Cpus And Dimms; Physical Layout - Cisco UCS C200 M2 Spec Sheet

CPUs and DIMMs

Physical Layout

Each CPU has three DIMM channels:
CPU1 has channels A, B, and C.
■
CPU2 has channels D, E, and F.
■
Each DIMM channel has two banks: Bank 1 and Bank 2. The blue-colored DIMM banks are for Bank 1 and the
black-colored are for Bank 2.
As an example, DIMM slots A1, B1, and C1 belong to Bank 1, while A2, B2, and C2 belong to Bank 2.
Figure 8 shows how banks and channels are physically laid out on the motherboard. The DIMM slots on the
right (channels A, B, and C) are associated with CPU1, while the DIMM slots on the left (channels D, E, and
F) are associated with CPU2. The Bank 1 (blue) DIMM slots are always located farther away from a CPU than
the corresponding Bank 2 (black) slots. Bank 1 slots are populated before Bank 2 slots.
