Hi! very interesting topic for which I have a few questions: in a typical DC, in each rack are 2 PDUs for redundancy purposes. My question is: when both PDUs are connected but only one is active (in the sense that it provides active power) how the power consumption is calculated for that rack? Is it that one PDU is supplying max power capacity and the other is idle? If idle, will still consume some power; how much that would be?

normal Colocation run at about 10kW so 1.5 is a bit low. 150 Racks is a lot of space, which could be down sized to 23 racks and 27 racks if all server and storage gets packed together. most of this load can even be run in the cloud where somebody else hosts the server and we just need to worry about rightsizing our Instances to handle the load. No more datacenter building needed on our site.

Thank you for the video, I have a question about the power rating of UPS, for example when we say a UPS of 250kVA is it the power that will be delivered at the output of the UPS or it is the input power that will be consumed at the input of that UPS?
@gogotraining36044 жыл бұрын
Thanks for the great question Abdeslam. 250 kVA is the input power consumed at the input to the UPS. What is delivered to the output of the UPS depends on the power factor of the UPS. A 250 kVA UPS with a power factor of .8 will deliver 200 kW of output. There are other factors, of course. The UPS can consume as much as 20% of its input power to recharge the batteries.
@abdeslammerazka30034 жыл бұрын
@@gogotraining3604 Thanks for replying to my question, As you know most UPSs nowadays have a unity power factor at the output so I think we should consider only the effeciency of the UPS plus the percentage (20%) reserved for recharging the batteries to get the power delivered at the output of the UPS, am I right?
@gogotraining36044 жыл бұрын
@@abdeslammerazka3003 It depends on the type of UPS. In a double-conversion UPS (most common), the AC power is converted to DC and then back to AC. There is a loss whenever you convert the power, so the power in will be greater than the power delivered to the output.

Hey, Cooling Efficiency is most of the time 2-3X (EER) so why need that much power for Chiller or Precision AC ? if server racks power is 255KW heat load would be also around 255KW so need an air cons that will support 255KW+ cooling capacity and power consumption will be almost 1/3.

@gogotraining36043 жыл бұрын
Thank you Qasim. PUE (Power Usage Effectiveness) is calculated by : Total Power In / Total Power used for IT equipment (servers, network) PUE is used to see how efficiently your infrastructure is running (power, but cooling primarily). The best PUE would be 1.0, meaning all the power coming into the data center is being used to power the IT equipment. A value of 2.0 would mean of all the power coming into the data center, only half of it is powering IT equipment. The other half is overhead (losses due to power or cooling infrastructure).

@GogoTraining I have another question please. How to improve PUE value, best option is to reduce power consumed by cooling. Another factor is to move to virtualization from use of physical server. But P2V will reduce the power consumption of data center but it will worse the PUE as critical load denominator will be less so value will be high
@gogotraining36043 жыл бұрын
@@qasimnaseer1 In the example Dave shared, he showed a critical load of 225 kW. This is the IT load in the PUE calculation. So to calculate PUE in this example, divide total load (703 kW) by IT load (225 kW) to get a PUE of 3.12. The numbers Dave used were very conservative to show how we would go through the process of sizing equipment and calculating overhead. Ideally, we would want to see our PUE as close to 1.0 as possible.

How do you think. What will be a power consumption on 7000 racks an 100000sqf?
@gogotraining36044 жыл бұрын
Hi Oleg. The size of the data center does not impact the power consumption (except for the amount of cooling needed). The number of racks is part of the equation, but the power consumption of each rack is also needed for the calculation. If each rack consumes 10 kW, you will start with 70,000 kW if required power. You then have to calculate cooling cost, losses in the UPS, and lighting, as well as calculating for peak power draw. You can use the sample calculations in the module but start with 70,000 kW as your starting point for the calculations.
