When some of the disk drives are removed in power off state
or boot up stage, the RAID set state will change to “Incomplete
State”. But if a user wants to automatically continue to work
while the SAS RAID controller is powered on, then user can set
the “Auto Activate Raid Set” option to “Enabled”. The RAID state
will change to “Degraded Mode” while it powers on.
3.7.5.11 Capacity Truncation
Areca RAID controllers use drive truncation so that drives from
different vendors are more likely to be usable as spares for one
another. Drive truncation slightly decreases the usable capac-
ity of a drive that is used in redundant units. The controller
provides three truncation modes in the system conguration:
Multiples Of 10G, Multiples Of 1G and Disabled.
Multiples Of 10G: If you have 120 GB drives from different
vendors; chances are that the capacity varies slightly. For exam-
ple, one drive might be 123.5 GB, and the other 120 GB. “Mul-
tiples Of 10G” truncates the number under tens. This makes the
same capacity for both of these drives so that one could replace
the other.
Multiples Of 1G: If you have 123 GB drives from different
vendors; chances are that the capacity varies slightly. For ex-
ample, one drive might be 123.5 GB, and the other 123.4 GB.
“Multiples Of 1G” truncates the fractional part. This makes the
