The z/OS operating system provides knobs and levers that mainframe professionals can use to limit exposure to excessive MLC Software costs.  But the use of these capabilities is not without risk, and therein lies the dilemma for IT.  IT can set "caps" on LPARs or groups of LPARs and control how many MSUs will be consumed by the work.  But - and this is the concern for many mainframers we've spoken with - limiting the MSU consumption means limiting the workloads that are trying to execute.  If those workloads that get limited are critical business services, the customers, and the business, will not be happy.  To really leverage the capping capability, IT would have to dynamically make changes and then in real time watch what work is trying to execute, so caps can be raised before business service is impacted.  Of course, no one in IT has the time to be doing this.


This is the challenge BMC has addressed with its latest innovative new mainframe solution, BMC Intelligent Capping for zEnterprise.  This solution does what IT would like to do in managing caps - it dynamically adjusts the caps, while being fully aware of the workloads that need to execute to keep the business running properly.  BMC Intelligent Capping, or iCap, employs user-defined policies that identify critical workloads and combines that with a workload-aware view of MSU consumption and capping activity.  The result is a dynamic capping solution that can reduce MLC costs while mitigating risk to critical business workloads.  What could be easier - or safer?
