Consolidation through

Virtualization with the Sun x64 Server Product Line < Today’s IT organizations are being asked to perform a nearly-impossible juggling act. Deliver more applications but at lower cost. Increase performance but reduce the number of systems to manage. Buy the best server for the job but maintain the flexibil- ity to change which operating systems you support at a moment’s notice. Support Microsoft Windows today, the Solaris™ Operating System tomorrow, and keep your Linux skills well-honed. Fortunately, Sun has a solution that helps increase flexibility and reduce risk. With Sun Fire™ x64 servers powered with AMD Opteron™ processors, you can choose which enterprise operating system to run today — Solaris, Windows, Linux — and change your mind tomorrow. But consoli- date multiple applications and different operating systems onto the same server? It’s an innova- tive way to do more with less, and it’s straightforward with virtualization technologies available from Sun and its partners (Figure 1).
