"Mmmm hashrate" indeed...

Mmmm hashrate
Not mine.
QG
So thats where all the money went...
This is a client's, not mine.

There are about ~190 machines total, not sure if all of them made it into the pic.
~855TH .57KW

how are those wired? looks like PDU plugs coming down from above, but I've found that a 30A PDU will usually have only 4-6 of its 20+ outlets occupied by miners - making them cost-inefficient somewhat

50A PDUs, I got a screaming deal on them and supplied them to the DC.

Humm  487 KW.  At .10 per KW his electric bill alone is 35K per month.  Making about 350 BTC per month. By December that number will be down to 150. Hope BTC doesn't go below $200. Not going to ROI.

Im pretty sure he got a decent discount on that amount of SP's.

The picture is from bobsag´s hosting facility, he therefore doesn´t own the majority of the shown miners.

It also looks like his thermal engineering isn´t optimised to the fullest extent, as there is a significant amount of unused space in those racks.

Hes already pulling a lot of density. Unless he can somehow duct out all of the hot air, im pretty sure hes capped to capacity due to not having a hot/cold isle containment.

Well, building any datacenter-like facility without hot/cold aisle containment is both inefficient aswell as outdated.

It might be cheaper in the short term, but the increased footprint aswell as less efficient cooling and miners not profiting from optimal temperatures is more expensive after 6 months.

I guarentee that those Sp-30 miners are being properly exhausted.

9 SP-30 miners is about 30kW in a single rack, which is a LOT. If there is not some sort of exhaust fans located directly behind those racks than that building would be absolutely sweltering without a hot/cold aisle config.  spreading out the miners means lower temperatures for better hashrate, and the benefit of getting even an extra 500GH per rack that way more than covers the cost of buying extra racks to fit all the equipment.

IMO, the setup is pretty ideal - judging by the size of the building, theres not much harm in taking up a little more space with extra racks

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461 also selling 6" M-F-M PCIe splitters and PCIe-PCIe

I obviously didn´t mean to say that the units aren´t sufficiently cooled (or the walls would start melting at such a high density).

I only stated that it wasn´t optimised to the fullest extent which I think is a fair comment to make.

This can be seen by the empty, not sealed spaces between units, effectively creating "holes" in the hot air containment system (if this exists behind the units, which cannot be seen).

If anyone wants to share their unit temperatures inside this facility, feel free to do so.



A good example of an optimised hosting facilty can be seen here:



When the racks are full (which they are to my knowledge) the lower static pressure caused by the exhaust fans in the hot aisle actually increases airflow through the units, outside air is cooled by evaporative coolers.

Jtoomim´s system seems to be a little more complicated but such a high density without any active AC is astonishing.

The footprint is smaller and the amount of hosted hardware is higher than in bobsag´s facility.

The tempurature on those units are all about 25-27c / 75C in/out. There is more than enough cooling, the reason the units were spread out was more because of PDU limitations than anything.

Is there some hot air containment or is the whole facility cooled as one?

As stated in a previous statement, there is no wall behind those units, its literally a wall of exhaust fans. 100% of the hot air is kicked out of the facility.

Impressive!

Instead of massive aircraft hangar type DC's, the long, narrow building with wall-o-fans and racks on the long outside walls seems like the most efficient design.

Hey Bobsag! I'm still waiting for my refund that was promised to me more then 3 months ago!

My order was cancelled in May but you still shipped it to me 6 months late, I've refused the shipping and you will soon have it back.

All I want is my $800 back wire transferred or in BTC so I can quit annoying everyone and spend it on something else.

I tried to contact you/minersource multiple times in several ways the last months but I'm constantly being ignored. I'm a paying customer who trusted your company now please do the right thing and send me a refund.

I've filled a complaint with the BBB, next step is the FTC, my order ends with ..4732

yup! about twenty from the original pack and the rest from the "we dropped the price so here's a discount" buy.
