Installing An Additional Microprocessor - IBM LS20 - BladeCenter - 8850 Installation And User Manual

Installing an additional microprocessor

The blade server comes with one or two microprocessors installed on the system
board. The blade server supports two microprocessors. With two microprocessors,
the blade server can operate as a symmetric multiprocessing (SMP) server. With
SMP, certain operating systems and application programs can distribute the
processing load between the microprocessors. If the blade server comes with one
microprocessor, you can install a second microprocessor.
Notes:
1. You can not remove the single microprocessor and replace it with a different
2. If you install a second microprocessor, you must install the same
To use SMP, obtain an SMP-capable operating system. For a list of supported

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
v If the blade server has two microprocessors, they must have the same cache
v If only one microprocessor is installed, it must be installed in the microprocessor
v For a list of microprocessors that the blade server supports, go to the
