Upgrading Your Server 9-31
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:
The memory mirroring and online spare memory
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
memory branches and within a memory branch by monitoring or altering memory active/inactive
status, respectively.
