If you require more than four processors, you can create a single scalable system
by connecting up to three additional x3950 M2 systems. You may also upgrade
any x3850 M2 system to a scalable x3950 M2 system as described in 1.2.4,
"Scalable upgrade option for x3850 M2" on page 11.
Every processor in such a multinode configuration must be identical — same
processor type, speed, and cache size. The number of processors in each node
in the configuration may vary, so you can have a three-node configuration where
the nodes have two, three and two processors respectively, for a total of seven
processors.
Note: If you have a multinode complex and one or more nodes has only one
processor installed, and that node fails, then the complex will automatically
reboot without the memory resources and I/O resources that were in that
node. Therefore from a system availability perspective, we recommend you
have at least two processors in every node.
3.1.1 Processor options
Table 3-1 on page 91 lists the processors supported in the x3950 M2 and
x3850 M2 (machine type 7141/7144) with Xeon 7200 and 7300
processors. Each processor option includes a CPU, heat-sink, and VRM.

a. Thermal Design Power (TDP): The thermal specification shown is the maximum case temperature
at the maximum TDP value for that processor. It is measured at the geometric center on the topside
of the processor integrated heat spreader. For processors without integrated heat spreaders, such
as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The
maximum junction temperature is defined by an activation of the processor Intel Thermal Monitor,
which has an automatic mode to indicate that the maximum Tj has been reached.
b. The first feature code is the base configuration. Additional processor orders should use the second
feature code.
