Chassis support
The x240 is supported in the Flex System Enterprise Chassis.
Up to 14 x240 Compute Nodes can be installed in the chassis, however, the actual number that can be
installed in a chassis depends on these factors:
The TDP power rating for the processors that are installed in the x240
The number of power supplies installed in the chassis
The capacity of the power supplies installed (2100 W or 2500 W)
The chassis power redundancy policy used (N+1 or N+N)
The following table provides guidelines about what number of x240 Compute Nodes can be installed. For
more guidance, use the Power Configurator, found at the following website:
http://ibm.com/systems/bladecenter/resources/powerconfig.html
In the table:
Green = No restriction to the number of x240 Compute Nodes that are installable
Yellow = Some bays must be left empty in the chassis
