SmartOS Internals

Duration: 5 days

Description

This course answers the question, “How does the system work?”. It uses a combination of source code and various tools available on SmartOS to examine the topics that are covered. Tools used will include: DTrace, kmdb, mdb, and the /proc tools. Topics include: threads and processes, memory management, file systems, and I/O.

Objectives

On completion of this course, students will be able to:

  • Use DTrace, mdb, and kmdb to examine how the system works.
  • Describe implementation of threads and processes on SmartOS.
  • Describe what happens during thread switching.
  • Describe what happens during interrupt handling.
  • Explain how memory management is implemented on X64.
  • Use the SmartOS thread scheduling classes.
  • Explain how signals are handled in SmartOS.
  • Describe file system implementation, both in-memory and on-disk.

Prerequisites

Basic knowledge of Operating System concepts will help, as well as a basic understanding of programming languages. Unix fundamentals course or equivalent knowledge
