GPU Card Configuration Rules
The rules for configuring the server with GPUs differ, depending on the server version and other factors.
Observe the following rules when populating GPUs in the server:
• All GPU cards require two CPUs and two minimum 1400 W power supplies in the server.
•
For riser 1, use version 1A (slot 2) for GPU cards. This server can be ordered with one of three PCIe
riser 1 versions. GPU cards are not supported in version 1B (UCSC-PCI-1B-240M4) or 1C
(UCSC-PCI-1C-240M4).
• GPU cards are also supported in PCIe riser 2, slot 5.
Caution
Cisco C240 M4 LFF and C240 M4 SFF 24-drive servers only: When using NVIDIA GPU cards, you
must preserve at least 10 mm of space between servers to ensure adequate air flow. When using GPU cards
with this version of the server, the operating temperature range is 32° to 95° F (0° to 35° C).
•
Mixing rules:
– You can mix GRID K1 and K2 GPU cards in the same server.
–
Do not mix GRID GPU cards with Tesla GPU cards in the same server.
– Do not mix different models of Tesla GPU cards in the same server.
•
NVIDIA GPUs can support only less-than 1 TB of memory in the server. Therefore, do not install
more than fourteen 64-GB DIMMs when using an NVIDIA GPU card in this server.
• Table D-2 shows the rules for populating GPU cards in the server.
Note
You can install a GPU card and a Cisco UCS VIC in the same riser. When you install a GPU card in slot
2, NCSI support in riser 1A automatically moves to slot 1. When you install a GPU card in slot 5, NCSI
support in riser 2 automatically moves to slot 4.
