Overview
The Veritas InfoScale Availability 7.4.2 for Unix/Linux: Administration course is designed for IT professionals tasked with installing, deploying, configuring, and maintaining Veritas Cluster Server (VCS) clusters. This course discusses how to use InfoScale Availability to manage applications in a high availability environment and support for Cloud environments. The course is designed to enable you to gain the necessary fundamental and advanced skills that are required to manage a highly available application in a cluster. It also discusses how to deploy InfoScale Availability in the lab environment to practically implement a sample cluster design and deployment.
Course Objectives
By the completion of this course, you will be able to:
Describe how clustering is used to implement high availability in the data center environment.
Describe VCS and cluster communication mechanisms.
Create a cluster, and configure service groups and resources.
