Disaster Recovery Using VVR 4.3 and Global Cluster Option (VCS 4.3) for Windows

Overview:

The Symantec Disaster Recovery Using VVR 4.3 and Global Cluster Option (VCS 4.3) for Windows course is designed for administrators who are responsible for implementing and managing Windows clusters across multiple sites using VVR as the data replication method. This five-day, instructor-led, hands-on class covers the fundamentals of data replication and planning, implementing, and managing the Volume Replicator component of your disaster recovery strategy. You learn how to use Volume Replicator in cluster environments, together with Cluster Server, for disaster recovery purposes.

Description:

Course Objectives
By the end of this course, you should be able to:
• Describe concepts and components that are specific to VERITAS Volume Replicator.
• Implement VERITAS Volume Replicator.
• Initialize, synchronize, and replicate data.
• Perform a takeover, a migration, and a failback.
• Describe how VCS supports replication.
• Configure a global cluster using the VCS Global Cluster option.
• Manage a global cluster environment, including remote clusters, global heartbeats, and global
service groups.
• Configure notification and failover behavior in a global cluster.
• Implement and manage replication in a global cluster.
• Perform off-host processing under VCS control.
• (Optional) Implement a replicated data cluster.

Who Should Attend
This course is for VCS administrators who are responsible for implementing and managing Windows clusters across multiple sites using VVR as the data replication method.

Prerequisites
You should have working knowledge of Windows system administration and configuration. Completion of the Storage Foundation for Windows and Cluster Server for Windows courses, or equivalent experience on each product, is required.

Hands-On
This course includes practical exercises that enable you to test your new skills and begin to transfer them into your working environment.
