the optimum time without straining the system power supply.
The staggered drive spin-up in a multiple drive environment
also avoids the extra cost of a power supply designed to meet
short-term startup power demand as well as steady state con-
ditions.
With this option it gives the RAID storage the ability to spin
up the disk drives sequentially staggered power up value. The
values can be selected from 0.4 to 6 seconds per step which
powers up one drive.
• Time To Hdd Low Power Idle
This option delivers lower power consumption by automati-
cally unloading recording heads during the setting idle time.
The values can be selected “Disabled” or within the range 2 to
7 minutes.
• Time To Hdd Low RPM Mode
This function can automatically spin disks at lower RPM if
there have not been used during the setting idle time. The
values can be selected “Disabled” or within the range 10 to 60
minutes.
• Time To Spin Down Idle HDD
This function can automatically spin down the drive if it hasn’t
been accessed for a certain amount of time. This value is used
by the drive to determine how long to wait (with no disk activ-
ity, before turning off the spindle motor to save power). The
values can be selected “Disabled” or within the range 1 to 60
minutes.
• SATA Power Up In Standby
SATA Power Up In Standby (power management 2 mode,
PM2) is a SATA disk drive configuration which prevents the
drive from automatic spinup when power is applied. “Enabled”
option allows the drive to be powered-up into the Standby
power management state to minimize inrush current at pow -
er-up and to allow the controller to sequence the spinup of de-
vices. It is mainly for server/workstation environments operat-
ing in multiple-drive configurations.
