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 HPE 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.
Fault Tolerance
Keeps data available and server running while a failed drive is being replaced; several fault tolerance
