What is "quattor"

Quattor is a generic open-source tool-kit used to install, configure, and manage computers. Quattor was originally developed in the framework of European Data Grid project (2001-2004). Since its first release in 2003, Quattor has been maintained and extended by a volunteer community of users and developers, primarily from the community of grid system administrators. The Quattor tool-kit, like other configuration management systems, reduces the manpower required to maintain a cluster and facilitates reliable change management. However, three unique features make it particularly attractive for managing grid resources:

• Federated Management: The open, modular nature of the tool-kit permits system administrators at different institutes to share the management of their distributed resources.
• Shared Configuration and Management Efficiency: Quattor encourages the re-use of configuration information in such a way that it can be distributed and used with little or no modification at different sites, facilitating the distribution of best practices without the need for each site to implement configuration changes.
• Coherent Site Model: Quattor allows an administrator to develop a site model that, once constructed, can be used to manage a range of different resources, such as real machines, virtual machines and cloud resources.

These features are also attractive beyond the grid context. This has been confirmed by the growing adoption of Quattor, by both large commercial organisations and academic institutions, most of them using the tool-kit to manage consistently their grid and non-grid systems.

Quattor was a Brazilian petrochemical company headquartered in Rio de Janeiro. Founded on June 12, 2008, Quattor was the second largest petrochemicals in Brazil, behind only the Braskem and one of the largest petrochemical of the Americas. In 2009 the company was incorporated by Braskem, the largest Brazilian petrochemical and one of the largest in the world.

Quattor was result of the union of assets UNIPAR(60%) and Petrobras(40%), and now the set of five companies, Quattor Participações SA, Quattor Basic Chemicals SA (ex-Union Petrochemical SA), SA Quattor Petroquímica (formerly Suzano Petroquímica SA), Polyethylenes Union SA and Rio Polímeros SA.

The company has 11 production units located in three Brazilian states: Rio de Janeiro, São Paulo and Bahia, in addition to the support office in São Paulo. It also has laboratories Quality and Development Centers, which assist in the development and improvement of its products. All this facilities have been transferred to Braskem.
