Patent number: 12282434Abstract: The disclosed technology relates to determining physical zone data within a zoned namespace solid state drive (SSD), associated with logical zone data included in a first received input-output operation based on a mapping data structure within a namespace of the zoned namespace SSD. A second input-output operation specific to the determined physical zone data is generated wherein the second input-output operation and the received input-output operation is of a same type. The generated second input-output operation is completed using the determined physical zone data within the zoned namespace SSD.Type: GrantFiled: October 16, 2023Date of Patent: April 22, 2025Assignee: NETAPP, INC.Inventors: Abhijeet Prakash Gole, Rohit Shankar Singh, Douglas P.

Publication number: 20230333740Abstract: The disclosed technology relates to managing input-output operation in a zoned storage system includes identifying a first physical zone and a second physical zone within a zoned namespace solid-state drive associated with a logical zone to perform a received write operation. Data to be written in the received write operation is temporarily staged in a zone random write area associated with the identified second physical zone. Based a storage threshold of the zone random write area, a determination is made regarding when to transfer temporarily staged data to be written area to the identified second physical zone. When the storage threshold of the zone random write area determined to have exceeded, temporarily staged data to be written is transferred to the identified second physical zone.Type: ApplicationFiled: June 28, 2023Publication date: October 19, 2023Applicant: NetApp, Inc.Inventors: Rohit Shankar Singh, Douglas P.
