The following features offer detection of possible failures before they occur, allowing preventive
action to be taken:

detects possible hard disk failure before it occurs, allowing replacement of the hard drive
before a real failure occurs.
Drive Parameter Tracking monitors drive operational parameters, predicting failure and
notifying the administrator.
Dynamic Sector Repairing continually performs background surface scans on the hard disk
drives during inactive periods and automatically remaps bad sectors, ensuring data integrity.
Smart Array Cache Tracking monitors integrity of controller cache, allowing pre-failure
preventative maintenance.
