RH436 - Red Hat Enterprise Clustering and Storage Management

Course Summary

RH436 Red Hat Enterprise Storage Management provides intensive hands-on experience with Red Hat Cluster Suite and Global File System™ (GFS). This 4-day course focuses on the implementation of high-availability (failover) services in a clustered computing environment, and on providing an enterprise-class shared filesystem on modern equipment typically found in corporate machine rooms. The final day of class provides additional lab time so that course participants have ample time to practice Cluster Suite and GFS skills in a realistic environment before returning to production systems.
