Re: Allow me to clarify...
Ill respond to a few of Dimitris comments... under what circumstances did the EF win?? We tested the first models out it was the slowest of any of the all flash arrays we tried in most of our tests(not that it was really slow). Now the new ones may be better, but in every test we threw at it it was usually close to the bottom other than some of the sequential tests where IBM lost out at the time due to only having 4 FC ports (new IBM ones have 8 I believe)
I like the E-Series I really do we have at over 10 of them all running 2TB drives, but we didnt buy them for flash arrays. Too expensive, support costs were too high and they were fast but others were faster, cheaper, and easier to setup and maintain(not that the e series are bad either compared to others).
FAS we got rid of all those too for pretty much the same reasons found faster cheaper systems.
