Questions about volume growth report

Hello everyone

I am researching a couple of questions for a customer on OM reports and I will break them out as separate posts.

On the Volume Growth ( http://10.42.135.36:8080/dfm/report/view/volumes-growth-rates?lines=20 ) I am being asked what is the calculation used to predict volume growth.

For example, if I have a 100 GB volume and the volume growth predicts that this volume will be full in 10 days and then I grow the volume to 200 GB, how will the calculation change?

Is there a moving average that is calculated? If the volume size changes, is the whole capacity growth changed?

Thanks, Emanuel

Emanuel,

"Days to full" calculation uses the trend line that is shown in Ops

Manager capacity graphs. The trend line is calculated by performing a

linear regression of upto 90 days data.

Daily growth rate of the volume is the based on slope of trend line,

days to full is (total space - used space)/(daily growth rate).

If the volume size changes, the days to full will be adjusted accordingly.

Thanks,

Raj.
