Was wondering if anyone would be interested in hosting their mining rigs at a premier world-class datacenter?

I'm not referring to a "warehouse" hosting environment but a top tier datacenter with customers the likes of yahoo, financial institutions, etc. with proper cooling and security. They can run without utility power almost indefinitely if necessary and have done so for months at a time in the past (personal experience).

Currently getting quotes from a few of these type of data center. So far I have received a quote from the data center where I have been hosting all of my server and other equipment for over 8 years but they are on the high side.

Data Center A
$340/month per kW     (ouch!)

Data Center B
$290/month per kW

Data Center C
pending

My goal is to get the price in the $150/month per kW (ex: AntMiner S2) but would anyone be interested?

I've got a relationship with a miner friendly hosting facility now (if you're looking). Several options/configurations available, the popular rates are below:

Full cabinet – 20amps @ 208V is $799 a month
Full cabinet – 30amps @ 208v is $850 a month

Your pricing is good compared to Data Center A.

Cost from Data Center A (most expensive but the best in the area):

Full rack with 60A/208V and everything else is about $3400/month. 80% of that 60A is usable so 48A of usable power....or in watts about 10 kW usable.

3400/10 = $340/month per kW
3400/48 = $70.83/month per A

Does your offering include the full usage of the 20/30amps or do you limit to 80% of rated capacity?

I was trying to see if I can get pricing in the $150/month per kW or $31.25/month per A. Looks like you got close!

How about a 17.2KW usable cab for $3100/mo?
We have lots of power and cooling... we need your miners.
 

Best offer l got so far is 120€/kwh/month.

I'm looking at approx £750 for a full 42u cabinet with 8A (1.8KW) power presentation...  if you're looking though watch out for A- Hefty setup fee's and b-n nasty connectivity charges.  With mining you don't need a 10G lease line...

I could fit 10x 1TH/s miners plus a switch into a 42u rack but I have no idea if 8A (1.8KW) is enough power though  ???

My best offer is $1699 for 12kW per rack.  $500 set-up fee though...

$3100 for 17.2kW = ???

Not even remote close to enough power.  You would need 12-16kW with modern hashing hardware.

Agreed - 1.8kW is NOT enough for 2 miners  :(

Your 12kw rack is really just under 10kw usable, closer to 9600w really (80%). Our racks are 17kw fully usable, full 60 amps of 3-phase. 

$170/usable KW vs. $180/usable KW, so we are a little higher...but we handle your install and are full-service for miners.  What's the contract term, and how many cabs do you need?  We can probably match the $170/usable kw rate, but it will take some arm wrestling.

Who said it was NOT 12kW usable  ???  It is 12kW usable...

4 cabinets and 3 month term.

It's probably 2 -  30 amp 208V circuits, which isn't 12kw usable.... there's the 80% continuous load requirement that you have to abide by.  Data Centers nearly always quote installed power... unless you are getting quoted something else?

Yup, you need at least a 60A/208V circuit for a total of 12480W but most if not all DC's limit you to 80% of rated capacity so that gives you just under 10kW.

Thanks for the advice and I am a tad leery as well.  I am re-confirming now as I have always told them I am requesting USABLE watts per cabinet.

If it is 3 phase would 208V @ 60A be 208 x 60 x 1.73 x .8 = 17.2kW?

I've got hosting in Vancouver, BC for $400 a month.   Fully secured, cooled, 2400 watt cage.

Yup it's 17.2 kVa, which is around 17k usable watts.  Phase loading is VERY important, ideally you want to install in sets of 3 (one machine per phase). 

Also make sure there aren't other hidden charges.  Data Centers can play games with making you buy bandwidth from 3rd parties.  Are they supplying the PDU's or are you? You can spend anywhere from $200 to OMFG on PDUs so beware of the possible expense. The HP monitored 3-phase one we are running now was like $1500, but its super titties, remote monitoring, remote plug control, per outlet metered.

Make sure the datacenter REALLY understands what high density is all about.  The heat off your gear can and will affect other customers if they don't do adequate planning...

Happy to help also via PM; even if you don't go with us, we'll try to help keep you from getting screwed like we did on our first data center mining foray.

MWNinja,

Do you have a web site or should people PM you on here? Also, as for available watts I thought it was just Volts*Amps=Watts (ex: 208*60=12480). Where does the 1.73 come from?

The 1.73 is for 3 phase...

PM me, website, cloud mining, and other fun stuff is in the works. Ready in "2 weeks"

Ha! I cracked it.

I have a climate controlled sever room that I can use as part of a temp office space and they are happy for me to host as many miners as I can fit in there...  total cost?

£400 + VAT

I also get a desk with a 70mb internet connection too.... up and down ...for erm..  i dunno what yet..  but something! :-)


You should see it its terribly dis-organised about 100 old ATX servers in there already they don't really know what they're doing which works perfect for me :-)

Now it all goes down to mining becoming harder... how long will 10TH/s even at this low cost be profitable?  will we see 10TH/s miners or even 100TH/s miners come to market to meet demand..? will BTC zoom up in value making our little hobby still worth it...

Take advantage of it while you can hooliuk. When they see their electricity bill skyrocket expect some changes :)

I can host all of the gear you throw at me for $165 Kw.  I own multiple buildings that are all data centers and are pretty much empty with exception to some staple customers
that hold the centers in the black. :-)

We use the centers primarily for fiber optic hubs so its mostly patch bays and stuff but they are full blown data centers so I'm looking to fill them all up with bitcoin
the way we did in San Diego Bldg1.  Next I'm selling space in San Diego Bldg2 which is ready to go. Are you in need? Contact me I would be more than happy to
work with you to get you up and running.

FULL SERVICE for MINERS.

Well we'll see how it goes they have 180 businesses working out the building so adding another 40AMPs or so shouldn't raise to many eyebrows.

They have four of the same buildings within 15 miles of each other too..  so even a desk in each ...   40TH mining... ...  and with bitcoin starting to slowly recover..  i think its all about lap it up while we can...

Each Terraminer uses just over 9Amp @ 230v you 90+ amps per 42U cabinet

Looked around at Data Center Colocation for a while. In the Uk they only seem to offer a maximum of 32amps @ 230v per cabinet.

This is at the most 3 Terraminers which would be one very empty 42u cabinet !

We're making our own mining facility now with 96 Amps per cabinet balanced across 3 phases, raised access floor and climate controlled cold aisle.

Biggest problem is the sheer amount of power they need we're having to apply to the national grid to get the power cables upgraded coming into the building.

Typical data centers aren't really set up for mining hardware they're designed for task critical servers using around 3-500w

Contact me on skype, I can get all of your gear up and good pricing too.
