I could also use help with my mega-raid 150 question.  Don't know if I asked it 
wrong or it was the color shirt I was wearing.  I am unfortunately running with 
such a dearth of knowledge on the topic that I don't really know the right 
questions to ask when diagnosing a performance problem.  All I know is that 
there's very little documentation on this card, is even less documentation on 
the commandline tool to access/control the card and if it makes the most sense, 
I am perfectly willing to deep six the card on eBay and pick up a couple of 
reasonable speed serial ATA controller cards in its stead.

the only reason I want to try and learn more about the hardware raid is because 
the problems I'm experiencing with my virtual machines on this platform mimic 
problems a customer of mine is experiencing and if I can fix them just by 
changing how the raid controller uses the discs, then that is a huge win. 
Personally, I think it's something a little deeper because VMware server seems 
to go out to lunch whenever there is a backup in the disk I/O queue.  I'm 
seriously thinking about picking up esx as soon as the budget allows.

I just need some good solid advice on what path I should take.
