Upgrading Your Server 9-45
Using the Memory RAS Features
The server has RAS feature including "Standard memory configuration (x4 SDDC ECC memory)",
a "memory mirroring feature", a "memory sparing feature", and a "memory LockStep (x8 SDDC
ECC memory) feature". SDDC (Single Device Data Correction) allows automatic correction of
memory error (multi-bit error).
IMPORTANT:
To use the memory mirroring feature or memory LockStep (x8
SDDC ECC memory) feature, an additional memory stick
(N8102-392/393/394/395/396) is required.
To use x4 SDDC ECC memory feature and memory sparing feature,
an additional memory stick (N8102-379/380/381/382/383) is
required.
The memory area on the motherboard of the server is divided into two memory channels as shown
in the figure below.
The memory mirroring, memory sparing and memory LockStep features keep memory redundancy
between memory channels by monitoring or altering memory active/inactive status, respectively.
