Fujitsu PRIMERGY RX600 S6 Operating Manual page 17

Preface
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
the event of an error and automatically "hides" the defective system
components.
The PDA (Prefailure Detection and Analysis) technology from Fujitsu analyzes
and monitors all components that are critical for system reliability.
The SAS/SATA controller card supports the RAID levels 0, 1, 1E, 5, 6, 10, 50
and 60 thus increasing system availability and reliability.
Additional reliability is provided by the hot-plug HDD/SSD modules, fans and
power supply units.
