By the way, Promise hasn't released firmware for the Channel version of the Ex10 series for more than a year now. Its likely that these units are very very close to reaching end of life / end of support status with promise. Either way, trust me when I tell you that when it comes to VMware, there are MUCH better options on the market than any Promise RAID solution. The company I work for now sells JetStor brand storage made by Advanced Computer and Network Corp - http://www.acnc.com and I have found that even their cheapest stuff is at least 5x faster. My favorite JetStor chassis is the 724iFD which is similar to the Promise Ex30 series only MUCH better (it's got VAAI support!). Before you go spending $2500 to convert your very old Promise unit, please consider spending a few more bucks on a new JetStor unit, you will be much happier.
