in Sun M4000,
To use a PSB in your midrange or high-end server, the hardware resources on the board must be logically divided and reconfigured as eXtended System Boards (XSBs). There are two modes of XSBs:
Uni-XSB
A PSB logically undivided and configured into one XSB
Contains all the resources on the board: 4 CPUs, 32 DIMMs, and I/O on a midrange and high-end server; 1 CPU, 8 DIMMs, and I/O on an entry-level server.
Quad-XSB (midrange and high-end servers only)
A PSB logically divided and configured into four XSBs
Each of the four XSBs contains one-quarter of the total board resources: 1 CPU, 8 DIMMs, and I/O. On a midrange server, only two XSBs have I/O.
to change XSB mode, you have to power off all running domains.
