Instantaneous +12V current peaks will exceed these values. N (number of drives tested) = 6, 35 Degrees C ambient. Savvio 10K. 4 SAS Product Manual, Rev. A 23 [2] [3] [4] [5] [6] [7] For +12 V, a ­10% tolerance is allowed during initial spindle start but must return to ±5% before reaching 9, 936 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. 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. Operating condition is defined as random 8 block reads. During idle, the drive heads are relocated every 30 seconds to a random location within the band from three-quarters to maximum track. 24 Savvio 10K. 4 SAS Product Manual, Rev. A General DC power requirement notes. Minimum current loading for each supply voltage is not less than 1. 7% of the maximum operating current shown. The +5V and +12V supplies should employ separate ground returns. 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. Savvio 10K. 4 SAS Product Manual, Rev.
