Features Preface
Accessible drives
The server has three 5.25-inch bays that can be used in various ways:
The individual bays can be equipped with any 3.5-inch drives (height:1.6 inch).
You can install a multibay (DVD-LSD/LSP) in the top bay. You can install a
slimline DVD drive and the ServerView Local Service Display or ServerView
Local Service Panel in the multibay (DVD-LSD/LSP).
I Please note the following:
A DVD drive must have been installed in order to operate the server.
The accessible drives cannot be replaced during operation.
You are required to open the drive cover of system when you access
to the 5.25 inch drives.
Power supply
In its basic configuration the server has a permanently installed power supply
unit or a hot-plug power supply unit that adjusts automatically to any mains
voltage in the range 100 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.
