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.
