Red Hat High Availability Clustering

Experienced Linux system administrators responsible for managing shared storage across one or more Linux systems and Experienced Linux system administrators responsible for maintaining a high availability service using cluster technology.

As a result of attending this course, students should be able to create, manage, and troubleshoot highly available network services and tightly-coupled cluster storage for business-critical applications.

Students should be able to demonstrate the following skills:

• Improve application uptime by using high availability clustering
• Manage storage in an high availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems
• Implement strategies to identify single points of failure in high availability clusters and eliminate them

Following completion of this course you will have the knowledge and experience to:

• Review of Red Hat enterprise clustering and storage management technologies
• Linux dynamic device management
• iSCSI
• Advanced software RAID
• Device mapper and multipathing
