Red Hat Enterprise Clustering and Storage Management

The Red Hat Enterprise Clustering and Storage Management Exam is a performance-based test of the skills covered in RH436 Red Hat Enterprise Clustering and Storage. The RH436 course delivers extensive hands-on training with storage management, Red Hat Cluster Suite, and the shared file system, GFS. Thereby, students earn the skills required to deploy and manage highly available storage data to the mission-critical enterprise computing environment.

In order to enrol in this exam, one must have an RHCE on a current release at the time of the exam. Upon passing the exam, one will have earned this additional Certificate of Expertise to one’s RHCE certification.

Counts towards RHCA and RHCDS certifications

This Certificate of Expertise is one of five required to earn the designation Red Hat Certified Architect (RHCA) and one of the three required in order to earn the designation Red Hat Certified Datacentre Specialist (RHCDS).

Red Hat Enterprise Clustering and Storage Management

Red Hat Enterprise Clustering and Storage Management (RH436) provides intensive, hands-on experience with storage management, Red Hat Cluster Suite, and the shared storage technology delivered by Red Hat Global File System (GFS). Created for Senior Linux system administrators, this 4-day course has a strong emphasis on lab-based activities using enterprise-class storage, server, and auxiliary equipment. 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.


  • Experienced Linux system administrators responsible for managing shared storage across one or more Linux systems
  • Experienced Linux system administrators responsible for maintaining a high availability service using cluster technology


  • Red Hat Certified Engineer (RHCE) certification or equivalent experience
  • Students without an RHCE certification are encouraged to do a skills assessment online

Certification Examination

The EX436 Clustering and Storagement Management Expertise Exam tests the ability of an RHCE to implement high-availability clustering, logical volume management, and GFS filesystems for enterprise environments.

Exam Format

The format is performance-based, meaning that candidates must perform tasks on live systems, rather than answering questions about how one might perform those tasks.


Candidates must be an RHCE on a release that is considered current in order to take this exam.

Components of the Exam

The exam is organised as follows:

  • Clustering and Storage Management: 4.0 hours

Duration: 4 Hours

Fee: Rs 12,500/- + service tax

Exam Objectives

Candidates should be able to perform the tasks listed below:

  • Configure a high-availability cluster, using either physical or virtual systems, that
    • provides a service fail-over between the nodes
    • provides a preferred node for the service
    • selectively fails over based on node characteristics
  • Configure a GFS filesystem to
    • meet specified size, layout, and performance objectives
    • support filesystem quotas
  • Configure SNMP to provide cluster monitoring
  • Configure iSCSI targets and initiators.
  • Manage software RAID and LVM to provide
    • metadevices of specified RAID type, size, and characteristics
    • monitoring and notification of RAID status
    • LVM snapshots

As with all Red Hat performance-based exams, configurations must persist after reboot without intervention.
