Hi All
Ive just subscribed here so go easy on me
Im trying to diagnose a slow running issue with a ProLiant ML370 G2 W2K file and print server here at work, the main complaint from users is long delays in opening / saving documents (30-60 sec to open a small word doc for example) and slow running of databases.
Ive been searching for the root cause and noticed that the Average Disk Queue Length goes absolutely haywire on both drive arrays, peaking up in the millions(!) for a second or two then immediately coming back down again to zero, then repeating this continuiously. From what Ive read Microsoft say this queue should generally be between 0 and 10 (1.5x the number of HDD spindles in the array?) so I do believe that something is going awry somewhere. Because its doing it on both arrays (c: logical drive is 2x9Gb mirrored, d: is 4x36Gb RAID5), we concluded it may be a hardware issue with the RAID controller so had that swapped out, but that has not helped.
Before we swap anything else out I was hoping that you guys may be able to give some inspiration on what to look at next?
thanks
Chris
