Cisco Cisco UCS C420 M3 Rack Server Datenbogen

■

NVIDIA GRID K1 and K2 GPUs can be mixed. No other GPU mixing is allowed.

■

You cannot mix the K80 with any other GPU

■

You must order one power cable for each GPU you order. The power cable plugs into the 
motherboard GPU power connector and to the appropriate GPU(s).

■

Slot 7 is the preferred slot for the first GPU.

■

You cannot have a GPU installed in slot 7 and at the same time have a QLE2562 HBA 
(N2XX-AQPCI05) installed in slot 9.

■

Systems with 64 GB DIMMs cannot implement any GPUs.

■

If any GPU is installed, the maximum amount of DIMM memory allowed in the server must be 
less than 1 TB (for example, UCS-MR-2X162RY-E (2x16 GB) cannot exceed a quantity of 30, or 
UCS-ML-2X324RY-E (2x32 GB) cannot exceed a quantity of 14, or UCS-MR-1X162RU-G (1x16 
GB) cannot exceed a quantity of 60, or UCS-MR-1X322RU-G (1x32 GB) cannot exceed a 
quantity of 28).

NOTE:  A 2-CPU configuration can have 1 GPU maximum and a 4-CPU configuration 
can have up to 2 GPUs. Any configuration that includes a GPU requires four 1400 W 
power supplies in the server.

NOTE:  An 8-pin power connector for the GPU is located on each PCIe riser. Connect 
a cable as appropriate from this connector to the power connector on the GPU.
