Configuring Power Management for a Controller
The power management options for a controller affect all logical drives on that controller. You
can choose a "stay awake" period during which disk drives on the controller always operate at
their peak spin rate. You can also set the spin-up limits for the controller—the maximum
number of drives the controller may spin up at the same time.
Note:
The time you set for the stay awake period is relative to your local system time and time
zone. To set the time zone for power management, you must use the controller BIOS utility. The
time zone does not adjust automatically for daylight savings time. To compensate for the time
difference, you must adjust the stay awake period manually, either in the BIOS or with Adaptec
Storage Manager. For more information, see the Adaptec RAID Controller Installation and User's
Guide.
To set the stay awake period for disk drives:
1
In the Enterprise View, select a controller.
2
In the menu bar, select Actions, click Power settings, then click Set stay awake settings.
