Configuring Memory Mirroring

This section describes how to configure memory mirroring.
Note - Configuring memory mirroring is optional.
Note - To configure memory mirroring, the SPARC M12-1 must be powered off.
The SPARC M12-1 supports memory mirroring configurations to protect data
through memory duplication. Data reliability increases, but the amount of available
memory is halved.
The memory access controller controls writing of data to memory and reading of
data from memory. The SPARC M12-1 configures the mirroring by grouping
memory into sets controlled by two memory access controllers.
Note - The memory grouped together in a mirroring group must all have the same capacity
and be the same rank.
Execute the showfru command to check memory mirror mode.

Memory mirror mode is set in the factory default settings.
