• Global Online Spare
• Pre-Failure Warranty

• 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 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.

• 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 is available only with the minimum of 256MB, Battery Kit, 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.
  NOTE: RAID 5 is available with the 256MB & Battery Kit upgrade option.
• 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.

• 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.
• Battery-backed write cache upgrade provides for up to three days of battery power for data cache retention. The data backup duration could be extended anytime the server's auxiliary power is available during system power down.

• GUI based configuration, management and diagnostic software tools
• Common data format between generations of products
