Nytro MegaRAID Revision 1.7 Overview : Solid State Drive Features : The SSD Guard Feature

The SSD Guard Feature

The SSD Guard™ feature is unique to Nytro controller, which increases the reliability of SSDs by automatically copying data from a drive with the potential to fail to a designated hotspare or newly inserted drive. The SSD Guard feature adds data protection for RAID 0 configurations.

The SSD Guard feature looks for a predictive failure while monitoring the SDD Self-Monitoring, Analysis, and Reporting Technology (SMART) error log. If errors indicate that an SSD failure is imminent, the Nytro controller starts a rebuild operation to preserve the data on the SSD and sends appropriate warning event notifications.
