Number Of Cpus And Number Of Root Complexes; Maximum Number Of Each Type Of Mounted Pci Card And Available; Pci Slots - Fujitsu SPARC M12 Installation Manual

If an Oracle Solaris 10 environment is used in the following configurations, apply the
rules for Oracle Solaris 11.
A guest domain of an Oracle Solaris 10 environment is configured using the
■
virtual I/O services of a control domain or the root domain of Oracle Solaris 11.
An Oracle Solaris 10 zone is configured on an Oracle Solaris 11 domain.
■
If there are plans to add a root domain or I/O domain of Oracle Solaris 10 after the
start of system operation, apply the rules for Oracle Solaris 10.
Note - For details on the design of control domain, root domain, and I/O domain configurations,
see the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
2.1.2

Number of CPUs and Number of Root Complexes

A root complex consists of an I/O controller mounted on a processor and the PCI
switches, PCI devices, etc. under the I/O controller.
The number of root complexes varies depending on the CPU configuration, and the
maximum number of mounted PCI cards and the available PCI slots vary depending
on the number of root complexes.
For cases of CPU module expansion after the installation of equipment to change to
the 2-CPU configuration, if the I/O bus is not reconfigured, apply the rules for the
1-CPU.
For details on root complexes, see
and Number of Root
Note - For cases of CPU module expansion after the installation of equipment to change to
the 2-CPU configuration, the recommended configuration is one with four root complexes.
This configuration inherits the I/O bus configuration and mounting rules of the 1-CPU
configuration. Changing the configuration into one with eight root complexes increases the
maximum number of mounted PCI cards. However, system reconfiguration is required
because the I/O bus is reconfigured.
2.2 Maximum Number of Each Type of
Mounted PCI Card and Available PCI
Slots
For the maximum number of each type of mounted PCI card and the available PCI
slots, see
"Maximum Number Mounted" means the maximum number of PCI cards that can
■
be mounted in the SPARC M12-2 and the PCI expansion unit. The numbers in ( )
indicate the slot numbers where cards can be mounted, among the PCI slots of the
