They seem to list the max cache as a total of the system as a whole, but the max cores of a single controller. Unless it's true that a 16-controller PS6500 has only one CPU core.
Since this article is about 3PAR it would of been nice perhaps if HP had corrected these folks in the RAID levels supported, I suppose perhaps RAID 0,1,5,6 is easy to understand(it is in fact what their own GUI refers to), but reality is of course it's more 0,10,50,60 -- dropping the 0 (from 10/50/60) would actually involve a significant amount of manual configuration that really nobody should ever ever ever feel the need to do).
Also one non trivial error perhaps
Part of their requirements for inclusion is
"It had to scale to support at least 60 TBs of raw capacity. " (bottom of page 6 right column)
(I assume that may be why it seems none of the new fancy flash startup folks are in the list?)
So jump to page 67 "X-IO Hyper ISE 7-Series"
Raw storage capacity (Max)
Should be at least 60TB right?????????????
Maybe it's a typo because it says 36TB
(Same goes for the other X-IO system - just happened to notice that didn't check many other systems)
