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 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 2-1 illustrates the main components of a cell.
