I want to know the answer to the following question:
Who makes PetaBox rack systems?
All the background I'm provided with is that "As of 2009[update], the Wayback Machine contained approximately three petabytes of data and was growing at a rate of 100 terabytes each month; the growth rate reported in 2003 was 12 terabytes/month.". Is that enough to answer the question?
Answer: no
