Device Mapping
The physical address represents a physical characteristic that is unique to the device.
Examples of physical addresses include the bus address and the slot number. The
slot number indicates where the device is installed.
You reference a physical device by the node identifier–agent ID (AID). The AID
ranges from 0 to 31 in decimal notation (0 to 1f in hexadecimal). In the device path
beginning with
ssm@0,0
the first number, 0, is the node ID.
This appendix describes device mapping nomenclature for the Netra 1290 server and
includes the following topics:

CPU/Memory Mapping
CPU/memory board and memory agent IDs (AIDs) range from 0 to 23 in decimal
notation (0 to 17 in hexadecimal). The server can have up to three CPU/memory
boards.
Each CPU/memory board has four CPUs, depending on your configuration. Each
CPU/memory board has up to four banks of memory. Each bank of memory is
controlled by one memory management unit (MMU), which is the CPU. The
following code example shows a device tree entry for a CPU and its associated
memory:
