Main memory
SDDC (Chipkill) is supported only for registered memory modules.
Main memory operating modes
There are four operating modes for the main memory:
– Independent channel mode (maximum population)
The populated memory of the six channels (A - F) can be used completely
(max. 144 GB).
– Mirrored channel mode (maximum security)
Only the populated memory of the two channels A and D can be used (max.
48 GB). The channels B and E serve as safeguarding against failure. The
memory belonging to the channels B and E contain the mirrored data of the
memory belonging to channel A and D. The channels C and F are not used.
– Performance channel mode (maximum performance)
The populated memory of the six channels (A - F) can be used completely
(max. 144 GB).
– Spare channel mode (large population and large security)
Only the populated memory of the four channels A, B, D and E can be used
(max. 96 GB). The channels C and F serve as safeguarding against failure.
I
Spare channel mode is only supported by Intel
processor series.
Depending on the mode of operation there are different population
requirements for the main memory.
