[. . . ] 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. 2. 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. 2. 2 Power sequencing The drive does not require power sequencing. The drive protects against inadvertent writing during power-up and down. Savvio 10K. 3 SAS Product Manual, Rev.

D Figure 17. Current profiles for 146GB models Note: All times and currents are typical. See Tables 2 and 3 for maximum current requirements. Savvio 10K. 3 SAS Product Manual, Rev. D 25 6. 3 Power dissipation 300 GB models in 3 Gbit operation Typical power dissipation under idle conditions in 3Gb operation is 3. 79 watts (12. 93 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 18). 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 18. 300GB (at 3 Gbit) DC current and power vs. input/output operations per second 26 Savvio 10K. 3 SAS Product Manual, Rev. D 300GB models in 6 Gbit operation Typical power dissipation under idle conditions in 6Gb operation is 3. 82 watts (13. 03 BTUs per hour). To obtain operating power for typical random read operations, refer to the following I/O rate curve (see Figure 18). 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 19. 300GB (at 6 Gbit) DC current and power vs. input/output operations per second Savvio 10K. 3 SAS Product Manual, Rev.
