1.5. 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 processors, processor voltage regulator modules,
and node controller. (The node controller interconnects the components of a cell
and provides the connection among the cells in a multiple-cell system.)
• Memory board that contains the DIMM sockets for the fully buffered DIMMs.
• I/O subsystem that includes the I/O riser board, PCIe carriers, and PCIe cards.
• Power supplies.
• Fan modules.
• Peripherals including drive tray and hard drives, DVD drive, and Serial Attached
SCSI (SAS) RAID controller.
• Management and maintenance components (EXPRESSSCOPE® Monitor and
management board).
Figure 1-3 illustrates the main components of a cell.
