Pre-Failure Warranty
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) was first developed by HP which
detects possible hard disk failure before it occurs, allowing replacement of the component before
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.
Environment Tracking for External Storage System: Monitors fan speed and cabinet temperature of
StorageWorks Modular Smart Array Enclosures.
Keeps data available and server running while a failed drive is being replaced; several fault tolerance
configurations are supported including:
Distributed Data Guarding (RAID 5): This allocates parity data across multiple drives and allows
simultaneous write operations. It is recommended for up to 14 hard drives.
RAID5 is available on the SA E500 only if the battery kit option is used
Drive Mirroring (RAID 1, 1+0): 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.
Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
Recovery ROM: This new feature provides a unique redundancy feature that protects from a ROM
image corruption. A new version of firmware can be flashed to the ROM while the controller
maintains the last known working version of firmware. If the firmware becomes corrupt, the
controller will revert back to the previous version of firmware and continue operating. This reduces
the risk of flashing firmware to the controller.
On-Line Spares: There is no limit to the number of spare drives that can be installed prior to drive
failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed
automatically.
DRAM ECC corrects against single bit data and address corruption.
