2.3.2 PCI Hot-plug
The PCI hot-plug function enables PCI cards to be added or removed under the
Solaris Operating System without a system reboot.
Examples of uses for the PCI hot-plug function are as follows:
■ Replacing or removing a faulty PCI card or one that will probably become faulty,
during system operation
■ Adding a PCI card during system operation
For details on the PCI hot-plug function, see the SPARC Enterprise M8000/M9000
Servers Service Manual.
2.3.3 Capacity on Demand
Capacity on Demand (COD) is an optional service that allows the user to purchase
spare processing resources (CPUs) for the servers. The spare resources are provided
in the form of one or more CPUs on COD boards that are installed on your server.
However, to access these CPUs, you must first purchase the COD right-to-use (RTU)
licenses for them.
Note – RTU means a license applicable to each CPU. To use CPUs with the extra
number of CPU RTUs purchased beforehand, the user needs to purchase additional
RTUs processors on each system board. The right-to-use license for CPUs specifies
the number of CPUs that can be used in the entire system. The system administrator
decides the system boards and domains to which the Right to Use is to be assigned.

For details on RTU assignment, see Section 3.2.2.6, “Resource Management” on
page 3-5.

Administration Guide.
2.3.4 Zones
The Solaris 10 OS has a function called Zones that divides the processing resources
and allocates them to applications.
