under Gen3 slot. You must restart the computer twice for the PCIE Gen3 setting to
take effect.
4.8.1.17 SES2 H/W Monitor
The options are: “Enabled”, “Disabled”.
4.8.1.18 Disk Capacity Truncation Mode
The RAID subsystem uses 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 “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 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 example, one drive might be 123.5 GB, and the other
123.4 GB. Multiples Of 1G truncates the fractional part. This makes capacity for both
of these drives so that one could replace the other.
No Truncation: It does not truncate the capacity.
4.8.1.19 Smart Option For HDD
This option is used to increases the reliability of SSDs/HDDs by automatically
copying data from a drive with potential to fail to a designated hot spare or newly
inserted drive. The options are: “Failed The Drive”, “Failed The Drive If Hot Spare
Exist”, and “Alert Only”.
Failed The Drive : controllers kill off the SMART fail drive immediately.
Failed The Drive If Hot Spare Exist :
controllers kill off the SMART fail disk if hot spare dive is existed.
Alert Only : it will trigger alert when there happens a SMART fail drive.
4.8.1.20 Smart Polling Interval
Besides the scheduled volume check, user can define the Smart Pulling Interval to
pull the SMART status of each disk. The default is “on demand”.
User can schedule every certain period of time interval to pull the SMART status of
each disk. When SMART pulling is executed, disk activity will be temporally halted
until the SMART parameter reading is finished. That is why you don’t want to set the
Interval too frequent. What to use is up to the users to decide based on their
applications and experiment results.
