There are a number of projects currently underway to improve and extend the CERN computing facilities which have been reported at previous HEPiX meetings. An update will be given on the current status of these projects and particular emphasis will be placed on efficiency improvements that have been made in the CERN Computer Centre and the resulting energy, and hence cost, savings.

The proposed talk discusses the Deska project [1], our attempt at delivering an inventory database whose goal is to provide a central source of machine-readable information about one's computing center. We mention the motivation behind the project, describe the design choices we have made and talk about how the Deska system could help reduce maintenance effort on other sites.

Mainframes and to a lesser extent VMS hosts were being replaced by Unix hosts with native TCP stacks running on thin and thicknet shared media, the...
