2.3.3 Capacity on Demand (COD)
The COD feature allows you to configure spareprocessing 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. Toaccess each COD
CPU, you must purchase a COD hardware activation permit. Under certain
conditions, you can use COD resources before purchasingCOD permits for them.
For more information, refer to the SPARCEnterprise 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 processingresources
and allocates them to applications. Zones provide flexible resourceallocation, which
enables optimal resource management with consideration given to the processing
load.
In a domain, resourcescan be divided into sections called containers. The processing
sections are allocated to each application. The processing resources aremanaged
independently in each container.If a problem occurs in a container, the container can
be isolated so it does not affect other containers.
