SMART Technology
The MegaRAID Express 500 Self Monitoring Analysis and Reporting Technology
(SMART) detects up to 70% of all predictable drive failures. SMART monitors the
internal performance of all motors, heads, and drive electronics.
Configuration on Disk
Configuration on Disk (drive roaming) saves configuration information both in
NVRAM on MegaRAID Express 500 and on the disk drives connected to MegaRAID
Express 500. If MegaRAID Express 500 is replaced, the new MegaRAID Express 500
controller can detect the actual RAID configuration, maintaining the integrity of the data
on each drive, even if the drives have changed channel and/or target ID.
