“We’ve seen very strong demand for System z for both traditional workloads and Linux workloads.” —Karl Freund The Data Center,” by the research firm Robert Frances Group, found when one company consolidated hundreds of UNIX* servers to one System z server, the company estimated it would save $350,000 annually in power costs; showing monthly power costs for the UNIX servers came in at of $30,165 versus $905 for the mainframe. In addition to offering energy-cost savings, virtualization on the System z platform, which has been around for many years, also allows for quicker server deployments. Instead of sizing, purchasing and deploying a stand-alone machine, a virtual server can be quickly built on the System z hardware, bringing more resources under one umbrella to make the entire IT infrastructure much easier to manage and cheaper to operate. This type of System z platform-based scaling out offers many benefits. For example, System z users who take advantage of z/VM* can more easily provision resources across their integrated server environment. The resource-management facilities of z/VM are able to move resources between virtual partitions to where they’re needed, when they’re needed (For more information on z/VM, see “Securing a Virtual World,” page 32). This is in stark contrast to distributed-computing environments, where server utilization might be near 100 percent on one box and well below 10 percent on another. The System z solution can offer near 100-percent utilization through shared resources that are dependent on workload requirements. A Sound Foundation Some System z users scale up with more processors than they need up front, with some activated and some inactivated. If these users need to tap into the inactive processors for whatever reason, they can simply contact IBM to authorize the additional processors. Additionally, all of this is done non-disruptively and dynamically, with no need to take the system offline. Similarly, IBM offers “pay for what you use” software capabilities. Rather than paying software charges related to the total capacity of their servers, System z users pay software charges that correspond to their typical peak-capacity usage. When they need extra capacity to meet unusual workload spikes, only then would they pay extra. IBM variable software charges for capacity for the period in which it’s used. This flexibility is available even within mixed-OS environments. Many System z users are likely to run not only z/OS*, but also Linux on Integrated Facilities for Linux (IFLs). The dynamic infrastructure accepts and encourages this type of OS mixing and matching, even though each OS has its own particular traits and is likely installed for specific workloads in realworld operating environments. “We’ve seen ver y strong demand for System z for both traditional workloads and Linux workloads,” Freund remarks. “And in some cases, System z customers are using the platform solely for Linux workloads coupled with the database included with System z. This gives them a sound foundation on which to build a dynamic infrastructure.” And with the IBM System z Application Assist Processor (z A A P) available on some System z ser vers, users can deploy and integrate new Java* technology-based workloads on the same platform as traditional mainframe and Linux applications and core business databases.

Any downtime is harmful, with incoming transactions at risk for being lost when servers fail, leaving decision makers with fractured views of their overall business environments. This is especially crucial as end users come to expect a certain level of service. Users’ “right here, right now” data expectations are real, and they have little patience for IT disruptions that impact their decision-making capabilities. And any delay, no matter how momentarily, can significantly disrupt normal business operations. When developing the notion of the dynamic infrastructure, IBM recognized resiliency as a key, if not the vital compo- 44 M AY/J U N E 2 0 0 9 ibms ystemsmag .com/mai nframe
