5.2.4 Drive Spindown Idle Delay Period
Figure 5 - 15: Selecting Drive Spindown Idle Delay Period
This is power saving feature which allows hard drive motor to spin
down after a configurable period of time with no I/O requests
directed to the hard drives.
The drive spin down command is designed for usage on disk-to-
disk (D2D) backup system. In normal case, the RAID system serves
as I/O interface between hosts and drives. On disk-to-disk (D2D)
backup system, the I/Os only occur when the backup command is
valid. Without backup requirements, the spin down command can
make drives enter an idle state hence reduce the power
consumption of drives.
User can setup an idle period for the drives. Drives will
automatically spin down while there is no read/write command to
drives within the idle period. Then if any I/O command is issued,
such as disk backup, the drives will wake up and serve the I/O
requirement.
Choose “Drive Spindown Idle Delay Period,” then press [ENTER].
A list of selections will appear. Move the cursor bar to a selection,
then press [ENTER]. Choose Yes in the dialog box that follows to
confirm the setting.
