Abstract: A process includes receiving data representing states of a plurality of nodes of a cluster. The process includes, based on the states, generating data to display, in a text mode on a display device, a plurality of text character status indicators. First text character status indicators are arranged in a first grid that correspond to a physical layout of first nodes in a first computer system rack, and each first text character status indicator represents a status of a corresponding first node.

Abstract: In some examples, a system creates a virtual environment in a computing environment, the virtual environment having a configuration corresponding to a configuration of the computing environment. The system installs, in the virtual environment, a second version of a program while a first version of the program is running in the computing environment, the installing to update the program during a live operation of the computing environment in which the first version of the program is performing a workload.

Abstract: An apparatus includes a chassis; a plurality of nodes that are mounted to the chassis; an electronic paper-based display device that is mounted to the chassis; and a management controller that is mounted to the chassis. Each node is associated with a different operating system instance of a plurality of operating system instances. The management controller, in response to a fault associated with a given node, provides data to cause the electronic paper-based display device to visually display an identity of the given node and information about the fault.
