Chapter 5: Configuration Parameters

Drive-side Parameters 5-23

11. Power Saving:

This feature supplements the disk spin-down function, and

supports power-saving on specific logical drives or un-used disk

disks with an idle state and the 2-stage power-down settings.

Advantages: see the power saving features below.

Applicable Disk Drives:

Logical drives and non-member disks [including spare drives and

un-used drives (new or formatted drives)]. The power-saving

policy set to an individual logical drive (from the View and Edit

Logical Drive menu) has priority over the general Drive-side

Parameter setting.

Power-saving Levels:

NOTE: HDD vendors may have different definitions for the

idle state. Most vendors ramp-load or park the hard disk

actuator arm, while not all vendors reduce the rotation speed.

for a configurable period of time before entering the Level 2

spin-down state.

2-1. Disable,

2-2. Level 1 only,

2-3. Level 1 and then Level 2,

2-4. Level 2 only. (Level 2 is equivalent to legacy spin-down)

3. The Factory defaults is “Disabled” for all drives. The default

for logical drives is also Disabled.

4. The preset waiting period before entering the power-saving

state:

4-1. Level 1: 5 minutes
