Sun Storage overall...
Well, even though the 25x0 storage seems to be much maligned, we've actually been quite happy with it.
I know they're dropping the j4x00 JBOD's - which we were actually starting to really like - this year (not to be confused with the j4400's they sell for 7000 series integration).
The 7000 series are fantastic boxes for what they are, but if you're wanting to run VDI or OLTP type stuff from them, you're still better off running in RAID 0+1 rather than one of the RAID-Z's. Physics still gets in the way.
We'll probably put in 4 to 6 of the 7410 arrays this year, and maybe a dozen 2540's. The 7310's and 7410's aren't quite as refined as a NetApp (we have a FAS3170, and we'll probably end up with a 2040 or two this year, so it's not like we've entirely drunk the Sun Kool-Aid) but if you need/want all the additional stuff Sun just includes for "free," there is no comparison in price. It's not even close.
I wish they wouldn't drop their low end though. I hate to think we're gonna be stuck using Dell (especially storage - the R610 and R710 aren't THAT bad once you get past iDRAC6 Enterprise's issues.) The AX4-5f is a mess compared to a 2540, and significantly more expensive.
