Description General information
Accessible drives
A 3.5-inch floppy disk drive (1.44 MB) and three bays for the installation of
accessible drives (CD-ROM, DVD-ROM, CD burner or tape drive) are available.
The accessible drives cannot be replaced during operation.
In the SCSI version it is possible to install a HDD extension box in two bays of
the accessible drives.
Power supply
In its basic configuration level the server has a fixed power supply unit (standard
power supply) that adjusts automatically to a power voltage in the range from
100 V - 240 V.
As an option, this power supply unit can be replaced with a hot-plug power
supply unit (redundant power supply) which consists of two power supply
modules in the maximum configuration. To achieve redundant power supply the
second power supply module must be added.
If one power supply module of the redundant power supply unit fails, the second
power supply module ensures unimpaired continued operation and the
defective power supply module can be replaced during operation (hot-plug).
High level of availability and failure protection
When accessing stored data, 1-bit-errors in the main memory are automatically
recognized and corrected by ECC mechanism (ECC = Error Detection Code).
ASR&R (Automatic Server Reconfiguration and Restart) tunes out defective
system components during an automatic system reboot.
The Prefailure Detection and Analysing Technology (PDA) analyzes and
monitors all components that are vital for the system's reliability.
Optional RAID controllers increase system availability and support the RAID
levels 0,1 and 5.
The hot-plugable hard disks provide additional protection.
Server management
Server management is implemented with aid of the supplied ServerView
software and PDA (Prefailure Detection and Analyzing) technology. PDA reports
the threat of system errors or problems to the system administrator so that
preventative measures can be taken.
