It's still mind-blowing to me to think that a decade earlier this would have been a few racks. Now it just fits within 1U or 2U. What an insane world we live in.
Indeed! Now with Up 2-4TB of Memory, and 1-2 PB of SSD. All inside 1-2U. By 2030 we will have server with 1000W CPU. We are fundamentally close to be limited by cooling.
And I forgot to include this. We have 1U of Server that could replace 1 Rack. That is 40x density increase. I wouldn't be surprised if we could increase this to 80x to 100x within another 10 years.
If that is the case, why do we need more DataCentre? Wouldn't it be easier to retrofit existing DC. Sometimes these sort of hyper scale is just so big they are beyond my imagination.
