• HDD SMART Status Polling
An external RAID enclosure has the hardware monitor in the
dedicated backplane that can report HDD temperature status
to the controller. However, PCI type controllers do not use
backplanes if the drives are internal to the main server chassis.
The type of enclosure cannot report the HDD temperature to the
controller. For this reason, "HDD SMART Status Polling" function
was added to enable scanning of the HDD temperature function.
It is necessary to enable “HDD SMART Status Polling” function
before SMART information is accessible. This function is disabled
by default.
The following screen shot shows how to change the setting to
enable the polling function.
• Auto Activate Incomplete Raid
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 SATA RAID controller is powered on, the user can set
the “Auto Activate Incomplete Raid” option to enable. The RAID
state will change to “Degraded Mode” while it powers on.
•
Disk Write Cache Mode
A user can set the “Disk Write Cache Mode”: Auto, Enabled, or
Disabled.
•
Disk Capacity Truncation Mode
SATA RAID controller 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
conguration: “Multiples Of 10G”, “Multiples Of 1G”, and “No
Truncation”.
