Hello,   Congrats on starting your own business, and with our Dell servers, thanks!   The tool that you manage to use, is an ideal guide to show you some figures in an ideal environment. So, the tool may provide you some information but in an actual environment, the actual figures may vary. So, to answer if the reported levels are correct, yes it is but in an ideal environment.   Yes, rack servers are more silent, funny ain't it? I have a very similar case about sound cap feature on tower and rack. Only 14G rack servers have sound cap option. That option enables you to have a more silent fan running. Though, do have in mind that, servers need good ventilation.   On power consumption, it's definitely draws more power when you have 2 CPUs, as the hardware needed to run 2 CPUs are also doubled.    My opinion best is to contact our sales rep if you need more information on the server's hardware.    Do let me know if you have other questions.
Hello!   I was comparing server characteristics (power consumption, noise levels, etc) with the Estimated Enterprise Infrastructure Planning Tool ( [URL]#/ ). (Very helpful tool by the way, just not so much advertised -- took me a while to find it.) So, I was comparing a T440 and a R440, that both host a Xeon 4210 and 2x280GB SATA SSDs (RAID-1 with PERC H740P) and 16GB of RAM. It all seemed reasonable to me, with the rack server pulling a bit more power and amps, but then I noticed something weird in the "Sound Power" section. It appears that the tool always reports more bels (so more noise) for the T440 server. For example, with a transactional load and CPU load of 30%, the T440 is said to produce 6.3 bels, while the R440 5.6 bels. I found this very weird since --from what I know-- towers server are designed to operate inside offices where noise is not very tolerated and since rack servers usually have smaller fans that need to spin faster and produce more noise. So, here are my questions: I am pretty new to servers and I wanted to host my wannabe business in a silent and energy-efficient model (I do not want to invest in rack enclosures or extra cooling).Initially, I was considering a tower, thinking that it would be most silent and most power efficient option, but looking at these estimations I am realizing that maybe the rack servers are more silent and that I should choose the R6415 as the most silent and energy efficient solution (although, it might be more expensive to buy...). I am a bit lost here, so any hints are welcome.   P.S.:The R6415 seems to miss the "Idle" workload mode. It would be nice to have a comparison of it against other servers in this mode. But I guess that would put those other servers in shame, because it would consume less than 50 Watts?
Estimated noise levels from Enterprise Infrastructure Planning Tool - are they 
correct?
