Red Hat RH436 Course Overview
Vinsys authorized Red Hat Clustering course describes how to provide highly available network services to a mission-critical enterprise environment through the deployment/management of shared storage and server clusters. In addition, it lets you 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 like web servers and databases on that cluster.
The in-depth training covers cluster storage components from the Resilient Storage Add-On, ensuring the installations and applications requiring multiple cluster nodes can access the same storage simultaneously. It includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.
Our Red Hat RH436 course also prepares you for the EX436 exam, necessary for securing the Red Hat Specialist in High Availability Clustering accreditation.
