• Smart Polling Interval
Besides the scheduled volume check, user can define the Smart
Pulling Interval to pull the SMART status of each disk. The de-
fault 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 “ Smart Polling Interval” too frequent.
What to use is up to the users to decide based on their applica-
tions and experimental results.
6.8.2 Advanced Configuration
To set the RAID system function, move the cursor to the main
menu and click the “Advanced Configuration” link. The “Advanced
Configuration” menu will show all items, and then select the de-
sired function.
• TLER Setting
TLER (time-limited error recovery) functions provide support for
WD Caviar RE (RAID) series disks. This is a new option from WD
to support RAID features that were traditionally missing from
standard desktop drives. TLER is a method of signaling the sys-
tem RAID controller in the event that an error recovery process
is taking longer than time-out specifications allow. This prevents
the RAID controller from dropping the drive from the array dur-
ing this period. Default value is manufacture setting. You can
select between 5, 6 and 7 second. This feature is used to setup
the HDD internal timeout value.
