    Abstract: Methods, non-transitory machine-readable media, and computing devices that manage resources between multiple hosts coupled to dual-port solid-state disks (SSDs) are disclosed. With this technology, in-core conventional namespace (CNS) and zoned namespace (ZNS) mapping tables are synchronized by a host flash translation layer with on-disk CNS and ZNS mapping tables, respectively. An entry in one of the in-core CNS or ZNS mapping tables is identified based on whether a received storage operation is directed to a CNS or a ZNS of the dual-port SSD. The entry is further identified based on a logical address extracted from the storage operation. The storage operation is serviced using a translation in the identified entry for the logical address, when the storage operation is directed to the CNS, or a zone identifier in the identified entry for a zone of the ZNS, when the storage operation is directed to the ZNS.
