Title: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on May 26, 2019, 05:59:36 PM Hoping to get one in around a week. We will do a youtube video and setup review.
I will post back here in a bit. Feel free to post. A1041 Corrected to a1041 First video https://www.youtube.com/watch?v=vyQWSx8XL40 second video https://www.youtube.com/watch?v=btdHHbfSJ84 I will do more when I get second unit from buysolars house. Edit third video Your video will be live at: https://youtu.be/jB0nkD7RcqU fourth video https://youtu.be/iZCEtbMz3vw Title: Re: Buysolar and I will getting the A1021 to review and demo. Post by: philipma1957 on May 26, 2019, 05:59:54 PM Spacer. I put all questions and posts here in the spacer post.
Is that a new model? I thought it was A1041 for the latest Avalon Philipma1957, I'm not a miner and I usually don't frequent this section but I know you have a solar mining operation that's already paid for itself (if I recall correctly from reading a post from a while back). I think that's awesome, and I'd like to see the video you plan to make and any others you've made. Can you give me a link to your youtube channel? I have a thread on first array.I think solar power is the key to the energy consumption problem of crypto, and I'd like to start getting into solar in general if I can ever save up enough money to buy property. I'm still on the fence about that. Thanks, bro. Fully paid off. I have a thread on second which is still a work in progress. I will put links in later. I have a real interest in the Canaan a1041. Solar is a 20-30 year product. Once your array is paid off your power cost is next to nothing. We got lucky and caught the 2017 run up well. Paid off the first array. So the a1041 has a good value if it is durable. As it will always earn profits. Due to the array being paid off. We are looking for dense like 30th or 40 th or 50 th. But reliable is just as important. We have a few Avalon’s in the new array. They have run perfectly since December . That is a real value to us. Do we know whether the pricing on the blokforge and Canaan websites are accurate for when these are available to the public? Very cool. :) I've been in talks with Canaan as well, but I haven't heard any news recently. Here are links on solar build 1, build 2 Buysolar and I have been mining together since 2014 He built a solar array back in 2016 https://bitcointalk.org/index.php?topic=1369207.0 build 2 work in progress- ie demand creation using mining gear to allow for a large size array https://bitcointalk.org/index.php?topic=5099194.0 youtube : note all done in a raw style no edits not slick which is an intentional decision on my part https://www.youtube.com/channel/UC-K1Sokgy3-4CdV_uZF8ubw/videos?shelf_id=1&view=0&sort=dd This show more then one avalon in more then one test. Also show a lot of other gear. Which does need to be shown. Many miners are of the following belief system "I love blank and fuck everyone and everything else". I am an inclusive miner. I Mine many coins with various gear. Our new location has a lot of different models of: btc asics ltc asics gpu I can honestly say avalon gear has always had a better reliability factor for me than other gear. Since my new solar build is a 120 mile round trip with tolls I need reliable gear. Going up to fix 1 s9 is not worth doing. I have about 600th of gear mining and losing 14th of hash is not worth the trip. So we are playing the game of lets wait for more s9's to break to make the trip worth it. I like to wait to 10% of the hash rate is down before I ride up to fix it. So I am doing 1 trip a month to fix dead gear. losing around 30th of hash each month or 280 usd a month of which ½ is mine ½ is the hosting warehouse. 280 x 12 = 3370 a year. I am hoping the A1041 stops this issue. Since my power cost is always ½ the coins the A1041 can be a little less efficient if it is a lot more reliable. Phil will this unit be rasp pi free? @ yankees. They emailed me for my address today and mentioned to me that they would want to send the no rasp pi units. So I am hoping to see a unit that connects directly to the internet. @ yankees. This would simplify deployment and maintenance, curious they took so long to make this decision, its literally just bolt a raspi on each unit...They emailed me for my address today and mentioned to me that they would want to send the no rasp pi units. So I am hoping to see a unit that connects directly to the internet. Can't wait for the review. This would simplify deployment and maintenance, curious they took so long to make this decision, its literally just bolt a raspi on each unit... Yeah I need more reliable gear that is power dense/hash dense.Can't wait for the review. if these units do 32th and don't drop out much it would help us a lot. we may do a third build which will be a 160 mile round trip and bigger then the Clifton build. Clifton is upgrading to 120-130kwatts from 65 -70 kwatts. This not happening I can't afford 5% down in a month as that is 7.5 x 33 = 247th. Nice can't wait to see the internal controller units. Those are the ones I've been waiting to see launch, it's a bonus not having to worry about a Pi or any of the converters is a plus. It's listed in the specs but can you confirm if it's a built-in PSU model or not? Psu should also be built in. I am really excited about the eth daisy chain of these units. I have no idea if they can do 254 but if they can do 40 well it is good enough . With our Warren super build cancelled> We lost bid for the 140 acre property. Warehouse owner and partner with buysolar and I Have switched and are going to plan 'b' We will expand power at the current set of warehouses from: 65k-watt to 175 k-watt build out. Then expand again from 175k-watt to 475k-watt. Solar will cover the first 90kwatts. the rest will be at 5 cents. The expansion from 65kwatt to 175kwatt is done on the power side. We have 23kwatts of gear to put in now. So by next monday will will have 88kwatts running and 87kwatts to fill. These new avalons figure heavy for us. they are pretty dense at 36.9th and we won't need anymore switches if the eth daisy chaining works. Are they the most efficient gear no they are not. But no switches needed saves $$$ Short cheap eth cables saves mess and $$$ If they are as reliable as the A921 or the A721's the 130 mile round trip to fix gear will be reduced greatly. We were up in Clifton last thursday cleaning all gear with an air hose. After 8 hours we did ⅔ of the gear and have ⅓ to clean. The l3+ units still need to be cleaned 25 of them. We did 25-30 s-9's we did 8 m-10's we did 1 s-17 we did 1 s-15 we did 1 t-15 we did 1 l-3+ we did 1 t2t24th all of the above stone cold dusty nasty dirty and all of the above slow to clean we also cleaned our avalon gear 1 a921 2 a721 all three noticeably cleaner inside due to fin designs. all three faster to clean we have had about 7 months of mining in Clifton and the 3 avalons never dropped out or stopped mining every other company's gear dropped out at least once. for us that could mean a six week time between maintenance trips to Clifton not 3 week trips. so 8 or 9 rides to Clifton vs 17 or 18 rides to Clifton Two Guys me and buysolar to do the maintenance . this is a big savings for us. maybe 130 x 10 = 1300 miles 6 x 10 = 60 in tolls 16 x 10 = 160 work hours 2 or 3 switches lots of eth wire at 2/3 foot vs 10 foot. 1 router could do 10,000 units with only two 24 port switches 218 units per port 218 x 23 = 5014 units per 24 port switch. ;D Realistically for us if we go all avalon on the next 87kwatts we get 35 units do 7 per port use 5 ports. it works fine. Avalons are a beast when it comes to reliability, I've never had a real issue with one. It's been a shame they haven't been able to come out ahead of everyone else on an efficiency launch. I think it's been a huge step getting rid of the external controller then following up with the Eth daisy chaining keeps them unique and easy to network. All the benefits without the potential points of failure. I wonder if these will still be able to operate as 1 worker for all linked chains or if they will now be individual workers. It didn't even dawn on me the switch savings, I'm lucky enough that I'm still small and can get away with a couple home routers networked together to meet my needs and boost the home wifi network. I am so jealous about guys with solar setups. I can't do it for a few reasons: 1. HOA 2. Even if #1 is negated (although I don't know yet how), I would need to install a new roof first, but the old roof has no problems, so i would have to pay 100% for replacement. 3. See point #1 Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 24, 2019, 09:12:19 PM We got tracking for these today. May show by Friday the 28th of June.
A lot has happened Since I started this thread BTC is over 10.5k! It was 8.7k when this thread started. from canaan website Specs are: Model Name AvalonMiner 1041 Standard Mode 31TH/s，-5%~+5% 1736W，-5%~+15% @ 20°C, 220V AC, Wall-Plug Turbo Mode 36.9TH/s，-5%~+5% 2361W，-5%~+5% @ 20°C, 220V AC, Wall-Plug Power Supply Specs 2450W output, 93% Efficiency, 185~264V AC 50~60Hz Chips 240 x Canaan A3205 Third Gen 16nm ASIC Connection RJ45, Up to 254 Miners(theory) Daisy-Chain Connection(IPv4) Cubic Feet Per Minute 250CFM Ambient Temperature -5℃~35℃ (Standard Mode) -5℃~30℃ (Turbo Mode) Air-intake Temperature -5℃~35℃ (Standard Mode) -5℃~30℃ (Turbo Mode) Operation Humidity 5%~95% Non-Condensing Cooling 2 x 12038 FAN Noise 70db Net Dimensions 190mm x 190mm x 292mm Net Weight 7.9kg order link below https://canaan.io/product/avalonminer-1041-august/ I blue bolded the most interesting feature of the new gear. No one else does this. If the eth cable linking works well this will be a knock out product. The savings on switches for a 50 rig setup. Shorter eth cable runs. Buysolar and I will each get one of these units We will run them apart. We will then link them via eth cable. Assuming it works as expected we will order at least 10 of them. I want to thank Steve and Lily for sending demos. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 24, 2019, 10:03:30 PM Psu should also be built in.

Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 25, 2019, 12:17:40 AM I was always able to use one 24 port switch
But the clifton build changed my world of mining. we are using 70 units two 24 port switches one 48 port switch three routers modem to one with 192.168.1.1 for all non-mining gear to two mining routers one with 192.168.0.1 for all sha gear uses 24 port and 48 port about 40 pieces one with 192.168.10.1 for the L3+ uses 24 port about 22 pieces the setup above could do say 240 + 250 + 250 = 740 miners you would many many many switches I guess 30+ 24 port or 15 plus 48 port. but if we push avalon we could do 1000's of them with no extra switches. realistically add the 87kwatts use 35-40 avalon then if we do 400 more use 150 avalon not a single extra switch. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 28, 2019, 04:12:01 PM Okay the miner arrived but not the psu. Disappointed mostly seems to be fault of DHL gear was due thur.
it is fri. 2 boxes one for miner came today box with psu is floating about buysolar is getting a set of 2 boxes like I am in his case neither box has arrived here is youtube video of opening of miner box Your video will be live at: https://youtu.be/vyQWSx8XL40 Published you can see it full size image https://i.imgur.com/nAOQnDA.png https://i.imgur.com/UF41slb.png (https://i.imgur.com/UF41slb.png) Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 28, 2019, 08:51:31 PM It has arrived. Unlike the other review I have been given a stand alone psu with cables. What does this mean it means I had to take off the controller case to see the buss bars as they are not marked pos or neg.
The psu did show pos and neg so I was able to correctly wire the gear. A relief for sure. It is not that loud it can be sound proofed with the psu I was given from them. I have it set to normal and I am around 29th and 2060 watts. That is better then the m10 not as good as the m20s. from whatsminer. It is pretty well made I will need to give in my case examples vs pass the popcorns So a quick little review of the A1041... Front: https://i.imgur.com/V4W4zaL.jpg PSU Side: https://i.imgur.com/YSzMS6H.jpg note the clean built in psu with buss barr attached on passthepopcorn's gear. and the loose psu hook up https://i.imgur.com/hXUohrU.jpg (https://i.imgur.com/hXUohrU.jpg) worse then that is the miner buss barr screws are not marked https://i.imgur.com/J1VbJFZ.jpg (https://i.imgur.com/J1VbJFZ.jpg) I removed the controller lid and could see the - + markings. thus hook up was okay close to 29th at the pool. and 2050 watts that is 2050/29th on low speed 70.6 watts a th my m10s would do 2250/31th on high speed 72.5 watts a th https://i.imgur.com/vDUk3RA.png (https://i.imgur.com/vDUk3RA.png) Title: Re: Buysolar and I will getting the A1041 to review and demo.

https://i.imgur.com/pCg5tSM.jpg (https://i.imgur.com/pCg5tSM.jpg) watts at 2061 https://i.imgur.com/dxVnsSa.jpg (https://i.imgur.com/dxVnsSa.jpg) we will not be fully solar here this site has 5/6 cent power deal. as of now we plan 90kwatts of solar 85kwatts of paid power. cost say 3-3.5 cents net for 175 kwatts this is 126000 monthly kwatts at 3.5 = 4410 USD a month bill we could add 300kwatts more of 5/6 cent power but that is for 2020 or dec 2019 she seemed to settle in at 31.5 th and 2055 watts or 65.8 watts a th. so if we were all avalon a1041 we would have 83 of them doing 31.5 th or 2.61 ph earning 2.5 coins a month which is why gear is selling like water in a desert. we have gear and do not have the room for 83 of these but depending on the next set of tests, which will be the ethernet cord daisy chaining. We are looking at getting 10 of them. My assumption is the we all go to built in psu with buss bars. and not the loose style I am testing today. I also assume more pools and more features in the GUI. As mine is exactly the same as passthepopcorn. next test is high speed so far it pulls 2650 vs 2050 watts it hashes at 36.9 vs 31.0 th so 71.8 watts a th I will let it settle more. normal 2050 watts 30.8-31.0 th this was about 1 hour 20 minute test. 66.12 watts a th turbo 2640 watts 34.9-37.1 th about 1 hour and change 71.16 watts a th So beta psu and beta software it looks good but not great Still with todays prices this gear is a moneymaker. biggest quirk was it did not run well on mmpool.org a small btc mining pool. What is it worth? good question Hard to tell with the beta psu I would not rush to buy it. I do assume Steve of canaan will post on the psu as I prefer the attached style over this loose beta model.

Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 29, 2019, 12:25:34 AM I thought they were supposed to be 1736W @ 31TH? maybe they are maybe not as the psu I have could simply be a 88% psu. I am posting a video in a minute you can see this is clearly in beta status. Your video will be live at: https://youtu.be/btdHHbfSJ84 the above will take time maybe 10 more minutes to load. this demo does not have the same psu setup as passthepopcorn's unit had. I have multiple meters and will clock this gear very closely. the rooms temp is 30c or 86f the rating of 1736 watts is for 20c or 68f Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: Biffa on June 29, 2019, 12:29:46 AM Thanks for keeping us up to date Phil, as you said there isn't much hardware around at the moment.
Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 29, 2019, 12:42:17 AM Lets say
once fully tweaked it is 60 watts a th for the 31th setting not 56 and it is 68 watts a th for the 37.2 setting not 65th. at current prices it is viable gear. it does not need many switches if it allows 100 or more for a daisy chain. It Steve said to me he could send me ten this weekend I would take them with the loose sloppy psu setup and wait on the buss bar psu's Avalon is reliable gear for me so far. eth daisy chaining seems like a good idea. I will drive to buysolars house and bring his to my house and setup a 2 unit daisy chain. Should video it on sat. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: Biffa on June 29, 2019, 01:52:16 AM Even with these its getting harder.
Blokforge has upped the price of the August batch to $2300, September sold out, so October is the earliest at reasonable prices. Canaan has some September left, but August all sold out. As I'm not shipping to the US I'd probably choose to get them from Canaan direct. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on June 29, 2019, 01:53:37 PM Ran it over night does about 11 amps or 11 x 230 = 2530-2600 watts and about 37.05 th so 37.05/2530 = 68.29 watts to 70.17 watts on high speed.
Second unit was picked up from buysolar. I have both running at normal speed they do around 30-31 th at 2016-2015 watts so 61 th at 4031 watts on normal speed. both have loose style psu. and basic demo/beta gui. eth daisy chain does not seem to work, but I will fuck with it some more. so I have 2 ports 2 ip's at the moment. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on July 02, 2019, 04:30:13 PM Found out how to hook up daisy chain
So I thought there was a problem with it being on DHCP but after setting up another one and changing the pool it seems to be fine on DHCP. When I switched the previous ones to static all I changed from what the miner picked was the DNS, to google's. The miner itself picked up an IP from the firewall and the gateway / subnet settings. One thing that was different from yesterday was when I ping the provided DNS today I get a reply, yesterday I didn't. okay looks like I got a daisy chain working. so 1 port is used but 2 ip's 192.168.1.120 192.168.1.107 so this will cut switches down but you still need 2 addresses. that is good and bad. the good is you can check each unit and know if it is working this is nice if 1 of 20 units goes bad you know right away what is wrong. the bad is a router has 1-254 addresses so a really big miner will need to do some sub nets.. For me in Clifton I have 3 routers 192.168.1.1-254 comes off modem and does zero mining it goes to a 5 port switch that goes to 2 routers 192.168.0.1-254 this is all sha-256 45 pieces of gear 192.168.10.1-254 this is all L3+ 25 pieces of gear. I could buy a router with 192.168.2.1-254 then run all avalon sha-256 get a router with 4 outports 1 port for a controller laptop and 3 ports with daisy chains of a1041. easy to check and monitor the mining routers can be fairly low-cost. https://i.imgur.com/yRIerA7.png (https://i.imgur.com/yRIerA7.png) Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: Trinislacker on July 02, 2019, 05:02:08 PM Honestly though Phil, saying that the 254 address limit is bad is pretty nit picking, it’s a limitation with IP addressing and not the miner. The IP range limits are present in most miners outside of canaans due to their independent controllers . I think daisy chains are a brilliant idea that would help reduce clutter and cost, it would be even better if it had ring type topology to help with redundancy, can you test this Phil? Meaning the second miner goes back to the router and if any one cable is unplugged the miners still are connected.
doesn’t IP address ranges end at 255? :P Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: PassThePopcorn on July 02, 2019, 05:28:25 PM 255 is typically reserved for broadcast and 1 is usually for a gateway depending on your setup. The range is 1-254. To your question on the daisy chain I believe this answers it
Yeah you will need IP's available it appears the miner simply acts as a pass-through and the miner still needs to connect to your router/firewall. Good news is you can access each one individually. I believe if one of the early ones in the chain goes down you loose all the rest I'll test that when I get back. - This occurs if one machine goes down (so far if the PSU is off or dies) the rest of the miners in the chain stop, from the power reading they still pull full power. With the broken A10 however (where the hashboards don't work, I don't think this has a controller problem) the daisy chained miners still work. @Phil instead of getting a router and setting it like that what about a pfsense box, operates as a router. While I wouldn't suggest it, on your current one you should be able to change the subnet from 24 to 16 and increase your available IP's. It depends on your setup but if you can change it to 16 you would be able to run machines on 192.168.x.x instead of 192.168.10.x. Most big mines can run tens of thousands of machines off one firewall, they don't typically go to a /16 but a /24 with a change in octet 3 for groups of units. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on July 02, 2019, 07:49:15 PM I am just getting bigger now. I know about subnets but in a classroom 10-15 years ago.
Real world 150 miners is most I have done in one spot. the modem is verizon the router is verizon. belong to the warehouse owner. so a 5 port switch to my 2 routers was cheap enough and my 2 routers were also cheap. my third router will also be cheap. so being isolated from the owners gear still gives me an easy 750 miners which is not happening. I do have to say have a different ip for the avalons in my case is good and not an issue. It is pretty much good and allows easy access teach one. up to 250 or 254 then things get more complex. So is bad the right word maybe not . That ring idea is good I will check it later. Title: Re: Buysolar and I will getting the A1041 to review and demo. Post by: philipma1957 on July 04, 2019, 05:40:30 PM Ring idea makes a loop and crashes the net completely.
This has happened to me when I do a lot of eth switch work and make a mistake causing a loop on a switch. So for now the loop idea is out. I want 10 of these as soon as I can get the ten. If I get that many I will do extensive tests of eth cables. Chain of all cat 5 Chain of all cat 5e Chain of all cat 6 Chain of all cat 7 I will measure hashrate on all 10 units with each set of ten cables As we all know most of the time cat 5 or cat 5e are fine. But with ten cables linking cat 6 or cat 7 may be better. It will be interesting to see if A. Gear is stable in a ten unit setup. B. Gear hashes lower with cat 5 C. Gear hash descends as link grows. D. Gear hash is improved with cat 7. Ten unit test should be enough to help people decide if they want the gear. And how long to try to make the chains.

I will have to look for one soon. Since I want to do extensive testing of the a1041. A ring setup with 50 units may be really good. Buysolar and I want to cut a deal for a goodly amount of these units. While I am here do you have a smart switch in mind that can handle a ring setup? Edit Thanks for pointing this out I did some googling I think Cisco me-c3750-24te-m 3750. Can do what you say. I was on Cisco website and they say they can do it. If so then the tech offered by Avalon is even better then I had hoped. Huge networks can be done far easier then any other miner I know of.

Chain of all cat 5 Chain of all cat 5e Chain of all cat 6 Chain of all cat 7 I will measure hashrate on all 10 units with each set of ten cables As we all know most of the time cat 5 or cat 5e are fine. 1gpbs ethernet mandates the use of 5e. Testing 5 is pointless at this point in time, no one should be buying those anymore. If the miner only does 100mbps 5 vs 5e the 5e will let less errors in (translates in slightly faster speeds). Similar to... Using cat 6 for 1gbps. Its not really needed, but its better. For 10gbps it can work in short lengths only (50m vs 100m). 10gbps should be done by cat 6a or cat 7. I don't think you are going to find any miners with 10gbps lan ports, but it might be available for cascading switches and such. And since you enjoy the fun, there are also cat 8 patch cords... In short: cat5 100mhz cat6 250mhz cat6a 500mhz cat7 1000mhz cat8 2000mhz If you ask me, 5e or 6 at most is what any mining operation (and most LANs) would ever need. I did not want to confuse you, but you can actually use anything from 1 bit to 32, not necessarily just 8, 16 or 24. You could use, 12, or 20 bits. Just remember there is always a network address and a broadcast address, any remaining IPs in the middle are the IPs you can use. Use this calculator (https://www.calculator.net/ip-subnet-calculator.html) and see the endless possibilities. Private nets (https://en.wikipedia.org/wiki/Private_network) are up to 24 bit (10.0.0.0/8) Most switches are layer2, they don't care about this except the very smart ones that can to layer3, and those, of course, can do the whole 32 bits. Limiting yourself to 8 bits is nonsense. Maybe that was more critical when people used 10mbps hubs instead of switches, but that's long gone in the past. Unless you have real cheapo gear... (TP-Link? :)) Computer with pfsense is good too! There are also many embedded devices with multiple ports, such as pc engines (https://www.pcengines.ch/) you can install any decent os yourself for routing, firewall, etc. Title: Re: Buysolar and I will getting the A1041 to review and demo.

I did order 2x 48 port switches from newegg they are cisco and should work well. they are the ones I found via google. The new network will be verizon modem to router to 3x 48 port switches to miners in 3 groups the route will also handle the warehouse owners net traffic it has 1 gb wan in 8 ports out and 3 bands of wireless. he will have under 7 pieces of gear on the network. we should have about 85 pieces of gear setup with more to come. even if we max out available power we will be near 170 pieces of gear. So we should be good to go. very soon on our end. but we will only have 2 a1041's in the short term. |
