Patent number: 9237131Abstract: A method for providing virtual private storage array (VPSA) service for cloud users over a computer network includes receiving parameters for the VPSA over the network and creating the VPSA from resources of server computers. Creating the VPSA includes allocating and exposing drives that meets or exceeds specified drive characteristics, drive quantity, and array redundancy criteria to virtual controllers (VCs) in the VPSA, and dedicating parts of processor/memory complexes that each meets or exceeds a specified virtual controller hardware model to the VCs. The VCs run on virtual machines on the dedicated parts of processor/memory complexes on independent server computers. The VCs discover the exposed drives, create a virtual pool from the exposed virtual drives, implement data protection on the virtual pool, create volumes from the virtual pool, expose the volumes over the network to a customer computer, and handle access requests to the volumes from the customer computer.Type: GrantFiled: July 22, 2014Date of Patent: January 12, 2016Assignee: Zadara Storage, Ltd.Inventors: Nelson Nahum, Yair Hershko, Yoav Ossia, Shyam Kaushik V., Lev Vainblat, Alex Lyakas, Moshe Melnikov, Vladimir Popovski

Patent number: 8356148Abstract: Methods and systems for improving performance in a storage system utilizing snapshots are disclosed by using metadata management of snapshot data. Specifically, various metadata structures associated with snapshots are utilized to reduce the number of IO operations required to locate data within any specific snapshot. The number of IO operations are reduced by allowing the various metadata structures associated with the temporally current snapshot to locate data directly within any temporally earlier snapshot or on the original root volume.Type: GrantFiled: September 22, 2009Date of Patent: January 15, 2013Assignee: LSI CorporationInventors: Vladimir Popovski, Nelson Nahum, Alexander Lyakas, Ishai Nadler, Moshe Melnikov

Patent number: 8239653Abstract: Methods and apparatuses are provided for active-active support of virtual storage management in a storage area network (“SAN”). When a storage manager (that manages virtual storage volumes) of the SAN receives data to be written to a virtual storage volume from a computer server, the storage manager determines whether the writing request may result in updating a mapping of the virtual storage volume to a storage system. When the writing request does not involve updating the mapping, which happens most of the time, the storage manager simply writes the data to the storage system based on the existing mapping. Otherwise, the storage manager sends an updating request to another storage manager for updating a mapping of the virtual storage volume to a storage volume. Subsequently, the storage manager writes the data to the corresponding storage system based on the mapping that has been updated by the another storage manager.Type: GrantFiled: April 23, 2009Date of Patent: August 7, 2012Assignee: Netapp, Inc.Inventors: Vladimir Popovski, Ishai Nadler, Nelson Nahum

Patent number: 8224781Abstract: Systems and methods herein provide for protecting data using snapshots and images of those snapshots to quickly recreate data upon request. For example, a storage controller of a data storage system allocates a period of time between creating snapshots of data in a first storage volume of the data storage system. The controller then logs received write requests to the first storage volume and generates snapshot of data in the first storage volume based on the allocated period of time. Thereafter, the controller may receive a request to recreate data. The controller locates the snapshot in the first storage volume based on that request to recreate the data. In doing so, the controller generates a snapshot image in a second storage volume. The controller then retrieves logged write requests and applies them to the snapshot image to recreate the data in the second storage volume.Type: GrantFiled: May 14, 2010Date of Patent: July 17, 2012Assignee: LSI CorporationInventors: Vladimir Popovski, Nelson Nahum

Patent number: 8131688Abstract: Data segments are logically organized in clusters in a data repository of a data storage system. Each clusters contains compressed data segments and data common to the compression of the segments, such as a dictionary. In association with a write request, it is determined in which of the clusters would the data segment most efficiently be compressed, and the data segment is stored in that data cluster.Type: GrantFiled: August 26, 2009Date of Patent: March 6, 2012Assignee: LSI CorporationInventors: Vladimir Popovski, Nelson Nahum

Patent number: 8051050Abstract: Data segments are logically organized in groups in a data repository. Each segment is stored at an index in the data repository. In association with a write request, a hash algorithm is applied to the data segment to generate a group identifier. Each group is identifiable by a corresponding group identifier. The group identifier is applied to a hash tree to determine whether a corresponding group in the data repository exists. Each existing group in the data repository corresponds to a leaf of the hash tree. If no corresponding group exists in the data repository, the data segment is stored in a new group in the data repository. However, if a corresponding group exists, the group is further searched to determine if a data segment matching the data segment to be stored is already stored. The data segment can be stored in accordance with the results of the search.Type: GrantFiled: July 16, 2009Date of Patent: November 1, 2011Assignee: LSI CorporationInventors: Vladimir Popovski, Nelson Nahum
