Abstract: Data recovery is enabled using techniques described herein. A system can include data storage devices configured in a plurality of logical configurations, wherein the logical configurations are respectively associated with respective groups of the data storage devices, and wherein the respective groups of the data storage devices are structured such that at least a first one of the respective groups of the data storage devices comprises a different number of data storage devices than a second one of the respective groups of the data storage devices; and respective parity storage devices communicatively coupled to the data storage devices, wherein respective ones of the groups of the data storage devices are associated with respective ones of the parity storage devices.

Abstract: Offloaded delete operations is described. A target system receives an offloaded data transfer token from a host, with the offloaded data transfer token specifying source data information. The target system identifies the source data and the source storage based on the source data information. The target system determines whether the offloaded data transfer token specifies an offloaded delete operation. The target system deletes the source data from the source storage if the offloaded data transfer token specifies the offloaded delete operation.
