Someone would need to do disk usage forecasting based on historical data. The request for adding/dropping disk space should be based on the results of the above mentioned forecast in conjunction with the estimate of how much disk space would be needed to accommodate "non-typical" future usage. The person in charge should be actively involved with the business to figure out those "non-typical" changes (things like rapid product/geographic expansion, exit from markets, etc) - no formula or process would be able to get that information for him/her. I personally use simple linear regression for forecasting, but I am sure there are many other good methods. If you use Oracle Enterprise Manager (OEM), you can check my presentation -http://iiotzov.files.wordpress.com/2011/08/iotzov_oem_repository.pdf to see how I do it. Please note that you can use those techniques to forecast file system sizes as well.

Subject: Help with Storage Capacity
We have a database server with one of the largest and fastest growing customer. Here is the current size of the database server.
What process do you have to decide when to add more storage? Do you have to request for more storage or does the sysadmin monitors the server and add accordingly?
I am trying to understand what processes are out there. Thanks.
