HPE Performance Cluster Management Foundations (H8PE8S)

The HPE Performance Cluster Manager (HPCM) Foundations course provides knowledge and practice in cluster operation areas such as navigating the HPCM graphical user interface (GUI), monitoring cluster components, operating system boot modes and root filesystem modes, cluster power management, running commands on multiple servers, connecting to server consoles, and backing up the cluster configuration.
