SMART Mode – S.M.A.R.T. is a monitoring system of disk drives to detect and report on
various indicators of reliability, in the hope of anticipating failure. ExaSAN RAID system
supports S.M.A.R.T. Once this function is selected, you can select the check interval
from the drop-down list. Choose from 1 minute to 8 hours for SMART Mode to be active.
The RAID controller will command each hard disk to perform S.M.A.R.T. according to the
check interval selected. The check results will be shown as an Event message in the
main menu.
When running S.M.A.R.T., the performance of the system will be slightly affected. The
higher the check frequency, the more the sequential access is influenced. It is
recommended to turn off S.M.A.R.T. if high frequency is needed. On the other hand,
running S.M.A.R.T. constantly allows you to monitor the conditions of hard disks at any
time.
Different hard disk models and brands will have different attributes in the reporting of
S.M.A.R.T. Event message will show all messages generated by the hard disk.
Beeper – If the Beeper option is enabled, the system will sound an audible alarm in the
event of an error. Users can respond to the error promptly and carry out
troubleshooting.
If the error indicated by the Beeper alarm has been resolved, you may perform one of
the following to turn off the alarm.
1. Uncheck the Beeper option.
2. Press the “Mute” button on the front panel.
Equalization Mode – Regardless the transmission method, the data transmission speed
can not be guaranteed at all times. This feature allows the continuous I/Os to operate
more smoothly and substantially reduce large fluctuations in efficiency during data
transfer. For video editing, enable equalization to prevent video frame drops.
