It is at this point that I am reminded of the wisdom of former FTC Commissioner Orson Swindle, who was testifying before Congress on the subject of spam when he said "We need a couple of good hangings here." It was true in 2003 (which is I believe when he said it) and it's still true now. Fines, whatever they are, will be evaded and bargained down, companies will be dissolved and reconstituted, money will be laundered, and the problem will persist. ---rsk

Energy Efficiency - Data Centers
by Rod Beck 18 Dec '19

18 Dec '19

Energy efficiency is a hobby of mine and most of my properties embody Passive House Technology. This led me to wonder what is the inefficiency of these servers in data centers. Every time I am in a data center I am impressed by how much heat comes off these semiconductor chips. Looks to me may be 60% of the electricity ends up as heat. Regards, Roderick.

Well, the fact that a data center generates a lot of means it is consuming a lot of electricity. It is probably a major operating expense. And while it may be efficient given current technology standards, it naturally leads to the question of how we can do better. Thermodynamics is only part of the picture. The other part is economics. If you see a lot of heat being produced and it is not the intended output, then it is anatural focus for improvement. My guess is that a lot of corporate research is going into trying to reduce chip electricity consumption. So my gut feeling might still be relevant. It is about the level of energy consumption, not just the fact electricity becomes disorderly molecular gyrations. ________________________________ From: Thomas Bellman Sent: Wednesday, December 18, 2019 9:57 PM To: Nanog(a)nanog.org Cc: Rod Beck Subject: Re: Energy Efficiency - Data Centers On 2019-12-18 20:06 CET, Rod Beck wrote: > I was reasoning from the analogy that an incandescent bulb is less > efficient than a LED bulb because more it generates more heat - more > of the electricity goes into the infrared spectrum than the useful > visible spectrum.

Which for a lighting source would be measured in lumens within the visible spectrum. If you put in 300 watt of electricity into a computer server, you will get somewhere between 290 and 299 watts of heat from the server itself. The second largest power output will be the kinetic energy of the air the fans in the server pushes; I'm guestimating that to be somewhere between 1 and 10 watts (and thus my uncertainty of the direct heat output above). Then you get maybe 0.1 watts of sound energy (noise) and other vibrations in the rack. And finally, less than 0.01 watts of light in the network fibers from the server (assuming dual 40G or dual 100G network connections, i.e. 8 lasers). Every microwatt of electricity put into the server in order to toggle bits, keeping bits at their current value, transporting bits within and between CPU, RAM, motherboard, disks, and so on, will turn into heat *before* leaving the server. The only exception being the light put into the network fibers, and that will be less than 10 milliwatts for a server. All inefficiencies in power supplies, power regulators, fans, and other stuff in the server, will become heat, within the server. So your estimate of 60% heat, i.e. 40% *non*-heat, is off by at least a factor ten. And the majority of the kinetic energy of the air pushed by the server will have turned into heat after just a few meters... So, if you look at how much heat is given off by a server compared to how much power is put into it, then it is 99.99% inefficient. :-) But that's just the wrong way to look at it. In a lighting source, you can measure the amount of visible light given off in watts. In an engine (electrical, combustion or other- wise), you can measure the amount of output in watts. So in those cases, efficiency can be measured in percent, as the input and the output are measured in the same units (watts). But often a light source is better measured in lumens, not watts. Sometimes, the torque, measured in Newton-meters, is more relevant for an engine. Or thrust, measured in Newtons, for a rocket engine. Then, dividing the input (W) with the output (lm, Nm, N) does not give a percentage. Similarly, the relevant output of a computer is not measured in watts, but in FLOPS, database transactions/second, or web pages served per hour. Basically, the only time the amount of heat given off by a computer is relevant, is when you are designing and dimensioning the cooling system. And then the answer is always "exactly as much as the power you put *into* the computer". :-) /Bellman

I was reasoning from the analogy that an incandescent bulb is less efficient than a LED bulb because more it generates more heat - more of the electricity goes into the infrared spectrum than the useful visible spectrum. Similar to the way that an electric motor is more efficient than a combustion engine. ________________________________ From: Thomas Bellman Sent: Wednesday, December 18, 2019 7:47 PM To: Nanog(a)nanog.org Cc: Rod Beck Subject: Re: Energy Efficiency - Data Centers On 2019-12-18 15:57, Rod Beck wrote: > This led me to wonder what is the inefficiency of these servers in data> centers.

What are you expecting the remaining 40% of the electricity ends up as? In reality, at least 99% of the electricity input to a datacenter ends up as heat within the DC. The remaining <1% turns into things like: - electricity and light leaving the DC in network cables (but will turn into heat in the cable and at the receiving end) - sound energy (noise) that escapes the DC building (but will turn into heat later on as the sound attenuates) - electric and magnetic potential energy in the form of stored bits on flash memory, hard disks and tapes (but that will turn into heat as you store new bits over the old bits) (I'm saying <1%, but I'm actually expecting it to be *much* less than one percent.) This is basic physics. First law of thermodynamics: you can't destroy (or create) energy, just convert it. Second law: all energy turns into heat energy in the end. :-) You are really asking the wrong question. Efficiency is not measured in how little of the input energy is turned into heat, but in how much *utility* you get out of a certain amount of input energy. In case of a datacenter, utility might be measured in number of database transac- tions performed, floating point operations executed, scientific articles published in Nature (by academic researchers using your HPC datacenter), or advertisments pushed to the users of your search engine. There is another efficiency number that many datacenters look at, which is PUE, Power Usage Effectiveness. That is a measure of the total energy used by the DC compared to the energy used for "IT load". The differece being in cooling/ventilation, UPS:es, lighting, and similar stuff. However, there are several deficiencies with this metric, for example: - IT load is just watts (or joules) pushed into your servers, and does not account for if you are using old, inefficient Cray 1 machines or modern AMD EPYC / Intel Skylake PCs. - Replace fans in servers with larger, more efficient fans in the rack doors, and the IT load decreases while the DC "losses" increase, leading to higher (worse) PUE, even though you might have lowered your total energy usage. - Get your cooling water as district cooling instead of running your own chillers, and you are no longer using electricity for the chillers, improving your PUE. There are still chillers run, using energy, but that energy does not show up on your DC's electricity bill... This doesn't mean that the PUE value is *entirely* worthless. It did help in putting efficiency into focus. There used to be datacenters that had PUE numbers close to, or even over, 2.0, due to having horribly inefficient cooling systems, UPS:es and so on. But once you get down to the 1.2-1.3 range or below, you really need to look at the details of *how* the DC achieved the PUE number; a single number doesn't capture the nuances. /Bellman
