Installing A Microprocessor - IBM xSeries 330 Hardware Maintenance Manual

Installing a microprocessor

The server comes with one or two microprocessors installed on the system board.
If you have two, or had one and you installed a second microprocessor, the 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. This enhances performance for database and
point-of-sale applications, integrated manufacturing solutions, and other
applications.
Notes:

microprocessor in microprocessor connector 2, the two microprocessors will
share the system load after the system has started.
