Microprocessor The server comes with two processor boards and one microprocessor. It supports a maximum of four microprocessors (two on each of the processor boards). The system board contains two processor-board connectors: one is primary; the other is secondary. You must maintain a processor board in each connector. The server can operate as an SMP server. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors. This enhances performance for applications, such as database transaction processing, Internet applications, and groupware. Notes Be sure you have: Thoroughly reviewed the documentation that comes with the microprocessor, so that you can determine whether you need to update the server's basic input/output system (BIOS). The latest level of BIOS for the server is available through the World Wide Web and the IBM PC Company Bulletin Board System (BBS). See "Online Support" on page iii for the appropriate World Wide Web addresses and bulletin-board telephone numbers. Obtained an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.us.pc.ibm.com/servers/ on the World Wide Web. To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use the same speed and voltage as those of the currently installed microprocessor. Microprocessor internal and external clock frequencies must be identical. 108 Netfinity Server HMM
