Publication number: 20230177017Abstract: The present technology pertains to synchronizing contents of a directory external to a synchronized directory by a content management system. The content management system is configured to synchronize only objects in the synchronized directory. Accordingly, the present technology creates an anchor object that represents the directory external to the synchronized directory within the synchronized directory. The anchor object includes special attributes that indicate to the synchronization client that the anchor object represents an external directory, and allows the contents of that directory to be synchronized directly to a server on the content management system without first storing the contents of the external directory on the hard drive of the client device.Type: ApplicationFiled: February 3, 2023Publication date: June 8, 2023Inventors: Sourabh Yerfule, Parker Timmerman, Adam Arbree, Pranav Vishnu Ramabhadran, Zihao Yang, Lisa Fan, Kelson Reiss, Geoffry Song, Nipunn Koorapati

Publication number: 20230094648Abstract: The present technology is directed to providing a backup service utilizing a bi-directional synchronization architecture. In order to support both a backup service and a bi-directional synchronization service, the present technology can utilize a special object called an anchor that only permits unidirectional synchronization. Additionally, the present technology separates the backup service from the bi-directional synchronization service. This separation includes utilizing a separate backup directory and bi-directional synchronization directory on a client device, which in turn benefits from the use of a separate instance of the synchronization service on the client device. Further, at the content management system various steps are taken to separate the backup directory from the bi-directional synchronization directory to ensure no objects from the backup directory appear in a user interface related to bi-directional synchronization, and vice versa.Type: ApplicationFiled: September 30, 2021Publication date: March 30, 2023Inventors: Sourabh Yerfule, Kelson Reiss, Jordi Paris Ferrer, Adam Arbree, Geoffry Song

Publication number: 20220188273Abstract: Technologies for implementing customized behaviors for content items are provided. An example method can include receiving, from a user account registered with a content management system, a request to access a content item managed by the content management system for the user account, the content item having one or more behaviors configured for an attribute associated with the content item and/or the content item associated with the attribute; obtaining, from a representation of a remote state of content items associated with the user account, metadata defining the attribute associated with the content item; based on the metadata, determining the one or more behaviors configured for the attribute and/or the content item associated with the attribute; and applying the one or more behaviors to the content item.Type: ApplicationFiled: December 14, 2020Publication date: June 16, 2022Inventors: Nipunn Koorapati, Pranav Vishnu Ramabhadran, Gautam Gupta, Adam Arbree, Michael Nilsson, Parker Timmerman, Stanimir Pehlivanov, Sourabh Yerfule, Yuyang Guo, Bryan Guillemette, Zihao Yang, Rishabh Jain, Jonathan Chien, Royce Ausburn, David Aeschlimann

Patent number: 10768823Abstract: Methods, systems, and programs are presented for controlling the flow of data into a device in the presence of writes that are unaligned along boundaries associated with a block size. One method includes operations for identifying admission data rates for volumes, and for tracking a utilization rate of a memory that stores data of incoming writes. The method determines if incoming writes include unaligned data. When the memory utilization rate is above a first threshold, a first flow control is applied that includes a reduction of admission rates of volumes having unaligned writes while maintaining admission rates of volumes without unaligned writes. When the utilization rate is above a second threshold that is greater than the first threshold, a second flow control is applied in addition to the first flow control. The second flow control includes a reduction of a system admission rate for all incoming writes.Type: GrantFiled: April 12, 2016Date of Patent: September 8, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Gurunatha Karaje, Mandar Samant, Sourabh Yerfule, Zhaosheng Zhu, Vanco Buca

Patent number: 10545791Abstract: Methods for scheduling operations in a scheduler hierarchy of a storage system. One method includes scheduling a first IO having a first cost at a first flow scheduler of a first flow configured to schedule IOs accessing a volume as executed on a first core processor. A global cost is updated with the first cost, wherein the global cost is shared by a plurality of flows of a plurality of core processors. An intervening cost is determined of at least one IO possibly scheduled before the first set of IOs by one or more flow schedulers of one or more flows configured to schedule IOs accessing the volume as executed on the plurality of core processors. A current cost is updated based on the first cost and the intervening cost. IOs and MBPS limits are set independently for the volume, each controlling scheduling through a corresponding accumulating current cost.Type: GrantFiled: January 20, 2017Date of Patent: January 28, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Sourabh Yerfule, Gurunatha Karaje, Mandar Samant, Sagar Trehan

Patent number: 10394606Abstract: Methods and systems are presented for allocating resources based on dynamic weight accumulation performed in a bottom-up fashion in a scheduler hierarchy of a storage system. One method includes assigning weights to leaf schedulers at a bottom level of schedulers in a scheduler hierarchy comprising a plurality of levels of schedulers. Between two levels, each parent scheduler is associated with a unique plurality of children schedulers. For each leaf scheduler that is active, the method includes propagating a corresponding weight of a corresponding leaf scheduler to every higher level in the scheduler hierarchy, such that a corresponding scheduler at a corresponding level is associated with an accumulation of weights of its descendent schedulers. The method includes distributing resources assigned to the scheduler hierarchy based on accumulated weights at each level, such that the corresponding scheduler is proportioned resources based on the accumulation of weights of its descendent schedulers.Type: GrantFiled: September 20, 2016Date of Patent: August 27, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Sourabh Yerfule, Mandar Samant, Gurunatha Karaje

Patent number: 10387051Abstract: Examples include acquisition of IOPS limits and MBPS limits independently at a parent scheduler in a scheduler hierarchy of a storage system, wherein the scheduler hierarchy includes a parent level and a child level below the parent level. Examples include setting IOPS limits and MBPS limits independently at each child scheduler placed within the child level of the scheduler hierarchy. Examples include receiving a CPU resource allocation at the parent scheduler, wherein the CPU resource allocation is convertible to an IOPS allocation at the parent scheduler. Example include distributing the IOPS allocation among the child schedulers below the parent scheduler such that each of the child schedulers receive the same distribution of the IOPS allocation. Example include allocating IOPS between the child schedulers based on their corresponding IOPS limits.Type: GrantFiled: August 24, 2017Date of Patent: August 20, 2019Assignee: Hewlett Packard Enterprise Development LPInventors: Sourabh Yerfule, Gurunatha Karaje, Mandar Samant, Sagar Trehan
