their rotation speed to generate more cooling air to extract the heat generated by the hard drives.

2.4	Subsystem Monitoring
	The RAID subsystem comes with a number of different monitoring methods that provide you
	with continual updates on the status of the system and individual components. The following
	monitoring features are included in the subsystem.
2.4.1	I2C bus
	The following elements are interfaced to the RAID controller over a non-user-serviceable I2C
	bus:

•

•

Cooling modules

Temperature sensors (for detecting the temperature of the backplane board and control- ler board)

2.4.2	LED Indicators
	The following active components come with LEDs to indicate the status of the individual com-
	ponent:
	RAID controller (9 LEDs)
	BBU module (1 LED)
	Cooling modules (1 LED on each module)
	PSU modules (1 LED on each module)
	Drive trays (2 LEDs on each tray)

2.4.3	Firmware (FW)
	The firmware is pre-installed software used to configure the subsystem. The latest firmware
	functionalities include Task Scheduler, Intelligent Drive Handling, and Media Scan. Media
	Scan handles low quality drives in both the degraded mode and during the rebuild process.
	Maintenance tasks will then be performed on an entire array or specific hard drives. Various
	options are user-configurable such as priority, start time, and execution intervals.

2.4.4Audible Alarms

The RAID subsystem comes with audible alarms that are triggered when certain active compo- nents fail or when pre-configured (RAID controller or subsystem) thresholds are exceeded. Whenever you hear an audible alarm from the RAID subsystem, it is imperative that you deter- mine the cause and rectify the problem immediately.
