Write Same Support
Drives that support the Write Same feature (SCT) can write to multiple drive sectors at once,
improving initialization time. To take advantage of this feature, all the drives in the unit must
support Write Same. User can set the “SAS And SATA”, “SAS Only”, “SATA Only” or “Disabled”
for the controller initialization.
3.7.5.15.
Capacity Truncation
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 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 Disabled.
•
Multiples Of 10G: If you have 120 GB drives from different vendors; chances are that
the capacity varies slightly. For example, one drive might be 123.5 GB, and the other
120 GB. “Multiples Of 10G” truncates the number under tens. This makes the same
capacity for both of these drives so that one could replace the other.
