How a lot does a NAS server all the time on eat?

What influences the consumption of a NAS?

The consumption of a NAS is just not all the time the identical, actually, even having precisely the identical mannequin, consumption is just not the identical, as a result of it is dependent upon many components that we should keep in mind. Subsequent, you may see all the things that influences the consumption of a NAS:

  • Processor: it’s the major consumption issue, the extra highly effective the processor is, the extra consumption it normally has, though it is dependent upon the processor mannequin, so it isn’t doable to attract hasty conclusions. Typically new processors are way more highly effective than earlier generations, and have a clearly decrease consumption.
  • put in exhausting drives: The second consumption issue is the exhausting drives put in within the laptop. If now we have 4 exhausting drives put in as an alternative of two exhausting drives, we’ll typically eat round double. Every exhausting disk consumes between 6Wh and 9Wh at full capability, so it’s essential to take this into consideration when putting in extra disks in your server. Within the case of SSD items, consumption is way decrease, reaching a consumption of 1Wh. We should additionally keep in mind that in inactive state the exhausting disk consumes lower than at full capability, as well as, if we configure the NAS working system to hibernate, consumption might be virtually zero.
  • server utilization: The third consumption issue is the use we give to the server. If more often than not it isn’t used, then the consumption might be very low as a result of the exhausting drives might be in hibernation and the processor may even be idle. If we use it intensively, it can eat extra.

Now that we all know all the things that influences a server, let’s see some examples of consumption.

Examples of consumption in varied fashions

The very first thing we should keep in mind are the items of energy and electrical consumption. The ability is measured in W (watts) or in kW (1kW is 1000W), and it’s the unit that we will discover within the technical specs of the completely different servers, within the case of eager to calculate {the electrical} consumption we should multiply the worth of W by the point on. The unit of measurement for electrical energy consumption is Wh (watts per hour) and likewise in kWh (kilowatts per hour).

If a producer signifies that its tools has a consumption of 50W, it signifies that it consumes 50W in a single hour, so it has a consumption of 50Wh, and if we multiply this worth by 24, it signifies that this mannequin consumes 1200Wh or 1.2kWh day by day. If we multiply this worth by 30 once more, we will calculate how a lot the tools consumes month-to-month, about 36kWh. As soon as now we have the month-to-month consumption, we must multiply the worth of the kWh that now we have contracted with the electrical energy firm.

  • QNAP TS-253D: the producer tells us that it consumes 8Wh in sleep mode with the 2 exhausting drives suspended, within the case of being in operation at full capability it’s 12.5Wh.
  • QNAP TS-453D: the producer tells us that it consumes 11.5Wh in sleep mode with the 4 exhausting drives suspended, within the case of being in operation at full capability it’s 26Wh.
  • QNAP TS-653D: the producer tells us that it consumes 18.6Wh in standby mode with the six exhausting drives suspended, within the case of being in operation at full capability it’s 35.5Wh.

The one distinction between all of the fashions is the variety of exhausting drives now we have put in, as the primary one has two bays, the second has 4 bays and the final mannequin has 6 exhausting drive bays. As soon as now we have the consumption in Wh, it is sufficient to multiply by 24 to calculate the day by day consumption, and if we multiply by 30 once more we will calculate the month-to-month consumption to later calculate the month-to-month value.

Within the case of those examples, the TS-253D at full capability will eat 9kWh monthly, the TS-453D will eat about 18.7kWh monthly and the TS-653D mannequin will eat about 25.5kWh monthly. If we convert this to electrical energy value, and assuming that now we have a mean value of €0.15 per kWh consumed, the price is €1.35 for the TS-253D, €2.8 for the TS-453D and three €.8 within the latter case. After all, if now we have the TS-653D mannequin however we solely have two or three exhausting drives, logically we could have a decrease consumption, similar to that of the TS-453D mannequin, as a result of having the exhausting drives completely on and dealing is likely one of the issues that almost all have an effect on power consumption. Within the case of utilizing SSD items, the consumption is normally 1Wh at most.

In our case we’re utilizing a QNAP TVS-h1288X NAS server, in accordance with the producer it has a typical power consumption of 97.4Wh, which makes a month-to-month consumption of 70kWh and a price of €10.5 within the electrical energy invoice. Nonetheless, if we don’t have it filled with exhausting drives, the consumption is clearly decrease than these values. One of the best ways to measure how a lot a server consumes is to put a wise plug that has a consumption meter, on this method, it is possible for you to to get a day by day common of consumption primarily based in your use of the server.
