Specify period for Replacement Effect Prediction
On the [Graph Indicating Replacement Effect Prediction] dialog, specify a period for Replacement Effect
Prediction of logical disks. Specifying a period when a bottleneck occurred makes it easier to know the effect of
replacing applicable logical disks. Specify a start date and end date, and then click the [Show Graph] button.

Download performance optimization log file containing Busy Ratios
Clicking [Show Graph] button on the [Graph Indicating Replacement Effect Prediction] dialog displays the
Download Selection dialog.
Figure 6-17 shows an example of Download Selection dialog. Table 6-16 describes the areas on the Download
Selection dialog.

Show graph after downloading insufficient data
Show graph using data already downloaded
Selecting [Show graph after downloading insufficient data] and clicking [OK] button downloads the performance
optimization log files accumulated on the iSM server onto the iSM client, and the optimization log files stored in
a folder to store data is updated into a latest file. For the folder to store data, refer to 6.2.3 "Setting Folder to
Store Data".
Selecting [Show graph using data already downloaded] and clicking [OK] button results in estimating
replacement effect without downloading performance optimization log files form the iSM server. In this case,
replacement effect is estimated for a log accumulation period of the optimization log files that have already been
downloaded.
If the optimization log files of the specified period have already been downloaded for estimating replacement
effect, the Confirmation of Overwriting dialog is displayed. Figure 6-18 shows the Confirmation of Overwriting
dialog.
