3.7.6.1 Stagger Power On
In a PC system with only one or two drives, the power can sup-
ply enough power to spin up both drives simultaneously. But in
systems with more than two drives, the startup current from
spinning up the drives all at once can overload the power sup-
ply, causing damage to the power supply, disk drives and other
system components. This damage can be avoided by allowing
the host to stagger the spin-up of the drives. The SAS/SATA
drives have support stagger spin-up capabilities to boost reli-
ability. Stagger spin-up is a very useful feature for managing
multiple disk drives in a storage subsystem. It gives the host
the ability to spin up the disk drives sequentially or in groups,
allowing the drives to come ready at the optimum time without
straining the system power supply. Staggering 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 conditions.
Areca RAID controller has included the option for customer to
select the disk drives sequentially stagger power up value. The
values can be selected from 0.4s to 6s per step which powers up
one drive.
