Introduction
Accessible drives
The first (top) bay contains the server's DVD drive. The fourth (bottom) bay can
be used for a 3.5” disk drive (1.44 Mbyte).
The two middle 5.25” bays are available for additional usable drives (CD/DVD
drives or a magnetic tape drive). Alternatively, these two bays can be used to
install the HDD extension box (this is only possible for the SAS server variant).
The accessible drives cannot be replaced during operation.
Power supply
With the basic configuration, the server has a fixed power supply unit. One or
two redundant hot pluggable power supply units are available as an option. If a
power supply unit is defective, in a redundant configuration the other unit
ensures that the operation can continue with no interruptions. The defective
power supply unit can be replaced during operation (hot plugging). Both power
supply unit versions automatically adjust to a mains voltage in the range
100 V - 240 V.
High level of availability and data security
When memory data is accessed, 1-bit errors in the main memory are identified
and automatically corrected with the ECC (Error Correcting Code) method.
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
case of an error and automatically “hides” the defective system components.
The PDA (Prefailure Detection and Analyzing) technology from Fujitsu Siemens
Computers analyzes and monitors all components that are critical for system
reliability.
Optional pluggable RAID controllers support different server RAID levels and
increase the availability and data security of the system.
The hot plug compatible HDD modules provide additional protection.
