Enterprise Linux High Availability Clustering

Catalog Home UNIX/Linux & Perl UNIX & Linux

This is an in-depth course that focuses on two key areas, Linux high availability (HA) clustering and HA storage administration. Storage is integral to many HA clusters so as to make use of clustered storage technologies to enable active/active configurations. Over the course of many in-depth lab exercises, each student will assemble a realistic three-node Linux cluster utilizing best practices. Each node has three network interfaces and each student's cluster has its own dedicated cluster VLAN. The class contains a storage array for shared LUNs among the nodes. This enables students to perform very real world tasks in a real world setting, including multipathing, redundant ring communication, last man standing cluster, and shared storage scenarios. Course topics include: Cluster Architecture & Design, Pacemaker, Corosync, Fencing, Resource Management, Advanced Resource Management, Multipathing, Cluster LVM, Global File System v2. The unprecedented real-world nature of this class requires a classroom configuration that would be daunting (but not impossible) to put together in a physical or virtual classroom. The online classroom solution, instantly and easily deploys a classroom with the exact configuration needed to support this class. Students will be able to focus on the course topics rather than configuration settings outside the scope of the course. Current Version: E02

This course requires an advanced knowledge of Linux system administration. These skills are taught in the "Enterprise Linux Systems Administration" course and the "Linux Fundamentals" course.
