Each function is executed
by a two-step procedure: Click to select a desired value from the pull-down
menu and click the Apply button for the configuration to take
effect. Some configuration changes may only take effect after resetting the
subsystem.
See below for configuration with Drive-Side Parameters, click here
for Host-Side and Disk-Array Parameters.
- Drive-Side Parameters -
Disk Access Delay Time(Sec): Sets the delay time before the
subsystem tries to access the hard
drives after power-on. Default is 15 seconds.
Drive Check Period(Sec): is the time interval for the controller
to check all disk drives that were on the drive busses at controller startup.
The default value is “Disabled.” “Disabled” means that
if a drive is removed from the bus, the controller will not be able to know
– so long as no host accesses that drive. Changing the checking time to
any other value allows the controller to check at the selected time interval
for all array hard drives. If any drive is then removed, the controller will
be able to know even if no host accesses that drive.
Auto-assign Global Spare Drive: Enable or disable the auto-assign global spare drive functionality.
S.M.A.R.T.: This allows you to configure SMART-related functionality. SMART is short for Self-Monitoring, Analysis and Reporting Technology. Click here for more information about SMART.
Drive Motor Spin Up: Selected when hard drives need to "Spin-up by drive command". By default, all hard drives will start spinning up when powered-on. Also refer to the documentation that came with your hard drives.
Drive Delayed Write: Enable/disable the drive write cache. (Note: This function is only applicable on RAID subsystems running Firmware 3.47 or above version with SATA HDD configured.)
Disk I/O Timeout(Sec):
is the time interval for the subsystem to wait for a drive to respond to I/O
requests. Selectable intervals range from 1 to 10 seconds.
SAF-TE/SES Device Check Period(Sec): If there are enclosure
devices in your RAID enclosure being monitored via SAF-TE/SES, use this function
to decide at what interval the subsystem will check the status of these devices.
Drive Fail Swap Check Period(Sec): The subsystem scans drive
busses at this interval to check if a failed
drive has been replaced.
Maximum Tag Count:
The subsystem supports tag command queuing with an adjustable
maximum tag count from 1 to 128. The default setting is “Enabled”
with a maximum tag count of 32.
Spindown Idle Delay Period (Sec): Setup an idle period for the drives. Drives will automatically spin down while there is no read/write command to drives within the idle period. Then if any I/O command is issued, such as disk backup, the drives will wake up and serve the I/O requirement. This feature rises up drives' usage life. (Note: This function is only applicable on RAID subsystems running Firmware 3.47 or above version with SATA HDD configured.)
Bad Block Reassignment Threshold: Trigger the bad block reassignment function by selecting a percentage of a defective drive. A warning message will be sent to a system administrator when the system detects the percentage of bad blocks. A system administrator should be noticed a drive error and attempt to replace the drive immediately. (Note: This function is only applicable on RAID subsystems running Firmware 3.47 or above version with SATA HDD configured.)
