AC power requirements 6. 3 DC power requirements The voltage and current requirements for a single drive are shown below. 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.

For +12 V, a ­10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 7, 200 RPM. The ±5% must be maintained after the drive signifies that its power-up sequence has been completed and that the drive is able to accept selection by the host initiator. 22 Constellation SAS Product Manual, Rev. This condition occurs after OOB and Speed Negotiation completes but before the drive has received the Notify Spinup primitive. See paragraph 6. 3. 1, "Conducted noise immunity. " Specified voltage tolerance includes ripple, noise, and transient response. During idle, the drive heads are relocated every 60 seconds to a random location within the band from three-quarters to maximum track. General DC power requirement notes. Minimum current loading for each supply voltage is not less than 1. 7% of the maximum operating current shown. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be available to each device. Parameters, other than spindle start, are measured after a 10-minute warm up. 6. 3. 1 Conducted noise immunity Noise is specified as a periodic and random distribution of frequencies covering a band from DC to 10 MHz. Maximum allowed noise values given below are peak-to-peak measurements and apply at the drive power connector. +5v +12v = = 250 mV pp from 100 Hz to 20 MHz. 250 mV pp from 20 KHz to 5 MHz. 6. 3. 2 Power sequencing The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down. Constellation SAS Product Manual, Rev.
