3.2.1 Partitioning Design Rules (2/2)
The Total Numbers of System Boards/Memory Scale-up Boards and

CPUs per Partition
When multiple SBs are used to configure a partition:

• For the 2800B2/2800B3/2800E2/2800E3, two CPUs must be installed in each SB.
• For the 2400E2/2400E3, the same number of CPUs must be installed between the SBs.
When 128GB DIMMs are used, a single partition can only be configured with one SB.

A single partition cannot be configured with multiple SBs.
In a default configuration, an SB with two CPUs and an SB with one CPU in one

partition (2SB-3CPU) cannot be installed.
