Abstract
Zone hints for use with a zoned namespace (ZNS) storage device. Zone hints include one or more of a first hint indicating that a zone is part of a group of a plurality of zones, a second hint indicating that the zone is to be fast-filled, or a third hint indicating that the zone is associated with a background operation. The first hint is structured to instruct the ZNS storage device to allocate to the zone a first storage resources that are physically adjacent to second storage resources reserved for others of the plurality of zones. The second hint is structured to instruct the ZNS storage device to bypass a staging area when writing to the zone. The third hint is structured to instruct the ZNS storage device to deprioritizing at least one operation writing to the zone, or to bypass the staging area when writing to the zone.
