Removing Dimms - Intel SSR212CC User Manual

— If the DIMM in socket 1A fails, the DIMM in socket 1B takes over.
— If the DIMM in socket 2A fails, the DIMM in socket 3B takes over.
— If the DIMM in socket 2B fails, the DIMM in socket 3A takes over.
For memory on-line sparing, one DIMM per channel is used as the memory spare. The
spare DIMM is not available for use, but is kept in reserve. If a DIMM begins to fail, the
content of the failing DIMM is copied to the spare DIMM in that channel. When all of the
data is copied to the spare DIMM, the primary DIMM is removed from service and the
spare DIMM takes its place.
When memory on-line sparing is used, the spare DIMMs must be equal to or larger than
the largest in-service DIMM in that channel.
