Editor’s Desk Inside this month’s issue Harry Yudenfriend Photographic memories When he isn’t busy creating technology for IBM, Harry Yudenfriend, author of the Tech Corner article on page 31, can often be found on the court or playing field with a camera around his neck. When his sons started competing in high school varsity sports, Yudenfriend picked up a camera, becoming the unofficial photographer for their teams. He even took his photography skills poolside when his youngest participated in water polo in college. Bob Martus Surf and turf A native of Detroit, Bob Martus, who took this issue’s cover photo, has based his photography business out of Brooklyn, N.Y., for the past 10 years. He enjoys hiking trails throughout the East Coast and surfing the Rockaways in Queens, N.Y. ot since Felix Unger and Oscar Madison became roommates has there been a more odd couple than Linux* and the System z* platform. Running the open-source OS on IBM’s iconic hardware platform was hardly a simple, straightforward decision in 2000. Some felt Linux wasn’t a serious technology and certainly wasn’t something an enterprise should dabble in for mission-critical applications. Many saw it as old school versus new school. What the naysayers didn’t realize was the opportunity for organizations willing to combine the mainframe’s z/VM* capabilities with Linux to create a multitude of virtual servers on a single machine. Suddenly, this odd coupling not only made sense, but it was being called genius. And more than a decade later, the unlikely combination has been an unmitigated success. Adoption of Linux on System z continues to grow at an impressive clip with more than 1,300 Linux clients on the mainframe, notes Greg Lotko, vice president and business line executive for IBM System z, in our cover story on page 20. Implementation is being driven by modern corporate necessities, Lotko explains. These include the need to save money through workload N consolidation, upgrade and scale out on the fly and deliver 24-7 availability. As the Linux on System z environment has grown more popular, usage patterns have evolved as well. Initial efforts focused largely on consolidating simple servers but new uses have emerged as well, such as migrating mission-critical applications and data serving. More on these usage patterns is explained on page 26 in a feature by Ingo Adlung, an IBM Distinguished Engineer in IBM’s Systems and Technology Group, and Dr. Eberhard Pasch, a senior technical staff member in the IBM Linux Technology Center. As Linux on System z continues into its second decade, what was once considered an odd combination is seen as a no-brainer. Who would have guessed penguins were so well adapted for the mainframe habitat?
