Publication number: 20210303166Abstract: Techniques are provided for object store mirroring. Data within a storage tier of a node may be determined as being data to tier out to a primary object store based upon a property of the data. A first object is generated to comprise the data. A second object is generated to comprise the data. The first object is transmitted to the primary data store for storage in parallel with the second object being transmitted to a mirror object store for storage. Tiering of the data is designated as successful once acknowledgements are received from both the primary object that the first object was stored and the mirror object store that the second object was stored.Type: ApplicationFiled: June 10, 2021Publication date: September 30, 2021Inventors: Anil Paul Thoppil, Cheryl Marie Thompson, Qinghua Zheng, Jeevan Hunsur Eswara, Nicholas Gerald Zehender, Ronak Girishbhai Ghadiya, Sridevi Jantli

Publication number: 20210089387Abstract: Techniques are provided for remote object store error handling. A storage system may store data within one or more tiers of storage, such as a local storage tier (e.g., solid state storage and disks maintained by the storage system), a remote object store (e.g., storage provided by a third party storage provider), and/or other storage tiers. Because the remote object store may not provide the same data consistency and guarantees that the storage system provides for clients such as through the local storage tier, additional validation is provided by the storage system for the remote object store. For example, when data is put into an object of the remote object store, a verification get operation is performed to read and validate information within a header of the object. Other verifications and checks are performed such as using a locally stored metafile to detect corrupt or lost metadata and/or objects.Type: ApplicationFiled: November 22, 2020Publication date: March 25, 2021Inventors: Ananthan Subramanian, Ganga Bhavani Kondapalli, Cheryl Marie Thompson, Kevin Daniel Varghese, Anil Paul Thoppil, Qinghua Zheng

Publication number: 20200159705Abstract: Techniques are provided for orphan object detection, invalid sequence number detection, and asynchronous object cleanup. A storage system may store data within one or more tiers of storage, such as a storage tier (e.g., solid state storage and disks maintained by the storage system), a remote object store (e.g., storage provided by a third party storage provider), and/or other storage tiers. Orphan objects, within the remote object store, that are no longer used by the storage system may be detected and/or deleted. When an aggregate of volumes is deleted, corresponding objects, within the remote object store, may be identified and/or deleted. Invalid sequence numbers (e.g., lost or corrupt sequence numbers locally maintained in a metafile) assigned to objects within the remote object store may be identified, deleted, and/or fixed.Type: ApplicationFiled: January 24, 2020Publication date: May 21, 2020Inventors: Ananthan Subramanian, Sridevi Jantli, Anil Paul Thoppil, Cheryl Marie Thompson, Qinghua Zheng

Patent number: 10489073Abstract: Techniques are provided for multi-tier write allocation. A storage system may store data within a multi-tier storage environment comprising a first storage tier (e.g., storage devices maintained by the storage system), a second storage tier (e.g., a remote object store provided by a third party storage provider), and/or other storage tiers. A determination is made that data (e.g., data of a write request received by the storage system) is to be stored within the second storage tier. The data is stored into a staging area of the first storage tier. A second storage tier location identifier, for referencing the data according to a format utilized by the second storage tier, is assigned to the data and provided to a file system hosting the data. The data is then destaged from the staging area into the second storage tier, such as within an object stored within the remote object store.Type: GrantFiled: April 28, 2017Date of Patent: November 26, 2019Assignee: NetApp Inc.Inventors: Ganga Bhavani Kondapalli, Kevin Daniel Varghese, Ananthan Subramanian, Cheryl Marie Thompson, Anil Paul Thoppil

Patent number: 9965195Abstract: Methods and systems for a networked system are provided. One method includes receiving a request by a processor to transfer a data block stored at a first storage tier to the second storage tier; using an object staging data structure to determine that an object is available for transferring the data block from the first storage tier to the second storage tier. The object staging data structure an indicator providing a status for the object and an object length and an offset value of a transfer log indicating where information regarding the data block is stored. The method further includes updating an address of the storage tier where the information regarding data block is stored at the transfer log; increasing the object length and the offset value at the object staging data structure; and creating the object at the second tier.Type: GrantFiled: November 15, 2017Date of Patent: May 8, 2018Assignee: NETAPP, INC.Inventors: Ananthan Subramanian, Cheryl Marie Thompson, Sunitha Sunil Sankar
