SUSE Linux Enterprise 15 High Availability Deployment
This course teaches students to deploy and configure the SUSE Linux Enterprise (SLE) 15 High Availability (HA) product to be ready to deploy workloads. The course introduces the product features and implementation planning for both on premise and public cloud implementations. A SLE15 HA cluster is deployed and then configured to provide corosync network redundancy. Next the fencing configuration is updated which includes adding a quorum arbitrator system. The cluster configuration is then tested before an additional node is added to the existing cluster.
This course prepares students for the SCDS in SUSE Linux Enterprise High Availability exam.
- COD: HAE311v15
- CATEGORY: Linux Enterprise Server
Who should participate
This course is designed for existing Linux administrators who want to deploy a highly availability cluster using the SUSE Linux Enterprise HA Extension. This course provides a foundation for deploying SAP on SLE 15 HA.
Prerequisites
