Configuring Memory Mirroring

This section describes how to configure memory mirroring.
Note - The memory mirror configurations are optional.
The SPARC M10 systems support 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 M10 systems configure 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.
