Note that you need to restart HDD Guardian when you change a setting on this setup page.
From here you can see all RAID controllers that are tested and working with HDD Guardian. You can also add your controller (if is missing), edit an entry or delete a controller from the list if for some cases is in conflict with another one.
From this section you can set for SATA controller the total amount of connected devices, and for SAS controller, for each enclosure, the total amount of connected devices.
By default HDD Guardian provides a value of 4 for each channel, but is possible to increase or decrease this value.
