I dont think you can change that - Its dependent on the NAS control LUN sizes which depend on the version of DART  what you can do is to change the time interval - if you poll less often you can store longer periods  Rainer
It is our experience that in Celerra Monitor we can save statistics for up to 12 weeks. This has to be set individually for each resource that we want to monitor.   Three questions.  1) Why only 12 weeks of data?  2) Why do we lose these statistics when we reboot the control station? 3) How can we save statistical data on the nas control station so it survives a reboot?   Thanks, Marty Meadows
