LOL

I know

CK created a new thread and called it Switch discussion because I posted some pics in Slush's pool discussion forum.

Not really a discussion on switches.  Switches were barely mentioned.

cris, made comments about "switches" and everything got out of hand.  This topic should probably be deleted because it is not a proper discussion on switches.

This thread.... I don't even...    wow.   

Will do.




Actually, I have 16 not 12.



If you noticed the additional equipment I said I'm waiting to get here from Amazon, you will understand why I'm waiting to make everything neat and zip tied; you know the drill.



I will get Cat 6 soon enough.  All of this Cat 5 was accumulated from my cable install days before I started training telephone technicians.


Yes, I will make things neat after I install PDU's.  I made an earlier post about 25 minutes ago showing the PDU's I ordered.  I will have to take out some shelves and re-install them in order to get these long slender PDU's behind them.



Agreed.  I just KNEW I was not finished yet.  I wanted to bump everything up from 120V to 240V with PDU's



Actually, you will get DOUBLE the power (wattage) if you go with PDU's plugged into 240V rather than plugging in straight to 120V circuits.



Sorry, not right now.  I don't know that I will ever team up with anyone unless they have a LOT of capital.  For now, I spend my time at home these days taking care of my little boy.  I will be home schooling him soon.  He will be 4 years old in January.

The reason the attenuation gets higher is because of the CAPACITANCE in the cable.  A capacitor has to be at least two metal plates separated by an insulator.  Of course, Cat 5 or 6 is multiple metal plates separated by insulators.  It has capacitance in it [the cable].  The more length we have, the more capacitance we have.  The more capacitance, the higher the attenuation.

 and good for no wifi

Sorry this is alot to read.  Just trying to help everyone get a better understanding and so u can get better speeds and results.

I like ur setup.  I wish I could get my hands on that many S3s.. or more than I got atleast .


The racks do help beautifully.  Thought.  I will say that cluster of Cables you have.  Can reduce packets.   Due to cables overlapping  and crossing over eachother(crosstalk)      Id try and neaten that up.   If you've got them all plugged into ur switch and than another cable to go to ur router.  Umay get better speeds and performance if run Cat 6 to ur switch (Cat 5e is limited for speed) (Id recomend STP)  but run it to  a patch panel  and than run that to your router.  


Because as it is..  theres always 50 devices or in u case 12 devices conencting with 12 cables..  than all forced to go through 1 cable to get to ur router.  

So maybe u could hide the switch... Run the cables around the trim of ur house(but watch ur bend radius)     The neater ur cables are the better the results.  




A suggestion to you though.  Remove all your Cat 5e cables... Why.. because the TPlink switch has potentional to incorporate a higher speed and latency.  So running Cat 5e is limiting speeds and performance and increasing cross talk no matter the switch.   Switches only do so much depending on your cabling.



Id spend the extra $5.00 for Cat 6 (All my miners are Either Cat 6 or Cat6a).


But if you neaten up those wires.  Space them out from eachother...  make make it look neater.  and also move your switch so its not ontop of the miners or anything.. This will increase heat and majorly increase the noise in the network.













not bad not bad not bad not bad.      Pretty good If i do say so myself.  





Again though.   I would think of cleaning up the cabling and moving the switch(Itll help increase your results dramastically)


I thought it would bea  good idea to buy a 1200+w PSU(in time)  and connect 2 miners per PSu instead of 1 miner for every PSU I have.    1 550w 1 600w all the rest are 750w which run at like 45%-50% load.... barely


... Want to team up in mining?  Legit.

I will go cat 6 as soon as I get other equipment here.  A lot of my equipment will be here Friday.  The S4 I ordered is "...awaiting clearing agency review. / The package is at the clearing agency awaiting final release" according to UPS Tracking.



I just ordered some new equipment from Amazon:

I ordered two (2) of these PDU's from Amazon.  I wanted to keep the cost down.  So, I did not order any with monitoring capabilities. 

http://www.amazon.com/gp/product/B0012VN0I0/ref=od_aui_detailpages00?ie=UTF8&psc=1



I ordered 24 of these 6 feet cords.  I just showed you one color I ordered .  I ordered green, yellow, red, white and black as well.  So, six colors and 4 of each color for a total of 24 cords.

http://www.amazon.com/gp/product/B00B2BTQCO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1



This is the outlet I ordered.  Three of them for now.  $14.90 each

http://www.amazon.com/gp/product/B00002NAT9/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1





The shopping list is actually longer than this.  Not enough room on the page for you to see it all.


David

I do not hash WIFI.  You see a little bit of that switch I posted on the top shelf and cat 5e cords; no WIFI

==============================================================================================





Lol ima PC Guy but its all mostly the same.       ITs all intertwined with the same category.

And yes I did indeed see that.   I skimmed over it.   Its a pretty good Switch.



Now.  If you wanna really make progress. Ignore Cat 5 and Cat 5e and go for Cat6 /6a  this will help maximize your performance for your miners and your switch.. also help reduce and crosstalk/Noise and hopefully limit some collisions.


If ur a big spender.  If ur like my.  I rather spend a ton on my network setup than go half ass on it... Im not one of those people where.\


Oh it works.. its good enough.  When its networking...  Its gotta be the best of the best.




If ur a big spender.  Go  Cat 6a STP (Shielded Twisted Pair)   So ur Crosstalk will be Cut in half,  noise will be cut in half and speed/performance will be maximized.




Hey.  If you aint going to do it right.. dont bother..  The slopppier and the cheaper you are.  Your just asking for more problems down the road.




Though this is what I'd do.


Just some Ideas to help you maximize your performance..








remember the Faster ur hash speed... the less HWe,  the cooler r miners,  and the less distance(attenuation) for your data to travel..The better the results you get.


(Try not exceed 95M in cable distance,  attenuation will occur if you go over 100m with the wrong network setup and cables)



wow i love explaining this.  




I've always wanted to team up with some people and well.  At this point.  Create our own giant Bitcoin farm.   With 2-4 employees.   3 Miners get together and we all work something out and we all combine our hash power,  setup our own network for our miners and mine away all on one pool with all the hash power we got.

Not trying to tell you anything UNLESS you were not familiar with a MAC and only fiddled with PC.

By the way, the switch specifications I showed you also had 100 BASE T and 1000 BASE T on 5, 5e cable.  Not sure if you saw that in the specifications I listed or not.  I went back to edit it and made them red as well.

May I ask.. What your trying to tell me?  I dont get it.    Your trying to tell me things that I know more about.  

Networking is my specialty.   read my posts and itll all make more sense.    






PS.  Dont hash on WIFI.   If u got a 5GH/z line or a good antenna. Go for it..  but if not.. dont bother.  I mean 1-2 miners is okay.  But the Radio Freq signals collide with eachother in the air which can majorly decrease ur performance....Though u would not notice it.. it is there.    Not saying wifi hashing is bad.     It's just insecure and less consistent

Connecting to a MAC or any other devices connected to your Airport Extreme Base Station:

https://www.youtube.com/watch?v=gpeRdji4BmM

YEA TP link is always one of the better brands to go with.. They handle higher speeds and are more redundant.    It still will never factor out collision domains.

This is way.  If u were to Grab a switch right now.  and connect 10 devices to that switch and than to ur router.  and than hve all 10 computer ping ur router at the EXACT same time.  U willl have 1 or 2 maybe more computer have a Time out.  This is due to Packets colliding with one another.


Think if it this way.   you have 2 cars  each facing eachother driving straight head on at eachother at maximum speed.......The cars wont go through eachother.. They will collide... Or they will both stop and allow one car to go forward a few seconds before or after the other car.



It's the same with collsion domains 2 computer on 1 switch = 2 cars drving had on at eachother.. if they collide.. they will stop and reset and one packet will send a few seconds earlier than the other packet to stop a collision from happening..  This is a collision domain.


It's deffinately  plus to have much better switches but sometimes having the maximum amount of ports is a bad thing...    No matter the specs it has.




Think of it like this.   u have a 4 lane road that cant fit anymore than 4 lanes total. and u try to squeeze in 10 lanes....  or u try to throw 10+ cars on that 4 lane road... Things will slow down but they will still work.




 Damn.  I can surely say im learning alot.. Damn

The trick is also.. Use a slow wiring or say 10BaseT for connections to ur switch.   than from ur switch to say another switch go for 100BaseT  and than Switch to router try and get 1000Base.  Why... Well.   

Think of that part like speed limits.   u hit zone were its a max speed of 10mp/h or w.e  everything gets slow and cars all get real close to eachother.

Than after driving for 5 minutes ur now ina  50 zone..   so now everyone takes up  leaving nice big gaps inbetween each car. 


Now u just hit a 100 zone and now the gaps are really big increasing the amount of packets or Cars that you can hold.









I hope this helps

SOME specs on my Apple Airport Extreme Base Station (ROUTER):

Interoperable with 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac-enabled Mac computers, iOS devices, Apple TV, Windows-based PCs, and other Wi-Fi devices
NAT, DHCP, PPPoE, VPN Passthrough (IPSec, PPTP, and L2TP), DNS Proxy, IPv6 (6to4 and manual tunnels)

All of my miners are setup via DHCP through my Apple Airport Extreme Base Station; not static IP.  I have a static IP through my internet provider set up through my business.  I can connect to any of my devices at the house through this static IP provided by my internet provider.  Apple makes it pretty easy to do that.

Well  I agree with you.  and thats pretty decent.   have 1.6TH/s  all scattered through 3 different towns in 3 different palces.  i need them all in one area..  so its easier to manage.


And no matter aht ur switch is ull have collision domains.  Because if u have 10 miners on 1 switch and there ALL sending data at the EXACT same time to and frome..  That = Collision.      The only way u can minimize is to to run a switch that can operate at Half Duplex.    with say 10baseT

Run that to a mainswitch or router running 100baseT.  Or for better performance.  Run fibre from a switch to ur router to reduce collisions.


But every deivce that is connected to a switch is a collision domain the reason for this is because Switches usually operate at Fullduplex sending and recieving data at the same time.     Thus.. if 50 devices are connected to one switch and all 50 devices are sending and recieving data at the same time... You will than encounter collisions and issues with FRAMES being sent.


Thus reducing profit... Though for the average user this is something they wouldnt notice to much.  But for a System Admin like myself.  I would notice these things...   and I would fix it




The best bet in my opinion....   Is to buy a cisco switch but make certain to always disable the ports that are NOT BEING USED.       It took me ahwile to learn collision domains and switches and how they actually work.      


Just because you pay tons of money for ur switch doesnt mean ull get the best data speed.        Because now you gotta think.. okay.   what speeds should I use.



What cabling would I use to connect my miners to my switch... What cabling would i use to connect my switch to my router.. And than you have to take into the account that every device connected to a switch is a collision domain.          

When the Collision happens the Frames sit and wait at Layer 4(Transport LAyer)  untill the SYN-ACK is cleared by ur switch and its ready to lease the data to the switch.  





This may make no sense or you may think im wrong.  But i can 100% assure you that I am not wrong.    Proper Cabling and configuration can reduce many problems.






But wow man.       I bought like 8 Antminer S1s a few months ago.  paid for half.  got the rest for free because I lost contact with the seller.  
Been working with 1.6TH/s best I can.  trying to get another S3 but I;ve been limited for funds with bills and school and all that.


But in the end.



After seeing everyone server setup and cabling or these rigs.. Shit mine is going to destroy the hell out of theirs.. Super Neat, compact, but good enough to provide the proper results for my Hash speed




lol wow im a nerd.




My 2 Favourite hobbies are Remote Controls and Bitcoin Mining...  Computer (IT)  Doesnt count

Actually, if BTC price goes high enough; like $900.00 per BTC.  I may end up getting my power company to put a 240V/400 AMP service meter on the side of my house.  That's in addition to the 240V/200AMP service meter I already have.  My entire recreation room would be used as a warehouse with no costs for lease/rent each month.  I would have two (2) 14 inch exhaust fans in each of my windows in the recreation room to suck out the heat.  My recreation room is 13' x 25' with 8' ceilings.  We never spend time in the recreation room anyway.  We spend most of our time in the family room upstairs on the main level.  I have a split foreure (spelling) house.

The 400 AMP service meter would provide another thirteen (13) 240V/30AMP - 7,200 WATT circuits; enough to power a total of 65 S4's with PDU's to go along with the 25 S4's I would have running on the 200 AMP service meter.  Ninety (90) S4's at 2 Th/s each would be 180 Th/s.  Not bad for a HOME farm without the additional costs for leasing/renting a warehouse/building somewhere.  Also, I would want it at the house to avoid worries about a potential burglar or arsonist.  I already have video/audio surveillance set up at the house connected to the internet with a static IP.  So, I can watch and listen in if I happen to be away from the house for a while or on vacation.

IF BTC got as much as $2,500.00 each, THEN I would get a warehouse somewhere with approximately 4 employees and have as much as .4 to .75 Ph/s.  Hell, I might consider building a 30' x 30' shop in the back yard to put all of that in if BTC got up to $2,500.00 each.  If BTC went to crap afterwards, I would convert it into a wood working shop for my hobby of building furniture and painting portraits of people.  I'm actually a pretty damn good artist.

Yes, dreaming is fun at times.  It would be even more fun if it came to pass.  Nothing wrong with dreaming.

By the way, if you have damn good switches you don't have to worry about collisions/crosstalk.  My TP-Link switch is a damn good switch!  I would have 2 of those with all ports filled to the max if I had the 90 S4's in my house as I had mentioned previously.
