Changing Dirty Threshold Flush Start Setting 
As part of the System Cache Policy settings, a user is able to change the 
maximum percentage of the total onboard SuperTrak66 memory that can be 
occupied by data that has not yet been written to disk (i.e. "dirty" data) before it is 
flushed from memory.  
 
1)   Double-click the IOPx icon in Tree View.  
2)   In the Information View (see Figure 65 on p. 84), enter a new number to change 
the maximum percentage of cache memory that can be occupied by "dirty" 
data before being cleared automatically. 
3)   Click “Commit” to enable the change or continue with other selections. 
Changing Dirty Threshold Flush Stop Setting 
As part of the System Cache Policy settings, a user is able to set the minimum 
percentage of memory allowed by SuperTrak66 for data that has not yet been 
written to disk (i.e. "dirty" data). This will stop SuperTrak66 from cleansing "dirty" 
data from memory beyond this percentage point. 
 
1)   Double-click the IOPx icon in Tree View.  
2)   In the Information View (see Figure 65 on p. 84), enter a new number to change 
the minimum percentage level of cache memory that can be occupied by 
"dirty" data and stop flushing automatically. 
3)   Click “Commit” to enable the change or continue with other selections.
