Chassis support
The x440 is supported in the Flex System Enterprise Chassis. Up to seven x440 compute nodes can be installed in
the chassis in 10U of rack space. The actual number of x440 Compute Nodes that can be installed in a chassis
depends on these factors:
The TDP power rating for the processors that are installed in the x440
The number of power supplies installed
The capacity of the power supplies installed (2100 W or 2500 W)
The power redundancy policy used (N+1 or N+N)
The following table provides guidelines about what number of x440 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 x440 Compute Nodes that are installable
Yellow = Some bays must be left empty in the chassis
