Chapter 2 HP NetServer AA Overview Figure 2-3 Overview of IOP Boot Process After the IOPs complete their boot process, the CEs boot: one CE loads the Windows NT operating system; then the other CE is synchronized so that both CEs perform all CPU and memory functions in a tightly coupled manner. This ensures that in the event of a CPU or memory failure, the server operating system provides continuous computing without any loss of context. After the CE boot process completes, the server is available for use. For an IOP to service the CE boot request, it must have completed boot, as shown in Figure 2-3 and described in Appendix B. The CE boot process is summarized in Figure 2-4. A detailed CE boot process flowchart is in Appendix B. 18
