Chapter 4 Domain Configuration 49
The number of domains allowed depends on which midrange or high-end server
model you have. The default is one domain and the maximum number of domains is
24. Each domain is identified with a domain ID number, with the default domain as
#0.
TABLE 4-1 shows the maximum number of system boards, the maximum number of
domains, and the domain ID number range by server model.
Domains can be set up to include both Uni-XSBs and Quad-XSBs.
FIGURE 4-5 shows
two XSBs in Uni-XSB mode (left side of figure) and two XSBs in Quad-XSB mode
(right side of figure) on a high-end server; the partition of these boards into three
Solaris domains is shown by shading.
