IBM Flex System X6 Compute Nodes Product Guide 10

Chassis support

The X6 Compute Nodes are supported in the IBM Flex System Enterprise Chassis.

Up to seven X6 compute nodes can be installed in the chassis in 10U of rack space. The number of

scaled systems that can be installed is as follows:

Two-socket systems: Up to seven systems in an Enterprise Chassis



Four-socket systems: Up to three systems in an Enterprise Chassis



Eight-socket systems: One system in an Enterprise Chassis



It might also be possible to populate the remaining bays within the chassis with other standard or

double-wide nodes. The actual number of servers that can be installed in a chassis also depends on

these factors:

The TDP power rating for the processors that are installed in the server



The number of power supplies that are installed



The capacity of the power supplies that are installed (2100 W or 2500 W)



The power redundancy policy that is used (N+1 or N+N)



The following table provides guidelines about what number of X6 Compute Nodes can be installed. For

more information, 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 X6 Compute Nodes that are installable.



Yellow = Some bays must be left empty in the chassis.



are installed and the power redundancy policy that is used
