Red Hat High Availability Clustering with Exam (RH437)

Gain a better understanding of storage management, Red Hat Cluster Suite, and the shared storage technology delivered by Red Hat Global File System (GFS).

GK# 1232 Vendor# RH437

Course Overview


Created for senior Linux® system administrators, this four-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.

This course also helps you prepare for the Red Hat Certificate of Expertise in High Availability Clustering exam (EX436).  This version of the course includes the exam.

This course is comprised of RH436  and EX436. If you are not looking for private group training, the updated schedule for this course can be found on the Title RH436 page or call your training advisor for more information.

Note: Global Knowledge and Red Hat do not guarantee that anyone who takes one or all of the courses in the Red Hat certification program will pass a Red Hat exam. On-the-job experience, in combination with high-quality training, is the best way to build skills and prepare for a Red Hat exam. The exam itself is a hands-on learning experience, and many of those who do not pass on the first try come away with knowledge of what they need to work on to pass the exam on a re-take.


Upon passing the exam, you'll receive a Certificate of Expertise for Clustering Storage Management. This exam is one of three that are required to earn a Red Hat Certified Data Center Specialist (RHCDS) certification and one of five exams needed to earn a Red Hat Certified Architect (RHCA) certification.
