Online spare memory configuration

Online spare FBDIMM configuration requirements (in addition to general configuration requirements):

When only bank A is being used, it must be fully populated with dual-rank FBDIMMs.

If banks A and C are being used, they must be fully populated.

If installed, bank A and bank C must contain FBDIMMs with identical part numbers.

If installed, bank B and bank D must also contain FBDIMMs with identical part numbers.

In online spare mode, FBDIMMs must be populated as specified in the following table:
