6.4.3 Memory Redundant Function

Memory redundant functions (memory mirroring function, memory sparing function) can be set in this
server. This section explains installation conditions and BIOS settings.
Memory mirroring function
Install two memory boards and change the settings with the BIOS setup utility to use the memory
mirroring function. Memory mirroring consists of memory board 1 and 2. The available memory
capacity (logical capacity) is half of the physical capacity. Data is stored in memory board 1 and 2.
Even if an irrecoverable memory failure occurs, OS operation will continue. After a memory failure
occurs, the memory mirroring configuration cannot be maintained and the memory mirroring function is
disabled.
Installation conditions
Install memory modules that have the same capacity in the same slots of memory board 1 and 2.
BIOS settings
After installing the memory modules, perform the following settings to enable the memory mirroring
function.
1
Install the memory modules.
"6.4.4 How to Install or Remove Memory Modules" (p.150)
2
Start the BIOS Setup Utility.
