Performance	HP's High Performance Architecture sets new boundaries of industry performance expectations!
	Wide Ultra320 SCSI (320 MB/s bandwidth) per channel High-performance 64-bit architecture 64-bit, 133-MHz PCI-X bus (1033 MB/s bandwidth)

Capacity	Smart Array 641	Given the internal server storage need for rapid capacity expansion, the SA-641 offers:
		Single SCSI channel support up to 6 internal disk drives Up to 880.8GB of storage per PCI slot
	Smart Array 642	Given the internal server storage need for rapid capacity expansion, the SA-642 offers:
		Dual SCSI channels support up to 20 (6 internal, 14 external) disk drives Up to 2.9 TB of storage per PCI slot

Availability	Provides increased server uptime by providing advanced storage functionality:
	Online RAID Level Migration (between any RAID level) Online Capacity Expansion Logical Drive Capacity Extension Global Online Spare Pre-Failure Warranty

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 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	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. 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	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: Up to two 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.
	NOTE: On-Line Spares can only be used with RAID level 1, 1+0, and 5.

Ease of Use	Consistency and Upgradability make the Smart Array family unique in the industry:
	GUI based configuration, management and diagnostic software tools Common data format between generations of products Data migration between servers and external storage enclosures
