% import duty (!) on top of the hardware cost and shipping you might as well forget mining. All BTC mining equipment is marginally profitable under the absolute best circumstances... super cheap and reliable electricity, no VAT or import fees, a suitable location to run noisy and hot hardware and the most efficient miners bought at the lowest price possible. And then you still have to hope for low difficulty adjustments.

main point i asked how many bitcoins this machine SP35 that looks to have 6000 ghs can mine monthly...... as i say at test sale those transport would cost me 300 dollars soo 4200 dollars more the taxes that for sure i will have to pay to get this SP35 will cost me around 7300 dollars....
 anyone knows the weight of this  thanks

Huh ? Why not ?

[s1gs3gv]

Probably a lot less than it costs you

Mining is a dead game, you won't ROI with such pre-orders that take 2 months and difficulty rising the way it is.
