1.3.3 Firmware (FW) and RAIDWatch GUI
Firmware: The firmware is pre-installed software used to configure the
subsystem. The latest firmware functionalities include Task Scheduler,

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 internals. For more information, please refer to the Generic
Manual in the product CD.
