Fibre to SAS/SATA Disk Array
122 User Manual
Time to HDD Low RPM Mode: (MAID Level 2)
This option enables the Disk Array to place idle HDDs of a Raid Set in Low RPM Mode,
where drives’ heads are unloaded and drive platters speed is reduced to around 4000
RPM. The power consumption of the Idle HDD saving is from 35% to 45%. Recovery
time is 15 seconds.
Options are: Disabled, 10, 20, 30, 40, 50, and 60 (Minutes).
Time to Spin Down Idle HDD: (MAID Level 3)
This option enables the Disk Array to spin down HDDs of a Raid Set after they become
idle after a preset period of time. In this level, the drives stop spinning and go into
sleep mode. The power consumption of the Idle HDD saving is from 60% to 70%.
Recovery time is 30 to 45 seconds.
Options are: Disabled, 1 (For Test), 3, 5, 10, 15, 20, 30, 40, and 60 (Minutes).
Time To Wait HDD Spin Up
This option allows user to set the host system waiting time for HDD spin up. The
values can be selected from 7 to 120 seconds.
NOTE: To verify if the disk drive you use supports MAID or APM,
select “RaidSet Hierarchy” and click the disk drive (E# Slot#) link.
Check in the Device Information screen if the Disk APM Support
shows “Yes”.
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 power-up and to allow the controller
to sequence the spinup of devices. It is mainly for server/workstation environments
operating in multiple-drive configurations.
Delay for Phy to Stable
This function is used to increases the availability of the HDD unpredictable behavior.
Delay timing can be set from 10 to 50 seconds, indicating the time that the controller
waits, from the startup of the system until the hard drive is being detected. The
default is
Disabled.
