Chapter 3. IBM NeXtScale n1200 Enclosure 31
Table 3-3 shows the quantity supported of compute nodes with GPU trays
attached and two 130 W GPUs installed. Only 1300 W power supplies are
supported and only 200-240V AC input supported. The supported 130 W GPU is:

Note: Some cells indicate two numbers (for example “5 + 1”). This indicates
support for a mixture of servers with and without the GPU Tray:
First number: Number of servers with a GPU Tray attached and two GPUs
installed
Second number: Number of servers without a GPU Tray attached.
For example, “5 + 1” means Supported combination is
5 servers with the GPU
Tray attached, plus
1 server without a GPU Tray attached. In such a
configuration, the 1 remaining server bay in the chassis must remain empty.
