Cisco UCS C240 M5 Service Manual

When using NVIDIA Tesla P100 12GB or 16GB GPU cards in this server, the maximum operating
temperature (air inlet temperature) for the server is 28° C (82.4° F).
Caution
When using NVIDIA Tesla P40 GPU cards in this server, the maximum operating temperature (air inlet
temperature) for the server is 32° C (89.6° F).
Caution
•
Use the UCS power calculator at the following link to determine the power needed based on your server
configuration: http://ucspowercalc.cisco.com
•
Double-wide GPU cards are supported in PCIe riser 1, slot 2 and in PCIe riser 2, slot 5.
GPU cards are not supported in all PCIe riser options. GPU cards are supported only in
the following riser options:
Note
•
PCIe riser 1 (UCSC-PCI-1-C240M5)
•
PCIe riser 2A (UCSC-PCI-2A-C240M5)
•
PCIe riser 2B (UCSC-PCI-2B-C240M5)
•
A double-wide GPU card installed in slot 2 also covers slot 4; a double wide GPU card installed in slot
5 also covers slot 6.
•
Do not mix different brands or models of GPU cards in the server.
•
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 1 automatically moves to slot 1. When you install a GPU card in slot 5,
NCSI support in riser 2 automatically moves to slot 4.
•
The NVIDIA Tesla P-series GPUs can support more than 1 TB of memory in the server. All other
NVIDIA GPUs (M-series) can support only 1 TB or less of memory in the server. Therefore, do not
install DIMMs totaling more than 1 TB capacity when using an M-Series NVIDIA GPU card in this
server.
Requirement For All GPUs: Memory-Mapped I/O Greater Than
4 GB
All supported GPU cards require enablement of the BIOS setting that allows greater than 4 GB of
memory-mapped I/O (MMIO).
•
Standalone Server: If the server is used in standalone mode, this BIOS setting is enabled by default:
Advanced > PCI Configuration > Memory Mapped I/O Above 4 GB [Enabled]
If you need to change this setting, enter the BIOS Setup Utility by pressing F2 when prompted during
bootup.
