HP is unveiling a software package based on <A HREF="http://www.eweek.com/article2/0,1895,1950925,00.asp">RLX's Control Tower management software,</A> which was the real target behind the Palo Alto, Calif., company's decision to buy RLX. HP wanted to build up its capabilities of managing Linux environments on its BladeSystems platform, and Control Tower was built on Linux, said Scott Farrand, general manager of HP's Control Tower products group. For example, the HP Control Tower package offers packaged open-source tools for easier use and integration.
