I'll share with you info on the lawsuits if you share info on when you used an EVA with an EnterpriseOne Database. If you're just getting fed info from HP/Hitachi reps - then you're being misled. Business Copy doesn't exist on the HP EVA - instead, they have Snapshot/Snapclone which is instantaneous. Its very, very cool - and it works brilliantly given the $100,000 pricetag that the EVA sells for from HP.
I'm sure that for certain large unix implementations, the XP series is very valid - I've helped implement a few in my time (including recommending the architecture for your company) - but I'd expect the XP12000 costs in excess of $2m. You can't SPEND that much on an EVA !
They're marketed by the same company - HP - and they're marketed to different computer models. Certainly the EVA is the fastest Microsoft SQL Server drive array that you can buy today - given that its actually faster than the XP1024 gives you a really good clue to how well the device works.
What I want to state though is that many companies get confused over what is a SAN and what is a NAS. The EVA and XP are Fibre-connected Storage that use a networking technology to connect drives to computers. Network Attached Storage, on the other hand, is little more than a USB connected hard drive in comparison ! NAS is DEFINATELY something to stay WELL clear of when looking for Database Storage - I've heard unbelievable nightmares about companies purchasing NAS devices for their database server. Believe me that drive configuration is EXCEPTIONALLY important when it comes to design of your EnterpriseOne architecture. Make a bad choice to try and save a little money ? You're going to suffer for it.
Given the fact that OneWorld costs usually at least $500,000 for the software, let alone the million or so for the implementation costs - I am always astonished at how little money is spent on putting a good architecture in place. Quite literally - if you get it right, then it really is a hands-off, black-box-in-the-corner solution. Get it wrong, and its going to be your worst nightmare every working hour !
