DL 380 Disk Utilization

Hi!
I try to measure utilization of server disk subsystem with Microsoft Performance monitor. In particular, i measure Avg. Disk Queue Length counter. What is a normal value fot this counter if i have such disk subsustem configuaraion: Smart Array 6i controller with 3 disk in RAID 5 array?

Hi,

Apart from other things it will also depend on actual utilization at that particular time. So you should also mention the application it is used for & the no. os users accessing the system at that point.

HTH,

Yes, I understand that. But i see from physical disk point of view - how much must be value of Avg. Disk Queue Length counter in order to say that disk is utilized for 100 percent and i must enhance disk subsystem?
