How to Use/Install IBM Optim Data Growth Solution

Hello Everyone, I have heard and read about the IBM Optim tools that can be used with IDS 11. So i am quiet interested in using the IBM Data Growth Solution with our existing database servers running on IDS 11, because the sizes of the database is growing fast, so i want to evaluate that how this tool could help me overcome the fast growth issue to sustain/improve the performance. But i dont know how to install/configure the IBM Data Growth tool with IDS. can anyone guide me or help me in installation. I will be waiting for your response. Thanks. Omer Saeed Khan
