It provides powerful, portable and modular tools for the automated installation, configuration and management of clusters, grids and clouds running UNIX-like operating systems such as Linux. At ... [More] its heart, sits a powerful language, Pan, for describing configuration. It can be used to manage non-grid servers, desktops, virtual machines and much more. Developed to manage the clusters and services used in grid computing, Quattor is today being used to manage many separate infrastructures worldwide. From massive single-sites such as CERN to highly-distributed multi-site infrastructures such as Grid-Ireland and a few very large commercial companies operating hundreds of thousands of nodes.

This helps to centralize all file system access, provide a uniform site-wide namespace, and minimize downtimes for clients. The ... [More] Berkeley Automounter, Amd, may be used as a replacement for Sun's automounter. The choice of which file system to mount can be controlled dynamically with selectors. Selectors allow decisions of the form "hostname is this," or "architecture is not that." Selectors may be combined arbitrarily. Amd also supports a variety of file system types [Less]
