2.3.3 Capacity on Demand (COD)
The COD feature allows you to configure spare processing resources on your
M4000/M5000 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 more information, refer to the SPARC Enterprise M4000/M5000/M8000/M9000
Servers Capacity on Demand (COD) User’s Guide.
2.3.4 Zones
Oracle Solaris OS has a function called zones, which divides the processing resources
and allocates them to applications. Zones provide flexible resource allocation, which
enables optimal resource management with consideration given to the processing
load.
In a domain, resources can be divided into sections called containers. 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 it does not affect other containers.
