Partitioning the SX130 model series

All SX130 models have a basic configuration with two system boards.
These either form one partition with two system boards for the

first BS2000/OSD instance or two partitions with one system board
each for the first BS2000/OSD instance and the first Solaris in-

stance. Depending on the model, two additional system boards can be
optionally installed, which can then be used as follows:

a) a second OSD/XC instance with two system boards
b) one Solaris instance with one or two system boards

c) two Solaris instances with system board each

Alternative a) provides you with the option of configuring two
identically defined partitions with mutual monitoring (cluster in a

box).

Partitioning the SX140 model series

The basic configuration SX140 series server contains one main
board. This can be split into a maximum of four so-called Extended

System Boards (XSBs).
Extended Partitioning (XPAR) can be set up on this basis with up to

four separate systems where specific rules apply for populating the
main boards and for assignments between processors, memory modules

and PCI slots.
Installing a second system board increases the possible number of

XPAR partitions to eight. In addition to XPAR partitioning, physi-
cal partitioning (PPAR) can also be used. This configures a main

board into a single partition that has other assignment rules.
A different operating system, OSD/XC or Solaris can be run in each

partition, independent of the other partitions.

Partitioning the SX150 model series

The basic configuration of a server from the SX150 series contains
one system board and as of SX150C two boards. Each system board can

be split into four so-called extended system boards (XSB) via the
XPAR mechanism.

Installing a second system board into servers SX150-10A to
SX15020C, then also allows a maximum of eight partitions on these

servers via XPAR.

Physical partitioning (PPAR) with which a system board can be con-
figured into a single partition is also possible, in addition to

partitioning with XPAR. A separate operating system (OSD/XC or So-
laris) can be used in each partition (via XPAR or PPAR), independ-

ently of the other partitions.

2.5 Dynamic systemboard reconfiguration (DR) on SX150 server

The SX150 supports dynamic system board reconfiguration for both

Solaris and BS2000 partitions, where either BS2000 or VM2000 can be
used in the BS2000 partition. The BS2000 partitions must be parti-

tioned via XPAR for this. The configuration of the SX150 standard
models may have to be extended, depending on the usage scenario for

dynamic reconfiguration.
