Note: CMM2 firmware should be 1.6.1 or later to support ThinkSystem compute nodes
Up to seven SN850 servers can be installed in the chassis; however, the actual number that can be
installed in a chassis depends on the following factors:
TDP power rating for the processors that are installed in the SN850
Number of power supplies that are installed in the chassis
Capacity of the installed power supplies (2100 W or 2500 W)
Chassis power redundancy policy that is used (N+1 or N+N)
The following table provides guidelines about what number of SN850 servers can be installed. For more
information, use Lenovo Capacity Planner, which is found at the following web page:

The following color coding was used In the table:
Green = No restriction on the number of SN850 servers that can be installed
Yellow = Some bays must be left empty in the chassis
