Functional overview
Accessible drives/components
A number of mounting locations are available:
– An installation slot for a ServerView Local Service Panel (optional) or a Front
VGA and LAN module (optional)
– An installation slot for a slimline DVD drive (optional)
The accessible drives/components integrated in this locations cannot be
replaced during operation.
Power supply
In its basic configuration the server has a standard power supply unit or a hot-
plug power supply unit that adjusts automatically to any mains voltage in the
range 100 V - 127 V or 200 V - 240 V. Besides the hot-plug power supply unit,
a second hot-plug power supply unit can be installed optionally to serve as a
redundant power supply. If one power supply unit fails, the second power supply
unit in the redundant configuration ensures operation can continue
uninterrupted.
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.
