How do I use the current usage data to predict future growth?

I am taking up responsibility as a capacity planner. Currently, I have created automated reports that can tell me the exact usage of each tier and host for all our boxes. This data is obtained and stored every day. Can you share how I can use the data to analyse utilisation and predict the future growth in a better manner? Putting it the other way, what would be typical questions I would need to answer to make the most of the data that I have. Or what would typical capacity analysis and reporting look like...? Thanks for your time.

Thanks. We'll let you know when a new response is added.

Try taking some historical data and see if it can predict the actual present data. Look for outliers and what events might have generated those. Predict if there will be similar events that could create additional storage needs in the future. Become familiar with statistical predictions. The Excel functions of Slope & Forecast could become useful tools in your tool box.
