About this Course
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, and 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. Created for senior Linux® system administrators, this 4-day course has a strong emphasis on lab-based activities. At the end of the course, students will have learned to deploy and manage shared storage and server clusters that provide highly available network services to a mission-critical enterprise environment.
After attending the course, customers who meet the prerequisites for the Red Hat Enterprise High Availability Clustering course should be prepared to take the EX436 exam.
- Senior Linux system administrators responsible for maximizing resiliency though high availability clustering services and using fault tolerant shared storage technologies.
- An RHCE interested in earning a Red Hat Certification of Expertise or an Red Hat Certified Architect (RHCA).
