|System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones|
This book is part of a multivolume set that covers a significant part of the Solaris Operating System administration information. This book assumes that you have already installed the operating system and set up any networking software that you plan to use.
Note - This Solaris release supports systems that use the SPARC and x86 families of processor architectures. The supported systems appear in the Solaris OS: Hardware Compatibility Lists at http://www.sun.com/bigadmin/hcl. This document cites any implementation differences between the platform types.
In this document, these x86 related terms mean the following:
“x86” refers to the larger family of 64-bit and 32-bit x86 compatible products.
“x64” relates specifically to 64-bit x86 compatible CPUs.
“32-bit x86” points out specific 32-bit information about x86 based systems.
For supported systems, see the Solaris 10 Hardware Compatibility List.
A Solaris Container, also known as a Solaris Zone, is a complete runtime environment for applications. Solaris 10 Resource Manager and Solaris Zones software partitioning technology are both parts of the container. The zone provides a virtual mapping from the application to the platform resources. Zones allow application components to be isolated from one another even though the zones share a single instance of the Solaris Operating System. Resource management features permit you to allocate the quantity of resources that a workload receives.
The zone establishes boundaries for resource consumption, such as CPU. These boundaries can be expanded to adapt to changing processing requirements of the application running in the zone.
Solaris Containers for Linux Applications use Oracle's BrandZ technology to run Linux applications on the Solaris Operating System. Linux applications run unmodified in the secure environment provided by the non-global zone feature. This enables you to use the Solaris system to develop, test, and deploy Linux applications.
To use this feature, see Part III, lx Branded Zones.
For information on using zones on a Solaris Trusted Extensions system, see Chapter 10, Managing Zones in Trusted Extensions (Tasks), in Oracle Solaris Trusted Extensions Administrator’s Procedures.
This book is intended for anyone responsible for administering one or more systems that run the Solaris 10 release. To use this book, you should have at least one to two years of UNIX system administration experience.
Here is a list of the topics that are covered by the System Administration Guides.
Solaris Containers: Resource Management and Solaris Zones Developer’s Guide describes how to write applications that partition and manage system resources and discusses which APIs to use. Programming examples and a discussion of programming issues to consider when writing an application are also provided.

The goal of virtualization is to move from managing individual datacenter components to managing pools of resources. Successful server virtualization can lead to improved server utilization and more efficient use of server assets. Virtualization reduces costs through the sharing of hardware, infrastructure, and administration. Server virtualization is also important for successful server consolidation projects that maintain the isolation of separate systems.
