RHEL Clustering and Storage Management. 5 Days

Transcription

1 QWERTYUIOP{ RHEL Clustering and Storage Management 5 Days This hands on course covers the high availability clustering and storage management technologies found in Red Hat Enterprise Linux 6+. Each student is assigned 3 dedicated machines and builds a cluster that conforms to industry best practices and offers a variety of services. Students configure their cluster with multipath connections to iscsi SAN storage and use clvm and GFS2. Clusters are configured and managed using both GUI and command line tools. Cluster configuration includes advanced topics such as dual-ring Corosync, failover domains, and QDisk with heuristics. Prerequisites: This course requires an advanced knowledge of Linux system administration. These skills are taught in the GL120 Linux Fundamentals and GL250 Enterprise Linux Systems Administration. Supported Distributions: Red Hat Enterprise Linux 6 Recommended Class Length: 3 days Detailed Course Outline: 1. INTRODUCTION TO CLUSTERING AND STORAGE MANAGEMENT 1. Clustering Introduction 2.
