General NVIDIA GPU Card Configuration Rules
Caution
When using NVIDIA GRID GPU cards, the operating temperature range is
32° to 95°F (0° to 35°C).
Caution
When using dual NVIDIA GPU cards, you must preserve at least 10mm of space between servers to
ensure adequate airflow and cooling. The only exception is for NVIDIA GRID K1 GPU cards, which do
not require this 10mm gap.
•
Mixing different GPU cards in the same server is not supported.
•
All GPU cards require two CPUs and two 1200 W power supplies in the server.
•
It is not possible to use dual NVIDIA GPU cards and a Cisco virtual interface card (VIC) at the same
time. This is because dual NVIDIA GPUs must be installed in slots 2 and 5 of the server, and a Cisco
VIC must be installed in either slot 2 or slot 5. If you require two GPU cards and 10-Gb Ethernet
connectivity, you must chooses a different supported adapter that can be used in a different slot. For
supported adapters, see the Technical Specifications Sheet for the Cisco UCS C240 M3 server
(Small Form Factor or Large Form Factor) at:

NVIDIA Tesla K40 Requirements
The NVIDIA Tesla K40 GPU card requires the following minimum items:
•
Intel E5-2600 v2 Series CPUs in the server
•
Cisco IMC and BIOS firmware minimum 1.5(7) or later.
NVIDIA GRID GPU Slot Population Rules
Table 3-11 shows the rules for populating NVIDIA GRID K1 or K2 GPU cards in the server.
NVIDIA Tesla GPU Slot Population Rules
Table 3-12 shows the rules for populating NVIDIA Tesla K20, K20X, and K40 GPU cards in the server.
Note
The NVIDIA Tesla K40 GPU card requires Intel E5-2600 v2 Series CPUs in the server.
Caution
When using dual NVIDIA Tesla GPU cards, you must preserve at least 10mm of space between servers
to ensure adequate airflow and cooling.
