On Fri, 11 May 2007, Tom Judge spaketh thusly: -}> -- -}<SNIP> -}From the boot messages you have included below it seems that you have a Dell -}SAS-5i (Internal PCIe) controller and not a Perc/5[ie]. Tnx Tom. Yeah I knew that but didn't catch it in the Subject: The perc/5 is on another machine. -} -}The SAS-5 known to have very poor performance (1Mb/s 100%busy) under certain -}loads (cvsup). Hmm. Did not know that. Since I have a second machine just like this one, I also think I'm going to try pulling out the SAS 5i card and going with a software mirror package like gvinum or gmirror. Given the #'s Bill Moran posted and the horrible #'s you list above, this may be a viable option. -- Randy (schulra@earlham.edu) 765.983.1283 <*> Rain puts a hole in stone because of its constancy, not its force. - H.
