DL980 memory hemisphere question
Can anyone please find out what happens in the flowing case:
Memory configuration is Hemisphere.
The BIOS deallocated a DIMM.
What happens with Hemisphere mode?
Per the picture below, is there a difference on how the server is configured, and what happens with a DIMM failure?

Re: DL980 memory hemisphere question
The 980 only supports hemisphere mode.
In the case of a single memory board failure, the memory board it is paired with will be disabled.
In other words, both memory boards in a pair are required to be functional, and if not, neither will be used.
The answer is for the case of memory board failures. In the case of a DIMM failure, the entire Quad (4 DIMMs) of memory is dealocated. The DIMM deallocation rules are such that the system always runs in hemisphere mode.
