Pulsar.2 SAS Product Manual, Rev. B
7.0
Physical/electrical specifications
This section provides information relating to the physical and electrical characteristics of the drive.
7.1
Power specifications
The drive receives DC power (+5V and +12V) through the standard SAS interface.
7.1.1
Power consumption
Power requirements for the drives are listed in the tables beginning on page
26. Typical power measurements
are based on an average of drives tested, under nominal conditions, using +5V and +12V input voltage at 60°C
ambient temperature.
•
Startup power
Startup power is measured from the time of power-on to the time that the drive reaches operating condition
and can process media access commands.
•
Peak operating mode
During peak operating mode, the drive is tested in various read and write access patterns to simulate the
worst-case power consumption.
•
Idle mode power
Idle mode power is measured with the drive powered up and ready for media access commands, with no
media access commands having been received from the host.
7.2
AC power requirements
None.
