Fault Prevention The following features offer detection of possible failures before they occur, allowing preventive action to
be taken:
S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at HP 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.
