FBDIMMs can either be single-rank or dual-rank. Certain FBDIMM configuration requirements are based on these classifications. A
dual-rank FBDIMM is similar to having two separate FBDIMMs, or ranks, on the same module. Although only a single FBDIMM
module, a dual-rank FBDIMM acts as two separate FBDIMMs.
In online spare mode, a single rank of memory acts as the spare memory. For single-rank FBDIMMs, the entire FBDIMM acts as the
spare memory. For a dual-rank FBDIMM, only half of the FBDIMM acts as the spare memory while the other half is available for
operating system and application usage.
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.
For optimum memory usage, HP recommends all FBDIMMs be the same size with the same HP part number. If different sized
FBDIMMs are used, a portion of the installed memory may not be utilized.
In online spare mode, FBDIMMs must be populated as specified in the following table:
Configuration 1 (Bank A only) is only supported if using bank A, populated with dual-rank FBDIMMs.
After installing FBDIMMs, use RBSU to configure the system for online spare memory support.
