Beginners Guide to LDoms: Understanding and Deploying Logical Domains

Posted by : Dr. Root | 14 June, 2007 | Published in

In essence, Sun's Logical Domains (LDoms) technology allows you to allocate a system's various resources, such as memory, CPUs and devices, into logical groupings and create multiple, discrete systems, each with their own operating system, resources, and identity within a single computer system. By careful architecture, a logical domains environment can help you achieve greater resource usage, better scaling and increased security and isolation.

Sun has published a blueprint which will help you gain a better understanding of how you can easily and effectively deploy Sun's Logical Domains technology.

It will help you determine how and where to use logical domains to the greatest effect using best practices. The document discusses strategies for deploying logical domains on the Sun Fire T1000 and T2000 systems -- the first systems to offer Logical Domain support -- and the various best practices for these platforms.

The guide works through step-by-step examples that include the commands to set up, deploy and manage logical domains and looks at commonly asked questions and advanced techniques.

The good thing about this guide is that it has been designed for several different levels of user and intended to be used as both an introduction to concepts and technologies, and as a handy reference for more complex approaches.
