Red Hat High Availability Clustering – RH436

Design and deploy a high availability cluster.

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, as well as 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.

Što ćete naučiti

  • Improve application uptime by using high availability clustering
  • Manage storage in an high availability environment using iSCSI initiators, HA-LVM or CLVM as appropriate, and GFS2 cluster file systems
  • Implement strategies to identify single points of failure in high availability clusters and eliminate them

Kome je namijenjeno

Senior Linux system administrators responsible for maximizing resiliency through high-availability clustering services and using fault-tolerant shared storage technologies.

Preduvjeti

Red Hat Certified System Administrator (RHCSA) certification or an equivalent level of knowledge is highly recommended.
