Red Hat RH437 Course Overview

Vinsys' authorized Red Hat High Availability Clustering training explains providing highly available network services to a mission-critical enterprise environment through the deployment/management of shared storage and server clusters. Moreover, it allows you to set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services, including web servers and databases. 

The in-depth course takes you through all the cluster storage components from the Resilient Storage Add-On, ensuring the installations/applications requiring multiple cluster nodes can access the same storage simultaneously. It comprises Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath. 

Our Red Hat training also prepares you for the Red Hat Specialist in High Availability Clustering EX436 exam.
