<div dir="ltr">I've tested about 12 different Dell servers. Ony a couple of them have Idrac express and all the others have Idrac Enterprise. All the boxes with Enterprise perform poorly and the couple that have express perform well. I use the disks in raid mode on all of them. I've tried a few non-Dell boxes and they all perform well even though some of them are very old. I've also tried disabling Idrac, the Idrac nic, virtual storage for Idrac with no sucess..<br><div><input name="virtru-metadata" value="{"email-policy":{"state":"closed","expirationUnit":"days","disableCopyPaste":false,"disablePrint":false,"disableForwarding":false,"expires":false,"isManaged":false},"attachments":{},"compose-window":{"secure":false}}" type="hidden"></div><div class="gmail_extra" style="display:block"><br><div class="gmail_quote">On Mon, Feb 26, 2018 at 9:28 AM, Serkan Çoban <span dir="ltr"><<a href="mailto:cobanserkan@gmail.com" target="_blank">cobanserkan@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I don't think it is related with iDRAC itself but some configuration<br>

Did you check battery of raid controller? Do you use disks in jbod<br>
mode or raid mode?<br>
