• Advanced Data Guarding (RAID ADG) offers breakthrough level of fault protection of RAID volumes up to 2TB and a total of 56 disk drive in a single RAID volume. RAID ADG provides fault protection greater than RAID 1 or RAID 5 and only consume the capacity of 2 disk drives for distributed parity data. RAID ADG protects against any 2 disk drive failures. This higher level of protection is ideal to protect large logical volumes and with high capacity disk drives where a failed drive rebuild time may be significant.
  NOTE: RAID ADG is a standard feature of SA-5304 and available as an option to other models. RAID ADG requires a minimum of 64-MB battery-backed cache.
• Modular, easy-to-upgrade design lets you optimize performance and increase capacity, as needed, from two to four channels and with 32-MB, 64-MB, 128-MB, or 256-MB battery-backed cache.
  128-MB or 256-MB battery-backed cache.
• High-performance, Fifth generation architecture offers the new hardware RAID engine, and a new performance memory architecture for increased performance over previous controllers.
• Recovery ROM protects against a ROM failure or corruption.
• Ultra3 SCSI technology delivers high performance and data bandwidth up to 160 MB/s bandwidth per channel.
• Up to 4 channels provides the highest storage capacity per PCI slot in the industry.
• Mix-and-match LVD SCSI compatibility protects your investments and lets you deploy drives as needed.
• Battery-backed Cache protects cached data in the event of a power outage, server failure or controller failure, and redundant, replaceable batteries take that protection even further. Maximum cache configuration is 256-MB of battery-backed cache.
• 64-bit, 66-MHz PCI interface boosts bandwidth up to a 533 MB/s total transfer rate.
• 64-bit memory addressing supports servers with greater than 4 GB of memory.
• Online Management Features: Online Capacity Expansion, Online RAID Level Migration, Online Stripe Size Migration, Multiple Online Spares (Global), User Selectable Read/Write cache, User Selectable Expand and Rebuild Priority
• SAN Access, the industry's first integrated SCSI controller and Fibre Channel SAN adapter offers centralized, consolidated backup solutions and incremental SAN based primary storage for groups of 5-10 servers driving Direct Attach Storage (SCSI) with Smart Array 5302 Controllers.

• Data Compatibility - among all models of Smart Array controllers allows simple and easy upgrades any time needs for higher performance, capacity, and availability increase. Even successive generations of Smart Array controllers understand the data format of other Smart Array Controllers.
• Consistent Configuration and Management Tools - all Smart Array products utilize a standard set of management and utility software. These tools minimize Total Cost of Ownership (TCO) by reducing training requirements and technical expertise necessary to install and maintain the ProLiant server storage.
• Universal Hard Drive - form factor is for use across multiple ProLiant servers, disk enclosures and storage systems. With compatibility across many enterprise platforms, you are free to deploy and re-deploy these drives to quickly deliver increased storage capacity, migrate data between systems, and easily manage spare drives.
• Pre-Failure Warranty - means Insight Manager™ not only reports when a drive is going to fail but allows replacement of failing drives prior to actual failure. For complete details, consult the HP Support Centre or refer to your ProLiant Server documentation.

Availability

• Online RAID Level Migration (between any RAID level)

• Global Online Spare
• Pre-Failure Warranty

Fault Prevention

• S.M.A.R.T.: Self Monitoring Analysis and Reporting Technology first developed at Compaq 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 ProLiant Storage System and newer HP storage enclosures.

Fault Tolerance

• Advanced Data Guarding (RAID ADG): 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. It is available standard with SA-5304 and as an option to other models. Requires a minimum of 64-MB battery-backed cache.
• 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.
• 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.

Fault Recovery

• Recovery ROM: provides a unique redundancy feature that protects from a ROM failure. A new version of firmware can be flashed to the ROM while the controller maintains the last know 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: Up to four spare drives can be installed prior to drive failure. If a failure occurs, recovery begins with an On-Line Spare and data is reconstructed automatically.
• ECC-Protected Cache Memory: Removable, battery-backed cache memory protects data, up to four days (three days with 256-MB Module), in the event of power failure, server hardware failure or controller failure. In addition, HP provides an exclusive design that includes redundant and replaceable batteries for greater cache protection.
  - 256-MB, 128-MB and 64-MB Cache modules also feature Chip Recovery, protecting the cache memory from a single chip failure and multi-bit errors from any single memory chip.

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

All Smart Array products share a common set of configuration, management and diagnostic tools, including Array Configuration Utility XE (ACU-XE), Array Configuration Utility (ACU), Array Diagnostic Utility (ADU), and Insight Manager. This software consistency of tools reduces the cost of training for each successive generation of product and takes much of the guesswork out of troubleshooting field problems. These tools lower the total cost of ownership by reducing training and technical expertise necessary to install and maintain the HP server storage.
