Functional overview
Accessible drives/components
Two mounting locations are available:
– a 3.5-inch bay for a backup drive.
– a 5.25-inch bay with a slimline DVD drive.
The accessible drives cannot be replaced during operation.
Power supply
The server has a built-in power supply unit, which automatically sets itself to a
mains voltage in the range 100V - 240V.
High level of availability and data security
When memory data is accessed, 1-bit errors are identified in the main memory
and automatically corrected with the error correcting code (ECC) method.
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.
A RAID controller supports different RAID levels and increase the availability
and data security of the system.
The hot-plug HDD modules provide additional availability.
