Appendix C: Using the Adaptec RAID Configuration Utility ● 99 Power Management Settings Note: When power management is disabled, no related options will be displayed. Note: Make sure the operating system driver supports power management. Note: Default settings are shown in bold type. Option Description Power Management Settings When enabled, switches the system to low power state, based on the specified settings. Time Zone The time zone of the place in which the system is located. Time specific power management settings are implemented based on the set time zone. By default, it is set to 00:00. The valid range for the time zone settings is -12:00 to +12:00. Stay Awake Start The time from which the system should operate in the full power mode, irrespective of other power management settings, daily. By default it is set to 00:00. The valid range is 00:00 to 23:59. Stay Awake End The time until which the system should operate in the full power mode, irrespective of other power management settings, daily. By default it is set to 00:00. The valid range is 00:00 to 23:59. Spin Up Limit (Internal) The number of internal drives to be spun up at any given moment. By default it is set to 0. In the default setting, all the internal drives will spin up. Spin Up Limit (External) The number of external drives to be spun up at any given moment. By default it is set to 0. In the default setting, all the external drives will spin up. PHY Settings Note: For 3-series controllers, these settings are read-only and non-editable. These settings are not available on the Adaptec RAID 31205 and Adaptec RAID 31605 controllers. Option Description PHY Rate The data transfer rate between the controller and devices. The default setting is Auto, which allows the SAS card to adjust the data transfer rate, as needed. For low-port 5-series RAID controllers (5085, 5405), you can set the PHY rate to 1.5Gb/second or 3.0Gb/second (the maximum rate). CRC Checking When enabled, determines whether the controller verifies the accuracy of data transfer on the serial bus. Default setting is Yes (enabled). Set to No (disabled) only if the controller is connected to a device that does not support CRC Checking. SAS Address In a situation where you want each phy on a controller to be in a different SAS domain, this setting specifies a unique world-wide name for each phy. Default is 0. Note: This setting is for SAS address conflict resolution only and should otherwise remain at its default value. Formatting and Verifying Disk Drives You can use the disk utilities to low-level format or verify your disk drives. (New disk drives are low-level formatted at the factory and do not need to be low-level formatted again.) ! Caution: Before you format a disk drive, back up all data. Formatting destroys all data on a disk drive.

0
. In the default setting, all the internal drives will
spin up.

When enabled, determines whether the controller verifies the accuracy of data
transfer on the serial bus. Default setting is
Yes
(enabled). Set to No (disabled)
only

SAS Address
In a situation where you want each phy on a controller to be in a different SAS
