The figure below shows a logical view of the DIMMs and channels.
Figure 17: Logical Representation of DIMMs and Channels
DIMMs can be used in the blade server in a one DIMM per Channel (1DPC) configuration, in a two DIMMs
per Channel (2DPC) configuration, or a three DIMMs per Channel (3DPC) configuration.
Each CPU in a Cisco UCS B200 M4 blade server supports four channels of three memory slots each. In a 1
DPC configuration, DIMMs are in slot 1 only. In a 2 DPC configuration, DIMMs are in both slot 1 and slot
2. In a 3 DPC configuration, DIMMs are in slot 1, slot 2, and slot 3.
