Hello all,
Tom Judge a écrit :
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].
The SAS-5 known to have very poor performance (1Mb/s 100%busy) under
certain loads (cvsup).
I have something that looks like the same kind of problem, on a PE860
with SAS-5i and two SATA 160GB HD in RAID 1.
The server is a webserver and "top -S" shows very high CPU usage (idle is
0%, user CPU is 40%, system CPU is 60%, interupt is 0%) when running 60
concurents httpd threads...
I've browsed quite a bit arround this issue and ended in this thread
(plus several other threads arround the same problem).
I've just realised Dell has released a new firmware on 17 of april
(beware of long URL) :
http://support.euro.dell.com/support/downloads/download.aspx?c=fr&cs=RC1077983&l=fr&s=pad&releaseid=R149732&formatcnt=6&libid=0&fileid=199166
Has anyone tried it ?
Best,
David.
