Abstract: Methods and systems for a storage environment are provided. One method includes splitting storage of a plurality of zoned solid-state drives (ZNS SSDs) into a plurality of physical zones (PZones) across a plurality of independent media units of each ZNS SSD, the PZones visible to a first tier RAID (redundant array of independent disks) layer; generating a plurality of RAID zones (RZones), each RZone having a plurality of PZones; presenting one or more RZones to a second tier RAID layer by the first tier RAID layer for processing read and write requests using the plurality of ZNS SSDs; and utilizing, by the first tier RAID layer, a parity PZone at each ZNS SSD for storing parity information corresponding to data written in one or more PZone corresponding to a RZone presented to the second tier RAID layer and storing the parity information in a single parity ZNS SSD.

Abstract: 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.
