CUPERTINO, CA--(Marketwire - February 17, 2010) -  Mission West Properties, Inc. (NASDAQ: MSW) and CDH Consulting today announced a new data center property in Oregon that is now available for development. Located in Ontario, Oregon, the site will support a single mission-critical data center facility up to 300,000 square feet, or can allow for three or four smaller data center projects. The site features substantial economic development incentives and some of the lowest power costs in the country.
