Zoned Block Devices (ZBDs) devide the LBA space to block regions called zones
that are larger than the LBA size. It can only allow sequential writes, which
reduces write amplification in SSD, leading to higher throughput and increased
capacity. More details about ZBDs can be found at:

By adding zone management operations in BlockDriver, storage controller
emulation can use the new block layer APIs including Report Zone and
four zone management operations (open, close, finish, reset).
Add zoned storage commands of the device: zone_report(zrp), zone_open(zo),
zone_close(zc), zone
