Systems, methods and computer program products for supporting transformation to a shared on-demand infrastructure
View Patent ↗Systems, methods and computer program products for supporting transformation to a shared on-demand infrastructure. Exemplary embodiments include a method including identifying a CPU resource type (or, in general, other sharable resource) to analyze, calculating a number of servers in scope, Ns, collecting current resource usage data for systems in the scope, wherein the current resource data is provided by systems and performance management tools, identifying a Period P, counting a number of peaks (Np) in the Period, excluding adjacent spikes to each of the number of peaks, calculating an average of CPU usage, Um, which is generally provided by the usage collection tools, defining an amplitude Am, defining a value for % Ks, in the range of 0.2-0.3 (value suggested) and applying transformation formulas to obtain a minimum size of a resource pool, a size of a target environment and a resource saving.
1. In a computer system, a method for transformation to a shared on demand infrastructure, the method comprising:
identifying a sharable resource including at least one of a CPU resource type to analyze;
calculating a number of servers in scope, Ns;
collecting current resource usage data for systems in the scope, wherein the current resource data is provided by systems and performance management tools;
identifying a Period P;
counting a number of peaks, Np, in the Period, excluding adjacent spikes to each of the number of peaks;
calculating an average of CPU usage, % Um, which is generally provided by the usage collection tools;
defining an amplitude Am;
defining a spare resources value for % Ks, in the range of 0.2-0.3; and
applying transformation formulas to obtain a minimum size of a resource pool, a size of a target environment and a resource saving,
wherein a transformation formula to calculate the minimum size of the resource pool, % MinPoolSize, is:
