Operation Manager data interpretation

[ajay_nabh]

Hi Guys

I have recently installed DFM and Ops Manger for my active active 2x FAS3040. I am seeing Latency over 20 millisec and even 35 ms on some of the LUNS. what should I make of this, good or bad?

Is there any doc which I can follow to find out more about what is acceptable level of Latency? also wanted to know what is max IOPS i can have on FAS3040?

Please suggest your experiences and if any doc to read in details

Thanks

Ajay

What application are you running? Is it over iSCSI or FCP ?

What is your Disk type and RPM FC or SATA 10K or 15K ?

With PAM cards or without?

Are your application users finding delayed response?

What is the Iops ?

With PAM

Are your application users finding delayed response?

Not Yet!! just looking through Ops Manager and thought I may ask this question

What is the Iops ?

Input/Output Operations Per Second

I just wanted make sure that systems are not slowing down also we need put another 200 users (Virtual citrix servers on NFS) on these 2 FAS 3040 controllers then there will be more load too. trying to be proactive..

thanks once again
