Hello
Can I order the shelf somewhere US/Canada?
Topic: Antminer S9,S9j,S9i / S9K,S9SE Rackmount Shelf (Read 7695 times)
PMed
Im in the US. Pricing on 3-5 including shipping? Pictures?
what is your location?
We have a similar frame for the newer PSU's
We have a similar frame for the newer PSU's
interested in these also. I'm in europe.
I actually could have just used some of these if the price is right. Anyone able to source these or make a good copy? How much for 5-10 units to start, with the possibility for more orders?

Are these still available?
Thanks, graymatter, for a very thoughtful reply. I will quote it for my future reference.
I guess we are most familiar with the opposite corners of the data center business space. You seem to be more of a greenfield guy hiring a temporary workforce. I'm more of the brownfield guy preferring to work with employees, both part-time and full-time, and maybe hiring contractors also keeping their own permanent workforce.
I'm particularly glad that you've mentioned that I neglected mentioning fire protection when using improvised fixtures for racking. This is again probably issue of working at different corners in the same large business space. You seem to have experience with dry climates whereas I'm familiar with moderate ones, where the main danger to the cardboard and wood is moisture, rot and other living things, not fire. As a mostly-brownfield person I'm mostly familiar with too sensitive and too wet fire protection, completely unlike the case in Thailand.
The two things I completely don't buy in your scenario is "10 minute MTTR" and "1 person working 20hr/week". To me they look like clear warning signs. I've seen many facilities making similar claims, they were seriously under-maintained. This is one point of the checklist that our buyout team uses: carefully inspect the facilities for the sign of rushed maintenance work: dropped washers from the rack-mount screws, whole rack-mount screw kits still in their plastic baggies, entire cable assemblies dropped on the floor and replaced. It is particularly important with the rack-mount case designed like yours, which has contiguous bottom, which make it additional "floor" to drop things on.
The room with long aisles like in one of your original photos is obviously unmaintainable by single person, it is a physical impossibility to replace equipment there by one person. It requires a work-team, probably equipped with walkie-talkies to actually productively work while the facility operates.
The opposite of your neat greenfield build out isn't a chicken coop. It is a brownfield deployment opportunity like the classical https://en.wikipedia.org/wiki/One_Wilshire .
I have no information on how good is your estimate of 18 months of useful life of Antmier S9. I take it on face value and make a comment: the brownfield opportunities frequently come with electricity already prepaid for some time, typically 6 to 12 months. So your "lower than 99% of the USA" has to be taken with qualifiers: only for multi-year contracts, only for multi-megawatts deployments and only for full construction/renovations. If somebody can live with 1 to 2 years contracts, accept smaller deployments (of the size of supermarket or shopping mall food court) and promise to not make permanent alterations to the facilities; then the electricity price can be zero because it was already paid by the previous contract or the bond issue financing.

Harmonics don't really effect ASIC and solid state systems. For example, the only concern you need to have with harmonics and vibration is with spinning disks (magnetic disks) in a traditional DC environment. Bitcoin miners have none of these problems. As for the rest of it, I won't even bother addressing as Helmholtz resonance is completely irrelevant to anything really... No part of the HVAC system has empty cavities, the hot isle exhaust most of the air out of the facility except for what we wish to recirculate over winter..
There is also plenty of space in the hot and cold isles to handle the volume of air that is passing. We're not using high pressure 36'' (3ft by 3ft) ducts, these are 6ft by 14ft ducts...
The design of the PSU to be above the miner is actually imperative, as bitmain supplies such short DC supply cords. The entire weight of the PSU is supported by two rails that the PSU slides into, and the PSU itself is simply screwed into the front to allow someone to unplug / re-plug the power cord if they need to simply power cycle a miner without having to go into the hot isle...
"The corrugated cardboard + plastic foam + particle board can direct the air around metal warehouse" - yeah and cardboard and plastic have one thing in common, they are both combustible. Regardless if I were stupid enough to do it this way and risk burning thousands of dollars worth of equipment to a crisp, the firecode does not allow me to, nor does the facility itself, so both 'cheap' solutions are irrelevant. If you want to look at what happens when people do this, lookup spoondoolies-tech fire hong kong.
As for multi crew... you obviously are not a very organized person... All S9's we know the hashrate, operation, and the location of every miner in the facility... We keep a database online (intranet) that shows when an S9 goes down, or is hashing slower. A single user can walk to the floor, find the miner, and take it back to the NOC for servicing, often times about a 10 minute operation to swap bad parts and RMA.
As for deployment, yeah, we bring in a team of temps that we pay about 10 dollars an hour to 'install' cable' and do basic stuff. The core team supervises, does final install, and logs the position of the equipment with a tablet on wifi (temporary wifi) pressing the broadcast button one rack at a time. Takes a little while, but once mapped, 1 person working 20 hours a week @ the facility can service 2500 S9 units easily. Its called being organized...
To give you some numbers, the total cost of the solution, compared to the cost of the miners / equipment purchased was 2%. Meaning, 2% of our total cost that we spent on the entire deployment FOR JUST THE MINERS, was the cost of the shelves... The shipping cost was approximately 8% of the total order...
Estimated lifetime for 16nm equipment I give 18 months, before 10nm readily available. With our cost of power 99% lower than the rest of the US, if we're not profitable, then no miners are going to be. at 2.5c per KW, there are only a few places in the world that are cheaper, and nothing else in the US. Technically our old spoondoolies tech miners are still profitable on our current rates, but it would be a waste of space for us to keep them.
Final thought, these things take 5 minutes to install, work flawlessly, and will accommodate future generations of bit-main miners. They work with the S1,S3,S5,S7, and S9... My guess is, they'll work with the S11 as well... How much time labor and money do you spend trying to get the combustible cardboard and plastic up? I've done it before in a cheap facility and its a lot more work than you think.
Obviously you'll go with the combustible datacenter in a chicken coop option, but some of us prefer making money hand over fist and being cheap doing it and not have to worry about 30% of our equipment failing in the first year... I feel many other people are in the same position we are when dealing with multi-million dollar deployments of bitcoin miners. For about a total cost of ownership of 2% greater than fire...

You are 100% correct saying that I've never managed a coin mining operation. I have completely different background. In particular I'm not a mechanical engineer, but I have worked with them. I also don't normally do "operations," but in my company there's a team that specializes in acquiring bankrupt data processing operations, so I've seen quite a few and helped restart them under new management.
I didn't made myself clear in my previous posts. I don't consider your design over-engineering, it is something akin to mis-engineering or show-off-engineering. It is for designed for "lookists" and quick sales, not for the cost-effective operations.
From the mechanical point of view, you've only partially addressed the air flow and the MTTR issue. Your design seems to put the whole weight of the power supplies on the edge of the sheet metal. The better design would be to place the weight of the inside devices on a sort of ledge that is at least 1cm wide and lined with soft rubber. (Sorry, I'm not an ME, I lack proper vocabulary.) Basically your design seriously ignores the vibration and resonances caused by the high speed air flow. The resonances are particularly important when nearly the whole facility will be filled out with exactly identical equipment. Your design also wastes a lot of sheet metal for the bottom of the case (and maybe sides).
The Bitmain miners are already quite similar to the Helmholtz resonator (https://en.wikipedia.org/wiki/Helmholtz_resonance). The multi-mega-watts facility will be like a mad-scientist punk-rock one-note-organ or maybe one-note-straight-flute ensamble. People already are complaining that they are loud, the vibration of the whole facility will badly affect it mechanically.
The other MTTR issue is with the facility shown in the photo. The very long aisles, over 20 racks long, may look impressive on the photo. They are very detrimental to proper operations: it requires multi-person crews for maintenance. If people working alone are forced to work in it they will either skip important work steps or will spend more time walking around than productively working.
I've seen what an experienced water-damage contractor could improvise in hours to direct dry-air flow around the equipment to baffle and cool it. The corrugated cardboard + plastic foam + particle board can direct the air around metal warehouse shelving no worse than dedicated metal racks and cases. It doesn't look good, but operates well, is much cheaper and has no lead time for ordering. I wouldn't advocate that for permanent facility, but what is going to be the expected operational lifetime of the particular models of coin miners?

Can you let me know shipping cost estimate for the smallest bulk order delivered to NY city area PM me if you need more specific details I think I'd like to get a group buy started on these
LMAO - you have obviously never managed a large scale mining operation, this mine when fully upgraded will house several thousand S9's. Now, to put that in perspective, the heat load and CFM requirements are massive. I can stick a bunch of S9's on a shelf, but the blow back from the hot isle due to positive pressure is a nightmare.
Remember, every open penetration that does not flow through equipment means additional strain on the CFM capacity from your system. It also represents a loss of temperature delta between the cold isle and hot isle. Having lets say, several cubic inches of open space does not seem like much until you multiple that by a thousand. You are now talking about just having 10 cabs completely open wasting conditioned cold air to hot air.
In addition, the S9's do not screw in to the shelf, they sit on it. The only thing screwed in is the PSU so you can easily reboot the system from the cold isle... 95% of the time its not the PSU we have an issue with. We have ~ a 70 degree cold isle supply with a 100+ hot isle exhaust and a 30 degree delta. If you aren't an engineer, and have never worked in a pressurized / or data-center environment you have no idea what you are talking about, this isn't over engineering, its engineering to actually make the system work.

I would love 1 or two of these but I am in the UK and by the time I have had them delivered here it we are talking about 200$ delivery costs,
I would ask for a copy of the plans so I could ask about in the UK about having some made up for me but I am sure I would be pissing in the wind.
Kind regards
Alex

Those are nice. Some one let me know about the group buy.
Id be willing to organize a group buy if I get some interest from the community I have the ability to revive palet deliveries as work and break down and re ship individual units I wouldn't know shipping costs until I had them in hand but I would do it to help get these in the hands of fellow community members interested in small quantity units.
Very nice looking setup - I've seen your GPU miner setups, and I have to say you guys do nice clean builds. My only issue with this one (and your GPU one as well) is on the power side, but simply because I don't use the Bitmain PSU's and my GPU rigs don't use consumer PSU's - I pretty much just use DSP-2000BB's. Of course, you have to design to something, and there are so many different PSU's, I really can't fault you for your choice. Your prices seem reasonable as well - having built my own large scale rigs for both Bitmain and GPU's, I can say that your price point isn't that far off from just raw costs of what my builds are typically running (primarily built with 8020 and acrylic).
If anyone is serious about getting some and wants someone just to roll by and check things out, I'd be happy to assuming Greymatter is open to it, since I'm also located in Phoenix (which is what their website lists as their location).

Fantastic , any way to do bulk order , but change out PSU spaces ?
just noticed this, do you want any PSU spaces at all? We used bitmain PSU's, mostly because we already have a ton of them and the way they draw air from the cold isle is idea. If your looking for just a shelf to hold the S9 and not the PSU, we could easily do this, it would probably drop the price significant. Maybe just have a bit of a shelf above to support a standard PSU or a standard server PSU? You should PM me exactly what you're thinking, its not that hard to modify.
Its not just Paypal security that's wrong here.
Think of MTTR, Mean Time To Repair/Replace in case of any equipment failure. How many screws need to be untied/tied? Is it possible to replace just a single unit without taking offline the whole shelf?
It seriously like anti-engineering as far as cost of operations.

LMAO - you have obviously never managed a large scale mining operation, this mine when fully upgraded will house several thousand S9's. Now, to put that in perspective, the heat load and CFM requirements are massive. I can stick a bunch of S9's on a shelf, but the blow back from the hot isle due to positive pressure is a nightmare.
Remember, every open penetration that does not flow through equipment means additional strain on the CFM capacity from your system. It also represents a loss of temperature delta between the cold isle and hot isle. Having lets say, several cubic inches of open space does not seem like much until you multiple that by a thousand. You are now talking about just having 10 cabs completely open wasting conditioned cold air to hot air.
In addition, the S9's do not screw in to the shelf, they sit on it. The only thing screwed in is the PSU so you can easily reboot the system from the cold isle... 95% of the time its not the PSU we have an issue with. We have ~ a 70 degree cold isle supply with a 100+ hot isle exhaust and a 30 degree delta. If you aren't an engineer, and have never worked in a pressurized / or data-center environment you have no idea what you are talking about, this isn't over engineering, its engineering to actually make the system work.
OP might want to revise the title of this thread. I assume "Self" should actually be "Shelf"?
Nice looking package, >35 some-odd TH/s per shelf with s9's, what's not to like?
Except the prices... Ouch!
Pretty sure I could have Bud Industries or other enclosure maker do a run for quite a bit less...
Edit: looking again at prices, you show $3,600.00–$5,600.00, I now take it that is pricing for bulk quan and not each?

Yes, they are manufactured in bulk and i don't have the time right now to offer them as single units (im still setting up 3mw worth of S9s). They will come palletized from the manufacturer. broken down the prices are $140-$150 each.
I just dropped a line to my rep at bitmain, if they're willing to list them through their site for us i'll put the time into setting up a packaging / shipping solution and put some staff on it. Until then its bulk or bust
I do not want to give an address and name and contact info. Just to find out shipping a set of 24 to 07731.
you want 3600 for a 24 pack that is 150 each plus shipping
and a 90 day lead time.
So you get to hold my paypal beyond the safe time to put in a claim for no delivery.
I will pass. A 3 to 4 week lead time makes a lot more sense.
But the gear is really good looking I will give you that.

If you are serious i can get a shipping quote from the manufacturer, but i would assume ~$300 to NJ.
Lead time is 4-5 weeks, not sure where you got the 3 months from? I am not holding any stock so, manufacturer takes 1 weeks for material delivery, 1 week for forming, 1 week for powder coating, 1 week for delivery. I like to add an extra week on to the estimate just to be safe.
Ok, so I have bad memory for names and faces, but reasonably good one for acronyms. Check out "NEBS Level 3".
I'm going to give just a Wikipedia link for starters: https://en.wikipedia.org/wiki/Network_Equipment-Building_System .
Please read that and if interested follow the links. You'll find plenty of examples of no-bullshit ways to rack up electronic equipment meant to be operated continuously. I understand that Bitcoin mine is not the same as telecommunication central office. Anyone reasonably intelligent would be able to decide for themselves which of the telco requirements don't apply to coin mine.

FWIW Google Images only came up with that one.
The yellow thing looks like a retractable power cord with an outlet box on the end of it. Nice touch vs having plugs here and there in that aisle.

Yeah, money laundering through terribly overpriced network installations is still the thing. It used to be done mostly by reshipping unused obsolete (or nearly obsolete) Cisco equipment with the original price at the time of the technology introduction. At the low end of price spectrum I remember Cisco color-coded Cat5 (not Cat5e) 1 meter patch cables for approximately $25 each. Nowadays Cisco is actively fighting those dodgy resellers.
They are now transitioning do doing dodgy billing on digital audio-video installations. Some of those examples ultra-neat cabling jobs shown in magazines are in fact not computing installations but A/V installations serving digitized movies locally for residences or production facilities.
I wish I had better memory for people names and faces. But the sales commissions for the people with right connections are awesome, e.g. from 50% to 75% or even 90%.
And lets be honest, the price of the shelf breaks down to 2.5% of the investment of the miners (not including power supplies...)
I'm not trying to begrudge you of your markup. You are free to charge what the market bears. I also understand what were the NRE costs for the ASIC versus NRE effort for your cases. The ultra-neat-freak segment of the custom hardware installation market is such an obvious place for various frauds. Maybe the manufacturers aren't the most interesting, probably the buyers and the salespeople are. Just don't be surprised if some investigative journalist shows up near your production facility.
We engineered the shelves ourselves for this deployment. The last picture is one of eight cold aisle rows that will be loaded with S9s by the time we're done.
I get this is bitcointalk and scammers are rampant but we've been selling GPU cases for going on 3 years now and i wanted to offer these more out of courtesy to the community. Yes, they are a little price but they're made in the USA, are powder coated, and function extremely well.
These should also work for Bitmain's next generation of miners as well since they are pretty set on their form factor now.

Besides, who wouldn't want to put 21 S9s in a rack!?!?!

Fantastic , any way to do bulk order , but change out PSU spaces ?

The bottommost picture, with 20 racks in the perspective view, reminds me of strikingly similar interior photographs from some bankrupt datacenter facility financed with securities fraud. The pictures I've seen were much less uniform with the contents of their racks, meaning that racks were filled with a variety of equipment, but only 1/3 to 1/2 of the each rack was filled. I also remember that yellow circle with the pipe pointing down in the far view. Is this type of the arrangement some industry standard for the datacenter equipment?
I can't recall the company name. Maybe someone here saw it too and could refresh my memory?

We are proud to share with the public our custom Antminer S9,S9j,S9i / S9K,S9SE rackmount enclosure. These 7U/8U shelves are designed to house 3 Antminer bitcoin miners with bitmain AW3++ power supplies. This allows those running in traditional datacenter environments to effectively host Antminers while maintaining hot / cold air containment.
We are currently running a clearance on our in stock quantities! After these sell out we will only be offering quantities of 50+ so get these while you can.
Please place any orders through our site here:
7U shelf for S9,S9j,S9i
7U shelf for S9K,S9SE
These shelves will also work for other bitmain miners such as L3,D3 etc, as well as similar units like dragonmint T1s.
