Hudson Valley Bank was confident that its 2009 server and storage virtualization projects would reap ample benefits, such as slicing data center power consumption in half, a rosy outlook validated by well-schooled local grad students.

The students from Polytechnic Institute of New York University this past spring evaluated energy consumption in different areas of the Yonkers, N.Y.-based bank's data center using metrics such as power usage effectiveness (PUE), according to Andres Fortino, associate provost for corporate graduate programs at Polytechnic Institute in Hawthorne, N.Y. They also analyzed the costs of operating the data center before and after the green IT implementations. This included the investments required to replace 50 underutilized servers with ten newer Dell boxes under the server virtualization project plus the implementation of energy-efficient Dell EqualLogic SAN arrays and an IBM iSeries mainframe and the energy savings from using those devices. "The (students') results were very strong and made us very comfortable about what we were doing," says Howard Bruck, CIO for the $2.4 billion-asset bank.
