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.
Fault Tolerance
Keeps data available and server running while a failed drive is being replaced; several fault tolerance
configurations are supported including:
RAID 6 with ADG
(Advanced Data Guarding): This is the highest level of fault tolerance. It allocates
two sets of parity data across drives and allows simultaneous write operations. This level of fault
tolerance can withstand two simultaneous drive failures without downtime or data loss.
RAID 6+0
: Supported with min of 8 drives, but would have 4 available. Target benefit is to split RAID
across the external boxes
NOTE:
RAID 6, 6+0 can be enabled with either
Minimum of 256 MB cache with Battery and Smart Array Advanced Pack License key option
upgrades
Minimum of 512 MB BBWC/FBWC and Smart Array Advanced Pack License key option
upgrades
RAID 5
(Distributed Data Guarding): This allocates one set of parity data across drives and allows
simultaneous write operations. This level of fault tolerance can withstand a single drive failure
without downtime or data loss.
RAID5 is available on the SA P410/P410i with a minimum of 256MB cache and battery
RAID 5+0
: This is a RAID 0 array striped across 5 elements. Combines the straight block-level
striping of RAID 0 with the distributed parity of RAID 5.
RAID 1, 1+0
(Drive Mirroring): This allocates half of the drive array to data and the other half to
mirrored data, providing two copies of every file. It is a high-performance RAID.
