system board In the SPARC Enterprise M8000/M9000 server, a system board consists of a
CPU and memory on the CPU/Memory Board Unit (CMU) and I/O devices in
the I/O Unit (IOU). In the SPARC Enterprise M4000/M5000 server, a system
board consists of a CPU module and memory board on the Motherboard Unit
(MBU) and I/O devices in the I/O Unit (IOU). The system board is classified
into two types, PSB and XSB, depending on the configuration. In the SPARC
Enterprise 3000 server, a system board consists of a CPU and memory on the
Motherboard Unit (MBU) and PCIe cards on the PCIe slot.
system control network
A network that connects the XSCF Unit (XSCFU) to the administration
console for the system administrator's use.
