The XP doesn't look great next to its peers - really?
Well as theres only really EMC DMX, and HDS USP (which is the same tech that both HDS and HP get from Hitachi), I fail to get that comment - its a seriously good box, very stable, scalable and performant, and commercially HP are a lot more successful at selling them than HDS (in terms of frames sold)
surely you're not going to suggest IBM XIV or DS8000 or whatever it is now are up there as well?
I tend to agree about EVA though, well due an overhaul with things like true Thin Provisioning (sorry Matt by DCM ain't THP) and de-dupe (which unfortunately HP seem to be burying their head in the sand over except in the VTL space) as well as from a hardware perspective, but one is coming which will see it claw some ground back. Snapshot software is OK but needs better application integration ala NetApp as its largely script based at the moment.
However it does have some very good benefits from a usability and management perspective, general provisioning is so easy a numpty like me can configure and provision storage to a host in about 4 or 5 clicks.
PS IBM also have a very confusing product line with overlap so seems harsh to penalise just HP on it they have various DS models, N-Series (NetApp) and XIV, what do you buy there for a midrange type project? answers on a postcard
The clearest defined product lines to me appear to be from NetApp, HDS and probably EMC
