Pci Hot-Plug; Capacity On Demand (Cod); Zones - Fujitsu SPARC ENTERPRISE M5000 Overview Manual

2.3.2

PCI Hot-Plug

You can insert and remove PCI cards for certain PCIe and PCI-X hot-plug controllers
while the server is running. Before you can remove a PCI card, you must first
unconfigure and disconnect it using the Solaris cfgadm(1M) command. For more
information, refer to the SPARC Enterprise M4000/M5000 Servers Service Manual.
2.3.3

Capacity on Demand (COD)

Capacity on Demand is an option that allows you to purchase spare processing
capacity for both servers. The spare capacity is provided in the form of one or more
CPUs on COD boards that are installed on your server, but require a license to use. In
other words, the COD boards themselves are free, but to use their processing
capacity, you must purchase a license. Under certain conditions, you can also use
COD boards as headroom before purchasing a license.
For more information, see the SPARC Enterprise M3000/M4000/M5000/M8000/M9000
Servers Administration Guide.
2.3.4

Zones

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.
