Preface
Features
Hot-spare memory technology is also supported, whereby one memory module
is used as a replacement for two other memory modules. If a memory module
fails, the module with the defective memory is deactivated automatically and the
replacement module is activated (provided that it has been configured
accordingly in BIOS; see
BIOS Setup
). The deactivated memory module is no
longer used and the faulty memory module can be replaced at the next
opportunity. In order to use the hot-spare memory function, all occupied
memory spaces in a channel must have an identical memory configuration.
Memory modules can be protected against failure by mirroring (Memory
Mirroring). Memory Mirroring is roughly comparable to RAID level 1 for hard disk
arrays.

For further information according to memory mudule population please
refer to the technical manual of the system board D2619.
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 Analysing) technology from Fujitsu
Technology Solutions analyzes and monitors all components that are critical for
system reliability.
The RAID functionality of the SAS RAID controller supports RAID levels 0, 1,
10, 1E, 5 and 50 and increases the availability of the system.
The hot-plug HDD modules provide additional availability.
