Patent ID: 8051162

Claim:
A method for data assurance in server consolidation, comprising: collecting performance data of a plurality of source servers in a desired environment that are selected for server consolidation, the performance data includes an input trace of each of the plurality of source servers, the input trace includes data of a plurality of performance metrics collected over a predetermined period of time at predetermined time intervals for the each performance metric; evaluating and checking a data structure of the input traces of the collected performance data, wherein the checking includes checking for missing data in the data structure of the input traces; applying with a computerized system predetermined time stamps, predetermined checks, and predetermined statistic computations to each of the input traces; generating, based on results of applying predetermined time stamps, predetermined checks, and predetermined statistic computations, data to fill in the missing data of at least one of the input traces; and evaluating a data quality of the input traces based on the generated data.
