Green Flash Drive Activity
The hard drives directly control the activity LED functionality. This causes the LED to
function differently between SAS and SATA drives.
Note: The drive status LED may also be set by the add-in SAS RAID controller or by RAID
management software to represent different RAID array states. Refer to the RAID controller or
software documentation.
