Why not use immersion cooling instead of an AC?

Novec is only $250/gallon and I think you would need about 2-4 gallons per sp30.

It is a nice a/c, but IMHO It is useless to waste energy cooling something that is so energy efficient.
Also, those a/c's are not designed for a 100% duty cycle, as are for home use.

You either decide to send it to a DC, or build a nice polyurethane kiosk and use at least 4x 40w industrial fans with extra filters used for electrical cabinets.

It will do the job and keep also a low energy consumption.

@zvisha, Thanks for replying.  I was wondering about access and got more concerned when I saw the screenshots of customers miners in the DC.

I was afraid this was going to be the answer (needing tons of separate VLANs) based on the functionality of the start. page assuming it was on a lan with all the miners.

That said, offering monitoring for your customers is a nice service and will appeal to many.  

Argh - I see my mistake.  That is the 33K not the 15K tripplite unit.

Apologies...

Also, you can have up to 5 zones (maybe 8 ) with the new Mr. Slim systems. I am having my miners hosted, but I am interested in these for other reasons.  The outside fan is almost silent, and I saw these operate, for the single unit cooling may take a little as 1 amp.  I want to do more research to see if they have a system with a return.

Thank you very much for your further information.
If the system can detect miner downtimes and technical parameters it should work very well.

I think he is talking about a specific model of (portable) AC units, not one of your miners

Hi
Are you sure about this number?  
How did you measure 1500W? At what voltage and with what tools? How much hash-rate do you get from it?

We have SW limit for ~1370W at the wall for 220V, and usually we are around ~1350W in turbo mode. In FCC tests we never passed 1370W at 220V.
We tested the PSU up to ~1390W, so I am surprised it works at 1500W.

Here is Dogies report with 1374W as his top power:

I recommend this : http://www.amazon.com/Mitsubishi-Single-Zone-Split-Conditioning-System/dp/B0060OU3DO/ref=sr_1_3?ie=UTF8&qid=1399297076&sr=8-3&keywords=mitsubishi+split+air+conditioner

It can be used for home if you no longer mining.

Always get Mitsubishi system, the best split system bar none

Easy to install, and heatpump is outside for best efficiency

Hi.
We are supporting 2 different options:

Recommended:
We are developing our custom monitoring system for our DC that will allow us to monitor performance of all hosted miners. All those monitored miners will be sitting in our VLAN, behind firewall and NAT, with our monitoring tools running in the cluster. We will update the FW, monitor rate and temperature etc`. We also have a technician in the DC to handle issues, HW malfunctions, do SW upgrades etc`. The user will be able to monitor his hash-rate on the pool side, and he will let us know of the wallets/pools via mail correspondence. We recommend pools that don`t require login, so it can be monitored by us and by the client.

Not recommended:
If someone REALLY insists to monitor his miners himself, we can put his miners on separate VLAN in the DC and give him access to the VLAN, but I really don't think it is a good idea from many points of view:
All such VLAN based miners will be on separate network interface (so they can not abuse the network or DDOS other miners), but they still can effect each other.  We will not be able to monitor them (since users can shut them down, restart, change mode, set custom IP etc`), the user will have to manually do SW upgrades, and it is much less secure (someone can access your VLAN by stealing your key).


So I really hope the users will prefer the fully monitored solution, which is a much more attractive package.

You mean the AC? I thought its for datacenter only,  did you measure thro PDU?

Search to know what BTU means b4 asking repeated questions (which is already answered in the quote), makes you look like a lazy idiot.

You always need a vent to the outside where you can pipe out the hot air which is generated by the AC you are running.

Mkae sure you have exhaust as well.  They pump out a TON of heat.  They pull ~ 1500W at the wall (I have two).

what about this beastie....less then 600 bucks i think it was

@spondoolies

Does your hosting package include public ips for management of the hosted units or is some other system used for miner management?

Yes , that would do the job for sure, but your bill would go high to the sky.
It consumes alone around 3kw.

I would suggest to build a nice small insulated kiosk and use fans with filters to circulate the air.
You can leave it at the balcony.

We charge $225/month on the SP10, with a 1 month minimum, and 0 setup fees. The $399 was a typo on my part.
We can currently offer $325/month hosting on the SP30, with the same 1 month minimum and 0 setup fees, and we are actively expanding our offerings to offer the lowest price possible to our customers.

Setup fees and time minimums are there to offer the lowest price per kwh.
But i would love to hear you hosting fees.

Can you compete with WA hydroelectric power, 290$/month sp30 hosting?

The last time i heard you charged 399$ per month for sp10 hosting, or double the price spondoolies themselves are offering.
That seams a bit excessive, dont you think?

That will also include a 24/7 SLA and professional security, high density cooling etc....

Even for the SP10, we have found that most of our customers choose to host with vs taking delivery. I can imagine that will only go up with the SP30- and we offer hosting for those as well without pesky setup fees or time minimums.
