Patent number: 9852009Abstract: Methods for optimizing utilization of workload-consumed resources for time-inflexible workloads are disclosed. By sorting workload-consumed resource profiles representing individual workloads in one system according to an order of standard deviation or descending volume, two workload-consumed resource profiles can be combined to check if combination criteria are fulfilled. If any combination satisfies the combination criteria, corresponding workloads can be combined to share the same resource from the system. Thus, optimizing utilization of the workload-consumed resource can be achieved.Type: GrantFiled: May 9, 2016Date of Patent: December 26, 2017Assignee: Prophetstor Data Services, Inc.Inventors: Wen Shyen Chen, Wen Chieh Hsieh, Ming Jen Huang, Tsung Ming Shih
