I like the article, but not your title. It implies that this trend of I&#x2F;O becoming highly performant has occurred recently, when in fact has been observed and studied for quite some time [0, 1]. Even before SSDs Gigabit ethernet was saturating CPUs needing to do more than DMA a packet, and I&#x27;m sure this trend continued for some time. The original title seems more accurate: &quot;Implications of the Datacenter&#x27;s Shifting Center&quot;, and references the existing trends in an insightful article.<p>[0] <a href="http:&#x2F;&#x2F;ucsdnews.ucsd.edu&#x2F;archive&#x2F;newsrel&#x2F;supercomputer&#x2F;11-09Gordon.asp" rel="nofollow">http:&#x2F;&#x2F;ucsdnews.ucsd.edu&#x2F;archive&#x2F;newsrel&#x2F;supercomputer&#x2F;11-09...</a><p>[1] <a href="http:&#x2F;&#x2F;nvsl.ucsd.edu&#x2F;index.php?path=pubs" rel="nofollow">http:&#x2F;&#x2F;nvsl.ucsd.edu&#x2F;index.php?path=pubs</a>
