I stand corrected in that area. Tho, even upgrading to a LSI MegaRAID
9260 w/ BBU only brings you into the $1000 price range so unless
you're buying $1000 pizza boxes from Supermicro (not knocking the
brand, I use their kit at home ) that's still not even close to the
price of a decently spec'd IBM or HP server. Of course our spec comes
in around $6k per box. ;-)
