Publication number: 20240012714Abstract: Systems, methods, and computer readable storage mediums for performing remote replication including receiving, by a target storage system, an indication that a dataset stored on a source storage system will be replicated to the target storage system; identifying, by the target storage system, portions of the dataset that are not already stored on the target storage system; and initiating, by the target storage system, replication of one or more of the portions of the dataset that are not already stored on the target storage system from a source other than the source storage system.Type: ApplicationFiled: September 22, 2023Publication date: January 11, 2024Inventors: BENJAMIN BOROWIEC, STEVE HODGSON, ETHAN L.

Patent number: 11847336Abstract: A system and method for performing replication using mediums. A snapshot ‘S’ is selected for replication, and the anchor medium ‘M’ of S is identified. The replica storage array ‘R’ to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array ‘O’ and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.Type: GrantFiled: April 29, 2020Date of Patent: December 19, 2023Assignee: PURE STORAGE, INC.Inventors: Ethan Miller, Andrew R. Bernat, John Colgrove, Alan Driscoll, Christopher Golden, Steve Hodgson, Ganesh Ramanarayanan, Malcolm Sharpe

Publication number: 20230359644Abstract: Systems, methods, and computer readable storage mediums for replicating data to the cloud. A first dataset is replicated from a first storage subsystem to the cloud, with only the changes made to the first dataset since a previous replication event being replicated to the cloud. Additionally, the data may be deduplicated and compressed before being replicated from the first storage subsystem to the cloud. In some cases, the first dataset may be replicated to the cloud in a stream format which is not directly usable and then, at a later point in time, loaded onto a second storage subsystem from the cloud.Type: ApplicationFiled: July 14, 2023Publication date: November 9, 2023Inventors: ETHAN L. MILLER, ANDREW R. BERNAT, BENJAMIN BOROWIEC, ALAN S. DRISCOLL, STEVE HODGSON, GANESH RAMANARAYANAN, MALCOLM SHARPE

Patent number: 11561720Abstract: A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being migrated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been migrated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.Type: GrantFiled: April 30, 2021Date of Patent: January 24, 2023Assignee: PURE STORAGE, INC.Inventors: Christopher Golden, Jianting Cao, David Grunwald, Steve Hodgson, Malcolm Sharpe

Patent number: 11561949Abstract: A system and method for efficiently storing data in a storage system. A data storage subsystem includes multiple data storage locations on multiple storage devices in addition to at least one mapping table. A data storage controller determines whether data to store in the storage subsystem has one or more patterns of data intermingled with non-pattern data within an allocated block. Rather than store the one or more pattern on the storage devices, the controller stores information in a header on the storage devices. The information includes at least an offset for the first instance of a pattern, a pattern length, and an identification of the pattern. The data may be reconstructed for a corresponding read request from the information stored in the header.Type: GrantFiled: July 22, 2020Date of Patent: January 24, 2023Assignee: Pure Storage, Inc.Inventors: Marco Sanvido, Richard Hankins, John Hayes, Steve Hodgson, Feng Wang, Sergey Zhuravlev, Andrew Kleinerman

Publication number: 20220413703Abstract: A system, apparatus, and product for allowing access to a partially replicated dataset, including: detecting, by a target storage system, that a dataset will be replicated from a source storage system to the target storage system; exposing, by the target storage system, the dataset for user operations prior to receiving the entire dataset; receiving, by the target storage system, a request to read a portion of the dataset that has not been received by the target storage system; and retrieving, by the target storage system, the portion of the dataset.Type: ApplicationFiled: September 1, 2022Publication date: December 29, 2022Inventors: ETHAN L. MILLER, JOHN COLGROVE, CHRISTOPHER GOLDEN, STEVE HODGSON, MALCOLM SHARPE

Patent number: 11442640Abstract: A system and method for utilizing unmapped and unknown states in a storage system. When a first portion of a first medium is determined to be unreachable from any other mediums, the first portion of the first medium may be put into an unmapped state, and its data may be discarded and the corresponding storage locations may be freed. During replication of the first medium to a replica storage array, the state of the first portion of the first medium may be translated from the unmapped state into an unknown state on the replica storage array. If another storage array has the data of the first portion of the first medium, this data may be used to overwrite the first portion of the first medium on the replica storage array, converting the first portion of the first medium from the unknown state into the mapped state.Type: GrantFiled: October 14, 2020Date of Patent: September 13, 2022Assignee: Pure Storage, Inc.Inventors: Ethan L.

Patent number: 11061786Abstract: Systems, methods, and computer readable storage mediums for generating an alert on a failure of a storage subsystem to phone home to the cloud in a replication environment. A dataset is replicated from a first storage subsystem to a second storage subsystem. The first and second storage subsystems also phone home log data to the cloud on a periodic basis. In response to detecting a failure of the first storage subsystem to phone home, the cloud generates and sends an alert to the second storage subsystem. In response to receiving this alert, the second storage subsystem starts disaster recovery operations for the dataset.Type: GrantFiled: January 31, 2019Date of Patent: July 13, 2021Assignee: Pure Storage, Inc.Inventors: Ethan L.

Patent number: 10430282Abstract: Systems, methods, and computer readable storage mediums for maintaining the history of remapped data in a storage system. A first portion of a first medium may be remapped to a second medium as part of read optimization operations, wherein the second medium is younger than the first medium. A tag associated with the first portion of the first medium may be retained when the first portion is remapped to the second medium. When the second medium is replicated to another storage array, the first portion of the first medium may be prevented from being replicated based on the tag identifying the first portion as being part of a previous replication operation.Type: GrantFiled: October 7, 2014Date of Patent: October 1, 2019Assignee: Pure Storage, Inc.Inventors: Christopher Golden, Malcolm Sharpe, Steve Hodgson
