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

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 I

C bus

The following elements are interfaced to the RAID controller over a non-user-serviceable I

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.

2.4.4 Audible 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.
