Memory redundant functions (memory mirroring function and memory sparing function) can be set for
this server. This section explains installation conditions and BIOS settings.

Memory mirroring function

To use the memory mirroring function, change the setting in BIOS Setup Utility. The memory mirroring
consist of the memory board 1 and 2. Available memory capacity (logical capacity) will be reduced by a
half of the physical capacity. Data will be written to the memory board 1 and 2. The operating system
will continue to operate even when an uncorrectable memory error occurs. However, the system will

collapsed.
