2.3.2 PCI Hot-plug
The PCI hot-plug function enables PCI cards to be added or removed under the
Oracle Solaris OS 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
The Capacity on Demand (COD) feature allows you to configure spare processing
resources on your server in the form of one or more COD CPUs which can be
activated at a later date when additional processing power is needed. To access each
COD CPU, you must purchase a COD hardware activation permit. Under certain
conditions, you can use COD resources before purchasing COD permits for them.
For details on COD, see the SPARC Enterprise M4000/M5000/M8000/M9000 Servers
Capacity on Demand (COD) User’s Guide
2.3.4 Oracle Solaris Zones
The Oracle Solaris 10 OS has a function called Oracle Solaris Zones that divides the
processing resources and allocates them to applications.
In a domain, resources can be divided into sections called containers, and the
processing sections are allocated to each application. The processing resources are
managed independently in each container. If a problem occurs in a container, the
container can be isolated so that it does not affect other containers. It provides
flexible resource allocation that enables optimal resource management with
consideration given to the processing load.
2.4 RAS
RAS is an acronym for functions related to Reliability, Availability, and Serviceability.
