The blade server operates as a symmetric multiprocessing (SMP) server, regardless of how many
microprocessors are installed. For optimum performance, you must upgrade the operating system to
support SMP. See Chapter 5 "Installing the operating system" on page 65 and your operating-system
documentation for additional information.
Input/output connectors and devices
Use this information to locate the input/output connectors and devices.
The input/output connectors that are available to the blade server are supplied by the BladeCenter unit. See
the documentation that comes with the BladeCenter unit for information about the input/output connectors.
The blade server has two selection buttons on the control panel: the media tray select button and the
keyboard/video/mouse select button. See "Blade server controls and LEDs" on page 11 for information
about these buttons and their functions.
The Ethernet controllers on the blade server communicate with the network through the Ethernet-compatible
I/O modules in the BladeCenter unit. Network signals to and from the blade server or any expansion cards
are automatically routed to a same-network-interface I/O module through circuitry in the BladeCenter unit.
