Re: Rasberry pi - high density

Interesting! Knowing a pi costs approximately $35, then you need approximately $350 to get near an i5.. The smallest and cheapest desktop you can get that would have similar power is the Intel NUC with an i5 that goes for approximately $350. Power consumption of a NUC is about 5x that of the

As it turns out, I've been playing around benchmarking things lately using the tried and true UnixBench suite and here are a few numbers that might put this in some perspective: 1) My new Rapsberry pi (4 cores, arm): 406 2) My home i5-like thing (asus 4 cores, 16gb's from last year): 3857 3)

Freddy, did you get your test up ? I too am facing the same BGP scalability constraints as you are, and the only real viable solution seems to be filtering. snip I'll probably will setup a small test environment to see if this actually works as expected. Best Regards, Freddy

Rather then guessing on power consumption, I measured it. I took a Pi (Model B - but I suspect B+ and the new version is relatively similar in power draw with the same peripherials), hooked it up to a lab power supply, and took a current measurement. My pi has a Sandisk SD card and a Sandisk USB

Maybe I messed up the math in my head, my line of thought was one pi is estimated to use 1.2 watts, whereas the nuc is at around 65 watts. 10 pi's = 12 watts. My comparison was 65watts/12watts = 5.4 times more power than 10 pi's put together. This is really a rough estimate because I got the NUC's

Did I miss anything? Just a quick comparison. If those numbers are accurate, then it leans towards the NUC rather than the Pi, no? Perf: 1x i5 NUC = 10x Pi $$: 1x i5 NUC = 10x Pi Power: 1x i5 NUC = 5x Pi So...if a single NUC gives you the performance of 10x Pis at the capital cost
