Patent number: 10152230Abstract: Replication techniques for file-based replication. A first file pool and a second pool may be created, respectively, on a first site and a second site. Storage for the first file pool may be provisioned from a first storage device group configured as a first consistency group. Storage for the second file pool may be provisioned from a second storage device group configured as a second consistency group. Modification operations, such as writes, may be applied to the first file pool. The modifications performed on the first file pool result in corresponding modifications to the first consistency group. The modifications may be replicated on the second file pool by applying the modifications to the second consistency group. File systems created in the first and second file pools may be self-contained and modifications applied to the first and second consistency groups may be applied in a specified order to ensure write consistency.Type: GrantFiled: September 27, 2016Date of Patent: December 11, 2018Assignee: EMC IP Holding Company LLCInventors: Tianfang Xiong, Yuanyang Wu, Yifeng Lu, Minghui Zhang, Hongru Xu

Patent number: 10146649Abstract: A technique handles a VDM failover situation. The technique involves adjusting a configuration file on a first platform to indicate whether data managed by an initial VDM on that platform is being replicated to a second platform. The technique further involves, following a VDM failover event, creating a replacement VDM on the first platform to replace the initial VDM. The technique further involves, after the replacement VDM is created, performing an operation that controls interfaces provided by the replacement VDM. The operation enables the interfaces when the operation determines that the data managed by the initial VDM on the first platform was not being replicated to the second platform at the time of the event, and disables the interfaces when the operation determines that the data managed by the initial VDM on the first platform was being replicated to the second platform at that time of the event.Type: GrantFiled: September 26, 2017Date of Patent: December 4, 2018Assignee: EMC IP Holding Company LLCInventors: Minghui Zhang, Tianfang Xiong, Yuanyang Wu, Yifeng Lu, Hongru Xu

Patent number: 10085481Abstract: An electronic cigarette or vaporizer may include a shell and a cartomizer receivable within a chamber within a portion of the shell. The cartomizer may hold a vaporizable fluid, dry substance, or other vaporizable substance such as a wax. A charger may also be included which in one embodiment may be insertable into the chamber, and in another embodiment may be connectable to an end of the shell. Various electrical components, such as a printed circuit board, a recharagable battery, various indicator lights, a sensor, and display screen, for instance, improve the functionality of the vaporizer from known vaporizers. Magnets may also be provided in order to secure the cartomizer or the charger to the shell.Type: GrantFiled: November 12, 2014Date of Patent: October 2, 2018Assignee: VMR Products, LLCInventors: Jan Andries Verleur, Dan Recio, Yifeng Lu, Yinjun Zhang, Arturo Fajardo, Hans Verleur

Patent number: 10007567Abstract: There is provided a method and device for recovering data replication between storage devices. The method comprises: creating mirrored pairs between logical units of a primary storage device and logical units of a secondary storage device; in response to the primary storage device recovering from an interruption state to a normal state, re-creating the mirrored pairs based on one or more replication sessions between the logical units of the primary storage device and the logical units of the secondary storage device stored before interruption; and replicating data to the primary storage device based on the re-created mirrored pairs.Type: GrantFiled: December 23, 2016Date of Patent: June 26, 2018Assignee: EMC IP Holding Company LLCInventors: Alex Minghui Zhang, Brian Tianfang Xiong, Yuanyang Wu, Yifeng Lu, Sherry Hongru Xu

Publication number: 20180144042Abstract: Techniques are described herein for automatically generating data extraction templates for structured documents (e.g., B2C emails, invoices, bills, invitations, etc.), and for assigning classifications to those data extraction templates to streamline data extraction from subsequent structured documents. In various implementations, a data extraction template generated from a cluster of structured documents that share fixed content may be identified. Features of the cluster of structured documents may be applied as input to extraction machine learning model(s) trained to provide location(s) of transient field(s) in structured documents, to determine location(s) of transient field(s) in the cluster of structured documents. An association between the data extraction template and the determined transient field location(s) may be stored. Based on the association, data point(s) may be extracted from a given structured document of a user that shares fixed content with the cluster of structured documents.Type: ApplicationFiled: November 23, 2016Publication date: May 24, 2018Inventors: Ying Sheng, Yifeng Lu, Jing Xie, Jie Yang, Luis Garcia Pueyo, Jinan Lou, James Wendt

Publication number: 20170269859Abstract: The present disclosure provides a method and an apparatus for a storage system. The storage system includes an active storage site and a standby storage site, and a logical unit number LUN for a storage pool of the active storage site is replicated to a LUN for a storage pool of the standby storage site to form a consistency group. The method comprises: creating a first LUN and a second LUN as mirrors of each other at the active storage site and the standby storage site, respectively; adding the mirrors formed by the first LUN and the second LUN to the consistency group; after the second LUN is added to the storage pool of the standby storage site, adding the first LUN to the storage pool of the active storage site.Type: ApplicationFiled: March 16, 2017Publication date: September 21, 2017Inventors: Sherry Hongru Xu, Brian Tianfang Xiong, Yifeng Lu, Alex Minghui Zhang, Luna Yue Kuang
