Regarding NFS vs Samba - NFS *does* guarantee file state, it sounds like what you're talking about is the synchronous IO part of the equation. Regardless of turning write syncs on and off and mount options or SMB vs NFS, I would definitely recommend not pushing cache file writes across a network at all

This is really great. Balancing heat management and noise goals is always a delicate tightrope to walk. That server rack arrangement, especially if well and truly loaded with drives, must really pump out some heat too. I used a Commander Pro in a build last spring and it really gives you a lot of options. This is the first time I've seen it managed with a script like this.

thanks for shareing your exprerience and the software for controlling, really appriciate it.

damn yo, you're running some molex to sata adapters. Too spooky for me bro!

I have an NZXT Grid, which is a similar product. I'm not super happy with how I have it set up in Linux, but it looks like Liquid supports it, so I'll definitely have to try that out! EDIT: Toward the end of the video, there's a mention of the NZXT one. Mine has six outputs incidentally, but I think the Commander Pro is probably a nicer size for this application anyway.

I have the Commander Pro as well. And it has worked great for me for several years now. But a word of warning. I would not recommend powering more than 2 fans per port on it. As I managed to kill one of the ports by running 3 fans there. And that is despite Corsair rating each port for 1A, and 3 fans being supposedly well below that rating... So if you wanna use more than 2 fans per port, then i suggest getting a fan splitter with a molex power connector and separated PWM control connector. Which will then allow you to power the fans via molex only, and use the PWM control on the Commander to control them.

@TechTangents

3 жыл бұрын

Thanks for the heads up! The only fans that are on splitters are the 80mm ones and according to Noctua ( noctua.at/en/nf-a8-pwm/specification ) those only draw 80mA each. So I should be good. Each of the industrial fans are connected to their own port because I did want to make sure I spread the load. So if the fans are ever at 100% the most that they should draw is 0.3A per port.

Impressive! I am still looking for a good build-in temp controller for my retro pc build.

I might have to do this for my unraid box!

I think those temperature sensors are more of a gratis thing. They give you the option of controlling the fan temeprature according to the atmospheric air temperature inside of a case, though this is sub-optimal. Those temp sensor ports are much more useful when connected to a G 1/4" fitting with a thermal sensor inside to directly measure liquid temperature.

Sweet.... You found the way...

Put in the damn fan controller, Shelby.

The thing about electronics that I've found, with respect to the operating temps is that you're better off with a higher sustained temp than a large variation constantly occurring. So if you heat-cool-heat-cool, etc; vs just keeping something medium-to-high heat, you should be OK with the medium to high heat, instead of constantly varying temps which can cause all kinds of issues. Expansion and contraction are more dangerous over time than consistency.

14:00 you could always use the magic of... mathematics and analysis! :D

The Compaq hat is baller AF.

Get an Aruba S2500 switch it has 4 10GB SFP ports and either 24 to 48 POE and fairly easy to setup. There is a guy on here that shows you how to set it up they range from $98 to about $200 on ebay. I just bought another switch to stack it and then going to stack with fiber so I can move my server down stairs also you can now use nvidia on esxi and other hypervisors with a workstation cards.

13:45 - The sensors from smartctl only updates every 4 minutes. I'm not sure if you can change that. My 16TB Iron Wolf Pro NAS drives idle at just under 40 but have an over temp warning at 60. Maybe once a day they get a big write. Either way I keep direct airflow on them, just to be safe.

That was a great result! I'm sure there's a better control algorithm that would prevent the fan speed oscillation, but at least it's working way better than the onboard fan controller. It's a shame about the RAID 0 speed. I feel like you'd get a better result just connecting it to the onboard controller and using software RAID. Also, I really hate those plastic Ethernet connector boots. I've found they make it really difficult to press the latch and result wiggling the connector too much. Panduit make a "snagless" connector, which don't need a boot since the latch is bent back down to prevent it from getting snagged. The model number is MP588 (-C for the 100 pack). They're listed as CAT 5E, but they work just fine with CAT 6 cable. Their CAT 6 connectors (SP688) were more expensive, although I've never tried to run the 5e at 10G. They also have CAT 6A connectors (SP6X88), but I haven't bothered looking at the price for those.

I don't really have the option to connect them to the motherboard. Every single SATA connection I have available is being used by the 22 drives I have in there(plus two empty bays). The SSDs are being used as a temporary work space for projects for things like proxies and render output (so I don't render to the same drives I read the BRAW files from causing the heads to thrash) which means the data that's stored on them is never that important. The SAS controller they are connected to barely supports JBOD(I'm using mdadm software RAID) and has to "initialize" drives to pass them through which wipes the data off of them. I've had drives drop out of the JBOD for seemingly no reason before and had to reinitialize them. So leaving the temporary content holding SSDs on there is the safest option until I can replace it.

@@VorpalGun You are spot on. Tuning PID to control a system with a lot of inertia is EXTREMELY painful. I was paid to to it on a scientific reactor, and it sucks. In electronics, this is all so easy as the time constants are in the seconds range. With the reactor it took around half an hour to test a parameter set. It still is not tuned that well and overshoots. Problem is that with higher temps, the system needs different tuning parameters (Mind you, this was an isolated system, so with lower temps it worked "integrating", storing whatever heat I pumped into it. With higher temps the radiation heat got high eough that the system needed to compensate for that - completely different tuning params.) All in all - science does not lie - PID will work, however be prepared to spend a LOT of time tuning it. for an application like Shelby's, it's better to just stick with a classic linear curve (P regulator).

@@VorpalGun Correct, therefore we use PI(without the differential part) algorithm/characteristic when it comes to such simple and slow changing tasks like temperature control. What the other guys say (like "EXTREMELY painful" [1]) is just the lack of knowledge, not knowing the math behind and experience in practice. We are managing whole industry plants with control circuits from mechanical over analog to digital PI(D) types. Control theory dates from the 19th century(!), when the theoretical basis for the operation of governors was first described by James Clerk Maxwell. That this is something new, "magic", unknown or difficult just shows the unfamiliarity with the topic and gave me a good laugh. Also the inexperienced mostly lack the knowledge when NOT to use some more complicated technology versus simple solutions. As Trey Dempsey said in the other comment, a simple switch with hysteresis may be sufficient ... which is done so by decades. As thermal energy is unavoidably inert, a swing of the actual-temperature can't be really avoided. And again, for many use cases including hard disc temperature control, a swing of f.e. 5° just: DOESN'T MATTER! (Hey, this was not to discourage the hobbyist from playing with any kind of fancy control-device. More the contrary, DO IT! Gaining experience is never wrong.) [1] I really don't know what this strange fear-mongering attempt should tell us. Or even the comparison of some(!) kind of reactor versus this clearly specified use case here made me cringe. WHY? Well, the physical parameters are actually that what makes each solution different. I don't know how boasting with an edge case story will help anyone here. Better read a book about the topic ... which is simply too much for most people, who just want their cooling running. Oh and guess what, the guys at corsair did optimize the controller exactly for the use case what it is built for. Modern devices even have automatic optimization routines. Like ovens, most commercial controllers and what not for things I did not mention here ... many of them are capable of automatic-optimization/parameter-finding, since ... you guessed it?: Decades! Anyway thank you and here are 9 out 10 **facepalms** for your comment, Railroad.

Another point: There is a reason, why server hardware fans come in a bunch, are independent from each other and are directly connected to the supply lines: Reliability! This solution ( from Tech Tangents, which I don't want to downplay ... and I like, because it shows maker-brains and enthusiasm) introduces multiple failure points. Like the same(!) system controls the "life safer" by software(!) ... This alone could be a good template for a tech-thriller-novel:) Then, in the 100% fan standard usage case it is very unlikely, better say impossible, that all fans stop working while the machine is running. No problem here, just some problem or hardware failure with the corsair device ... And when unattended ... results into fried components. I know, the reason for all these modifications was to keep the server silent. But there are many alternatives. For the same price ... buy a Hilti drill-bit and put the server in a separate room ... as an expert would do it (with all the other advantages I won't discuss here ... use your own brain!). Ask someone how soundproofing is done? If that server dies, which will be more and more likely as we introduce more and more unusual botches, it will be very silent ... which maybe includes the job and the income, that is no good prospect, or? Well, sorry. That was my fear-mongering attempt. Just ignore that. After all, we know that all of our DIY prototypes are the most reliable things in the world and will never let us down ... :P

The first fan also shows as spinning at 3,000+ RPM which isn't possible. So it's probably just a display issue but it is still only experimentally supported.

Use an Arduino. It can control the fans and send a signal to the server saying everything is ok.

maybe you could strap some Peltier coolers directly to the drives lol

This would move the heat from the drives, but then you would still need to get rid of it

Peltier devices aren't worth the time or effort given how little of an effect they actually have vs. water alone or air alone, especially for how much more energy they guzzle than straight air or straight water for negligible temp improvements. If one wanted to do subambient cooling for OCing or whatever, they'd be better off running a liquid loop through a refrigeration-based mini chiller sled than adding a peltier device in as a refrigeration-based chiller is orders of magnitude more efficient than a peltier device.

LTT rolling in their sleep.

Hurry up getting storage, cause thanks to the new coin Chia, drives will get as elusive as GPUs and will also get much more expensive... We will have to see how bad it actually will get. But due to the chip shortage, lack of SSD controllers... I think it will be just as bad as with GPUs at the time.

Controlling temperature is a complex problem.

12v rail: 6.21v... yeah... either an issue with the device, or the power supply is not happy 😂

My motherboard once glitched out somehow and reported all voltages as being 2 times higher, 24V on 12V line.

did anyone else not get a subscription entry for this?

Got mine, resub too him. Had that happen on lgr lol but worked after that.

hearing that google ran their drives into the 60's without much difference in failure rates makes me feel a bit better that the 3 18gb 10k SCSI drives in my compaq P3 machine that run in the high 60's low 70's wont die within a day lol. (not that running them so hot is good for them anyway, i dont care for the drives THAT much...)

​ @Tech Tangents .. I'm going to address the elephant in the room here..... Water Cooling those CPU's would not reduce the speed and number of fans ???

Water cooling the CPUs would only remove the fans on the CPUs because everything else in the system still needs active cooling. The HDDs especially will always have to have fans and need the most powerful fans to pull air through them. Additionally, water cooling a server is a bad idea since you are adding an element that can fail and take out the whole system. I've never done it before and it would be a terrible idea for my first water cooled system to be a server.

​@@TechTangents Yes.. but.. keep in mind that those 4 fans attached to those huge aluminum radiators....... do not do anything for you HDD's........ they actually blow hot air into the CPU radiators... hot air coming from the HDDs........ I think that even with 2 Water Cooling radiators (one for each CPU) stacked one on top of the other.. back there in between the PSU and the GPU...... you're going to have less noise.. and better cooling for thouse CPUs... and less noise.. (WC fans always run slower)........ WC is a technology more than tested .. as always the expensive ones.. not the cheap ones... ask any gamer .......... aaannd.. you recover a huge amount of space there in the middle of that box...... to put the SSDs there.. and free up some space at the front for better air circulation in the HDD's bays....

so, the fan-upgrade costs more then the server hardware itself? * kappa *

A bit weird. You went with corsair, imho they produce shitty products that are not reliable so I am not surprised

You need AC it seems. Lol. Nice job.

put rgb in your sever for lols

how about you get that data general working or admit that you failed

Servers are not meant to be quiet.

While that's generally true, i still swapped out the Fans on my two supermicro servers for more quiet ones. In a home Environment this comes down to personal preference

dumbest thing i've ever heard. "Hi, i have a 4U rack mount server and i want it as quiet as possible" IT'S A SERVER IT'S SUPPOSED TO BE LOUD AS F. You can get long ass cables and run them from the other room. Single active usb extension and a really long SVGA cable with a booster would be fine. then you wont have to be near your server.

Nothing wrong with making it quiet if temperatures are in check.
