Limited maximal number of compute node in the same chassis

The following chart describes the maximal number of SN550 V2 compute node that can be installed in Flex chassis.

The exact maximal number of supported 1-bay nodes is determined by input voltage and power redundancy policy. See the following table for detailed combinations, or alternatively, refer to Lenovo Capacity Planner for more details.

Note that the values in this table are based on power policy with compute node throttling allowed.
