Patent number: 11921859Abstract: Methods, systems, and devices for transitioning an information handling system (IHS) to a predetermined operating state is disclosed. During the transition, the IHS may obtain data from a variety of sources which may subject it to compromise. To reduce the likelihood that the IHS is compromised, the IHS may evaluate its environment and its own operation to determine its security state. Depending on its security state, the IHS may perform various actions to reduce the likelihood of it being compromised through its transition process.Type: GrantFiled: November 4, 2021Date of Patent: March 5, 2024Assignee: Dell Products L.P.Inventors: Ibrahim Sayyed, Christopher Channing Griffin, Purushothama Rao Malluru, Chris Edward Pepper

Patent number: 11757648Abstract: Methods and systems for managing the operation of data processing systems are disclosed. A data processing system may include a computing device that may enter various operating states by performing various types of startups. Performance of some startups may be restricted by use of passwords or other security information. The data processing systems may host management controllers that may bypass the restrictions on the startups. Prior to doing so, the management controllers may verify that the requests to perform the startups are from trusted entities, or should be performed for other reasons.Type: GrantFiled: February 9, 2022Date of Patent: September 12, 2023Assignee: Dell Products L.P.Inventors: Christopher Channing Griffin, Adolfo Sandor Montero, Chris Edward Pepper, Purushothama Rao Malluru, Ibrahim Sayyed

Patent number: 10761829Abstract: Methods are disclosed for dynamic node allocation for a server system that can automatically heal on failure—minimizing the need for static configuration—dynamically adjusting server resources to match load, and minimize end user wait times. The disclosed methods dynamically allocate nodes to increase capacity for a platform that accepts data queries. Additionally disclosed is a system for rolling version update deployment: workers maintain org lists of org-task-queues that they service; org-affinities between the workers and the org-task-queues require the workers to have access to local copies of immutable data sets to service org-tasks from the org-task-queues of the orgs that they service. A leader running on a worker implements a healing and balancing service that maintains worker redundancy, manages the workers' org-affinities to accumulate orgs on their respective org-lists. The leader implements messaging to the workers to update to a new software version and monitors completion of updates.Type: GrantFiled: June 12, 2018Date of Patent: September 1, 2020Assignee: salesforce.com, inc.Inventors: Saptarshi Roy, Daniel C. Silver, Donovan A. Schneider, Medha Pradhan, Ryan Lamore, Naveen Purushothama Rao, Nicholas Geh, Srirama Koneru
