We get figures back of 16.980ms, we notice disk access seems to be sluggish. I read in another post </SPAN>that anything over 15ms is considered high, would this be the case? Our disk storage is from a SAN stoage system. </DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;"><BR /></SPAN></DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;">Any information would be helpful or even point me in the right direction to some chart performance guide.</SPAN></DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;"><BR /></SPAN></DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;">Thanks<img id="smileyhappy" class="emoticon emoticon-smileyhappy" src="https://communities.vmware.com/i/smilies/16x16_smiley-happy.png" alt="Smiley Happy" title="Smiley Happy" /></SPAN></DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;"><BR /></SPAN></DIV><DIV><SPAN style="font-family: arial, helvetica, sans-serif; color: #333333;">J</SPAN></DIV></BODY></HTML> Tue, 18 Sep 2012 16:01:48 GMT https://communities.vmware.com/t5/VMware-User-Group-VMUG/VCenter-4-1-Disk-Latency-Question/m-p/2643473#M326 JohnLong 2012-09-18T16:01:48Z Re: VCenter 4.1 Disk Latency Question https://communities.vmware.com/t5/VMware-User-Group-VMUG/VCenter-4-1-Disk-Latency-Question/m-p/2643474#M327 <HTML><HEAD></HEAD><BODY><P><SPAN style="font-size: 10pt;">Hi John, a disk latency inferior to 20 ms is a good scenario.</SPAN></P><DIV id="_mcePaste">The default treshold for Storage DRS is 20 ms of latency in the Datastore, so 16 ms is a good responce.</DIV><DIV> </DIV><DIV> </DIV><DIV id="_mcePaste"> </DIV><DIV id="_mcePaste"> </DIV><DIV> </DIV><DIV>Bye</DIV><DIV id="_mcePaste"> </DIV><DIV id="_mcePaste"> </DIV><DIV id="_mcePaste"> </DIV><DIV> </DIV><DIV>--</DIV><DIV id="_mcePaste">Rocco Sicilia</DIV><DIV><SPAN style="font-size: 10pt;"><A class="jive-link-external-small" href="http://www.roccosicilia.it">http://www.roccosicilia.it</A></SPAN></DIV></BODY></HTML> Sun, 07 Apr 2013 16:22:55 GMT https://communities.vmware.com/t5/VMware-User-Group-VMUG/VCenter-4-1-Disk-Latency-Question/m-p/2643474#M327 rsicilia 2013-04-07T16:22:55Z
