2-1 Section 2 Cell Component Express5800/A1160 Cell In Express5800/A1160 systems, hardware components are organized into cells. The main components of a cell are • Main logic module that hosts the proce ssors, processor voltage regulator modules, and node controller.
Processors 2-2 Figure 2-1 Basic Cell Processors Within each cell, the processor board in t he main logic module hosts the processors. The processor board contains the proce ssor sockets, processor voltage regulator modules, node controller, and the scalability ports, which are the ports that enable you t o connect up to four cells.
Processors 2-3 Figure 2-2 shows the location of the processor sockets (along with the processor number) on the processor board.
