Cisco Cisco UCS C460 M1 High-Performance Rack-Mount Server 데이터 시트

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 DIMM banks 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.

 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. If only one DIMM is 
used for CPU 1, for example, it must be located in slot 2 (A1, channel A, bank 1); likewise, if only one DIMM 
is used for CPU 2, it must be installed in slot 2 (D1, channel D, bank 1).
