Support for SMART
Drive failure detection
Drive rebuild using hot spares
Parity generation and checking
A. The Self Monitoring Analysis and Reporting Technology (SMART) detects up to 70 percent of
all predictable drive failures. In addition, SMART monitors the internal performance of all
motors, heads, and drive electronics.

Electrical Characteristics

This subsection provides the power supply requirements for the 12Gb/s Intel
Controllers.
Power Supply Requirements for the Intel
All power is supplied to the Intel
rails and the 12V rail. On-board switching regulator circuitry operating from the 3.3V
rails and the 12V rail provides the necessary voltages. The following states determine the
typical current consumption of the controller:
•
State 1: During a hard reset
•
State 2: During a drive stress test
•
State 3: While sitting idle at the DOS prompt
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± 9
percent (from PCI edge connector only). The following table lists the power for the RAID
controllers at peak and normal status.

On-Normal/Typical
Note: The charging circuitry for the battery pack on the optional BBU battery-backed daughter
card uses +12V. If the BBU daughter card is mounted, the following power consumption
figures apply:
