5.5.5.10 Disk Capacity Truncation Mode
ARECA RAID controllers use drive truncation so that drives from
differing vendors are more likely to be able to be used as spares
for each other. Drive truncation slightly decreases the usable
capacity of a drive that is used in redundant units.
The controller provides three truncation modes in the system
configuration:
Multiples Of 10G
,
Multiples Of 1G
, and
No
Truncation
.
Multiples Of 10G:
If you have 120 GB drives from differ-
ent vendors; chances are that the capacity varies slightly. For
example, one drive might be 123.5 GB, and the other 120 GB.
Areca drive Truncation mode
Multiples Of 10G
uses 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 ven-
dors; chances are that the capacity varies slightly. For example,
one drive might be 123.5 GB, and the other 123.4 GB. Areca
drive Truncation mode
Multiples Of 1G
uses the same capacity
for both of these drives so that one could replace the other.
No Truncation:
It does not truncate the capacity.
