Abstract: It has been found that a more reasonable estimation of combined workloads can be achieved by enabling the ability to specify the confidence level in which to estimate the workload values. A method, computer readable medium and system are provided for estimating combined system workloads. The method comprises obtaining a set of quantile-based workload data pertaining to a plurality of systems and normalizing the quantile-based workload data to compensate for relative measures between data pertaining to different ones of the plurality of systems. A confidence interval may then be determined and the confidence interval used to determine a contention probability specifying a degree of predicted workload contention between the plurality of systems according to at least one probabilistic model. The contention probability may then be used to combine workloads for the plurality of systems and a result indicative of one or more combined workloads then provided.

Abstract: Compatibility and consolidation analyses can be performed on a collection of systems to evaluate the 1-to-1 compatibility of every source-target pair, evaluate the multi-dimensional compatibility of specific transfer sets, and to determine the best consolidation solution based on various constraints including the compatibility scores of the transfer sets. The analyses can be done together or be performed independently. These analyses are based on collected system data related to their technical configuration, business factors and workloads. Differential rule sets and workload compatibility algorithms are used to evaluate the compatibility of systems. The technical configuration, business and workload related compatibility results are combined to create an overall compatibility assessment. These results are visually represented using color coded scorecard maps.

Abstract: A system and method are provided for determining and visualizing efficiencies and risks in computing environments. The method comprises obtaining resource utilization data and resource capacity data for a plurality of entities in a computing environment; obtaining at least one operational policy defining at appropriate level of at least one resource used by the computing environment according to at least one factor; and computing at least one score quantifying efficiencies and risks associated with the computing environment based on the resource utilization data, resource capacity data, and at least one operational policy.

Abstract: A system and method are provided for incorporating compatibility analytics and virtualization rule sets into a transformational physical to virtual (P2V) analysis for designing a virtual environment from an existing physical environment and for ongoing management of the virtual environment to refine the virtualization design to accommodate changing requirements and a changing environment.

Abstract: It has been recognized that to accurately measure the required resource capacity of computing systems such as servers, various relevant factors should be considered, since the capacity may be excess or insufficient. This measurement can be reflected by the ratio of the theoretical minimum server capacity required relative to the actual server capacity provisioned, hereinafter also referred to as the “fully loaded utilization”, which can be expressed in various ways, including as a percentage or an efficiency index or other number or value.

Abstract: Relationships between systems can be inferred through a correlation analysis of the system workload activity levels. A method, computer readable medium and system are provided for analyzing correlations between the system workloads. The method comprises obtaining a set of quantile-based workload data pertaining to a plurality of systems. The correlation coefficient limit may then be used to compute the workload correlation scores for the plurality of systems and a result indicative of relationships between the systems then provided.

Abstract: Systems and method for performing a consolidation analysis and visually representing the analysis are provided. The analysis is conducted by performing an audit, performing system compatibility and workload compatibility analyses using the audit data and rule sets. The results of the individual analyses are combined to create an overall compatibility co-habitation analysis and visual consolidation roadmap including scorecard information. The system and workload analyses may be performed to contribute to the overall co-habitation analyses, but also performed on their own.

Abstract: A method for evaluating the differences between computer systems is provided. The systems are evaluated using one or more differential rule definitions and one or more differential rule sets. The rules evaluate the differences between specific parameters in the computer systems and are used to generate a score that indicates how different the systems are based on these parameters and preferably what the cost to remedy the difference would be. The rules can be used for consolidation analysis, compliance analysis etc. The rules each include a weight that quantifies the importance of the rule to compatibility and the score is affected accordingly. Systems can be evaluated against each other or against themselves at different instances in time.

Abstract: A system and method for generating statistical reports showing distribution, variance, outliers and trends for parameters across a set of computer systems is provided. The reports are generated based on audited data for each system that pertains to the parameters. A distribution report assesses the uniformity of the parameters of a population of systems and provides frequency distributions and statistics describing the data values from the analyzed systems. A variance report assesses the conformity of one or more target systems against a reference data set comprised of a set of baseline systems. The report compares each target system individually against the reference data set to measure the consistency of the target's parameters. A trend report shows trends in the uniformity and conformity measures of the parameters by comparing the statistical analysis results of sets of systems at two or more points in time or the different systems at the same time.
