A domain consists of one or more XSBs. Each domain runs its own copy of the Solaris OS. A domain must have, at a minimum, 1 CPU, 8 DIMMs, and I/O.

In FIGURE 4-3, one domain (for example, domain 0) must contain XSB 00-0, and the second domain (for example, domain 1) must contain XSB 00-1, because of the I/O requirement for a domain. The remaining XSB 00-2 and XSB 00-3 can be assigned to either domain, or to none.
