Instantaneous +12V current peaks will exceed these values. N (number of drives tested) = 6, 35 Degrees C ambient. 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 7. 2. 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 60 seconds to a random location within the band from three-quarters to maximum track.

G 146GB models in 3 Gbit operation Typical power dissipation under idle conditions in 3Gb operation is 3. 43 watts (11. 70 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 19). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3. 4123. Figure 21. 146GB (at 3 Gbit) DC current and power vs. input/output operations per second Savvio 10K. 3 SAS Product Manual, Rev. G 29 146GB models in 6 Gbit operation Typical power dissipation under idle conditions in 6Gb operation is 3. 48 watts (11. 87 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 19). Locate the typical I/O rate for a drive in your system on the horizontal axis and read the corresponding +5 volt current, +12 volt current, and total watts on the vertical axis. To calculate BTUs per hour, multiply watts by 3. 4123. Figure 22. 146GB (at 6 Gbit) DC current and power vs. input/output operations per second 7. 4 Environmental limits Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. [. . . ] Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot plugging. 12. 5 Signal characteristics This section describes the electrical signal characteristics of the drive's input and output signals.
