Using The Memory Ras Features - NEC N8100-1410F User Manual

Using the Memory RAS Features

The server has the memory mirroring and online spare memory features as well as the x4/x8 SDDC
ECC memory feature, which can automatically correct a memory error (multi-bit error) causing
system shutdown.
IMPORTANT:
features are not available in the normal memory configuration. (The
x4/x8 SDDC ECC memory feature can operate in any configuration.)
The memory area on the motherboard of the server is divided into two memory branches as shown
in the figure below.

The memory mirroring and online spare memory features keep memory redundancy between

status, respectively.
