HPE Insight Cluster Management Utility (CMU) is an efficient and robust hyperscale cluster lifecycle management framework and suite of tools for large Linux clusters such as those found in High Performance Computing (HPEC) environments. A simple graphical interface enables an 'at-a-glance' view of the entire cluster across multiple metrics, provides frictionless scalable remote management and analysis, and allows rapid provisioning of software to all the nodes of the system. Insight CMU makes the management of a cluster more user friendly, efficient, and error free than if it were being managed by scripts, or on a node-by-node basis. Insight CMU offers full support for iLO2, iLO3, iLO4 and LO100i adaptors on all the ProLiant HPE servers in the cluster.Insight CMU is highly flexible and customizable, offers both GUI and CLI interfaces, and is being used to deploy a range of software environments, from simple compute farms to highly customized, application-specific configurations. Insight CMU is available for HPE ProLiant and HPE BladeSystems, with Red Hat Enterprise Linux and Novell SUSE Linux operating systems, including Red Hat Enterprise Linux, Suse Linux Enterprise, CentOS, and Ubuntu. Insight CMU also includes options for monitoring GPUs and for installing GPU drivers and software.
