Quattor is a large scale fabric management system for managing medium to very large (>1000 node) clusters. It is largely similar to LCFG and is particularly well suited to Grid computing sites. Quattor was developed at CERN for use in the LCG project. Quattor is in used by many Grid sites around the world today.
A Grid site will use profiles to configure machines (virtual and physical) using a language called PAN, this is then compiled using panc and ant, and creates XML profiles, which the NCM (node configuration manager) on each machine uses to configure the machine. Typical configuration includes software package installation and machine settings (grub for instance).
