4. How to UseUser Guide Page 4-23SMART Mode – S.M.A.R.T. is a monitoring system of disk drives to detect and report onvarious indicators of reliability, in the hope of anticipating failure. ExaSAN RAID systemsupports S.M.A.R.T. Once this function is selected, you can select the check interval from thedrop-down list. Choose from 1 minute to 8 hours for SMART Mode to be active. The RAIDcontroller will command each hard disk to perform S.M.A.R.T. according to the check intervalselected. 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 higherthe check frequency, the more the sequential access is influenced. It is recommended to turn offS.M.A.R.T. if high frequency is needed. On the other hand, running S.M.A.R.T. constantlyallows 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 ofan 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 thefollowing 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 cannot be guaranteed at all times. This feature allows the continuous I/Os to operate moresmoothly and substantially reduce large fluctuations in efficiency during data transfer. For videoediting, enable equalization to prevent video frame drops.Figure 61: EQ mode concept
