5. Select one of the following options from View results to choose the format you want to view the

6. Click Start to run the performance modeling tool.
NOTE: Depending on the cache capacity and workload, it may take about 10 to 20 hours to
fully populate the cache. There is valid information even after a run of a few minutes, but it
takes a number of hours to obtain the most accurate predictions.
NOTE: While the performance modeling tool is running, a progress bar is displayed in the main
area of the window. You can close or minimize the window and the performance modeling
continues to run. You can even close the MD Storage Manager and the performance modeling
session continues to run.
NOTE: At the beginning of the ramp up time, the performance may be slower than if SSD cache
was never enabled.
7. To save the results of a performance modeling session, click Save As and save the data to a .csv file.
