xCAT (Extreme Cloud Administration Toolkit) is an open source tool designed to automate the deployment, scaling, and management of bare metal servers and virtual machines. It offers comprehensive management capabilities for high-performance computing clusters, render farms, grids, web farms, online gaming infrastructures, clouds, and data centers. xCAT provides an extensible framework based on years of system administration best practices, enabling administrators to discover hardware servers, execute remote system management, provision operating systems on physical or virtual machines in both disk and diskless modes, install and configure user applications, and perform parallel system management. The toolkit supports various operating systems, including Red Hat, Ubuntu, SUSE, and CentOS, and is compatible with architectures such as ppc64le, x86_64, and ppc64. It integrates with management protocols like IPMI, HMC, FSP, and OpenBMC, facilitating remote console access.
