7.1.1PowerChoice reporting methods

PowerChoiceTM provides these reporting methods for tracking purposes:

Request Sense command reports

Current power condition

Method of entry

Note. Processing the Request Sense command does not impact the drive’s power save state.

Mode Sense command reports (mode page 0x1A)

Idle conditions enabled / disabled

Idle condition timer values (100ms increments) (default, saved, current, changeable)

Power Condition Vital Product Data (VPD) Page (VPD page 0x8A)

Supported power conditions

Typical recovery time from power conditions (1ms increments)

Start/Stop Cycle Counter Log Page reports (log page 0x0E)

• Specified and accumulated Start/Stops and Load/Unload cycles

Power Condition Transitions Log Page reports (log page 0x1A, subpage 0x00)

• Accumulated transitions to Active, Idle_A, Idle_B, Idle_C, Standby_Y, Standby_Z

7.2AC power requirements

None.

7.3DC power requirements

The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector.

The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply.
