Red Hat High Availability Clustering [RH436]

OVERVIEW

Design and deploy a high availability cluster

Red Hat® High Availability Clustering (RH436) provides intensive, hands-on experience with the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, as well as cluster storage components from the Resilient Storage Add-On, including Cluster Logical Volume Manager (CLVM), Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

This course is based on Red Hat Enterprise Linux 7.1.

Created for senior Linux® system administrators, this 4-day course strongly emphasizes lab-based activities. You'll learn how to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.

OBJECTIVES

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

AUDIENCE

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.

CERTIFICATION

This course helps you prepare for the Red Hat Certified Specialist in High Availability Clustering exam (EX436).  Alternatively you can enroll for the RH437 courses that also includes the EX436 exam.
