"EMC VMAX AF uses latest/greatest procs. Will never dedupe because it overruns them." - I have no idea what you mean here, unless you are saying the VMAX is so fast, that the processors can't keep up with dedupe? EMC runs them too hot? I think the really answer they will never dedupe is that would mean fewer sales dollars for EMC.
"HDS uses multiple procs--more than most. Best Practices still require Cache Partitioning and other measures to minimize the CPU impact." Can you explain why this is bad?
"Pure claims to use latest/greatst procs. Hasn't added a single feature in 4 years." I think their filer offering is certainly a new feature. Since they are new product, they don't really have anything else to add, as would be the case with all the legacy systems.
"- IBM V series--their #1 seller--no dedupe same reasons as EMC" - I don't understand the point you are trying to make about EMC, ergo I don't get the point with IBM (unless its about IBM making more money since their customers have to buy more disks)
"NetApp has numerous limitations with Dedupe, Compression, Thin, and so on." Huh? ONTAP 9 has a lot of excellent new features, and dedupe, compression and thin provisioning have been options with them for a long time, and are more impressive with AFF (I can say from experience). I think they continue to make great strides in this business.
Don't get me wrong, I have always liked what I have read about 3PAR (except the data loss part, which frankly has happened to every storage vendor at some point), but i don't get any of your points against 3par's competition here, they all seem to be explanation free.
3Par also seemed like the perfect aquisition for HP in 2010. I was an EVA customer then and got burned by the EVA team picking up and leaving after HP aquired compaq back in the day. HP was totally screwed by that. Not only could they not add new features to it, they couldn't fix bugs.
We had a DR event with one of our primary HP EVAs, and we quickly learned that without the Primary EVA being online, you couldn't make the destination EVA volumes writeable (or anything-able). We actually got HP people on site, and they couldn't figure out how to fix it, they just wanted to fix the primary array (which they did). It only made sense at that point to buy something to replace the EVA, and 3PAR was the perfect fit.
