LOL I didnt mean to imply they are the same person. I just meant the TT may be able to help contibrute to an answer to the question. Yeah he covers the the IOPS stuff around 21:00-23:00 specifically 22:56 for the IOPS comparison which shows HP SAN does 4K/4K R/W vs Nutanix which does 11K/16K R/W. Its a great webinar, awesome to hear end user experiences of vendor kit, particularly when it makes a big improvement to cost and performance. Back to original question - why is Nutanix faster at IO ? Was it apples vs apples for the backend drive components? How much read+write IO cache is available on HP SAN vs Nutanix? Was there a change in SAN transport mechanism and host logical presentation?
