54 SPARC Enterprise Mx000 Servers Administration Guide • August 2009
The number of domains allowed depends on server model. The default is one
domain (the maximum for entry-level servers) 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 4-6 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.
