Patent number: 11934678Abstract: In some examples, a system identifies resource contention for a resource in a storage system, and determines that a workload collection that employs data reduction is consuming the resource. The system identifies relative contributions to consumption of the resource attributable to storage volumes in the storage system, where the workload collection that employs data reduction are performed on data of the storage volumes. The system determines whether storage space savings due to application of the data reduction for a given storage volume of the storage volumes satisfy a criterion, and in response to determining that the storage space savings for the given storage volume do not satisfy the criterion, the system indicates that the data reduction is not to be applied for the given storage volume.Type: GrantFiled: July 22, 2022Date of Patent: March 19, 2024Assignee: Hewlett Packard Enterprise Development LPInventors: Manu Sharma, Sudheer Vanapalli, Jaffer Sherif Rajasab, Gautam Kaistha, Manoj Srivatsav, Mayukh Dutta

Patent number: 11643957Abstract: A control module for an aftertreatment system that includes a selective catalytic reduction (SCR) catalyst and an oxidation catalyst, comprises a controller configured to be operatively coupled to the aftertreatment system. The controller is configured to determine an actual SCR catalytic conversion efficiency of the SCR catalyst. The controller determines an estimated SCR catalytic conversion efficiency based on a test sulfur concentration selected by the controller. In response to the estimated SCR catalytic conversion efficiency being within a predefined range, the controller sets the test sulfur concentration as a determined sulfur concentration in a fuel provided to the engine. The controller generates a sulfur concentration signal indicating the determined sulfur.Type: GrantFiled: November 22, 2019Date of Patent: May 9, 2023Assignee: Cummins Emission Solutions Inc.Inventors: Jinqian Gong, Durvesh Ramesh Pathak, Changsheng C.
