This section provides the CMM installation order in configurations with two processors.
Figure 1. E3.S backplane numbering
Note
E3.S backplane installation order: BP1, BP5, BP3, BP7, BP2, BP6, BP4, BP8
Installation priority: E3.S 1T drive > E3.S 2T CMM.
When the CMM mode is 1LM+Vol, 4/8/12 CMMs are supported in configurations with two processors.
When the CMM mode is Hetero, 8 CMMs are supported in configurations with two processors.
1T: E3.S 1T hot-swap drive; 2T: E3.S 2T non-hot-swap CXL memory (CMM)
