With the onslaught of new applications brought on by our application development teams, utilization (memory, CPU, storage, etc.) "prediction" is critical for sound Infrastructure capacity planning. I would like to know how others in our industry address the capacity planning BEFORE the application is ever coded and hosted. Are there prediction models/software based upon anticipated user connections, transaction volumes, OTLP vs. batch ratios, etc.?

I have not found a solution to predict either memory or CPU utilization.
Storage is an easy task. This should be covered in the detailed design. The conceptual model of the DB should include all tables and the attributes that make up each row. Each attribute will have a data type and a length. Each table will have an estimated number of rows. To calcualte the storage required for each table is simple math. Of course this will change during development but it will be accurate enough to estimate the storage requirements

You can look at Patrol from BMC software (www.bmc.com). Apparently they have a simulation tool, which (after building some stats.) will allow you to do your predictions
