Abstract: A host system coupled to a storage system provides hardware support for command abort. The host system includes a host controller, which detects that a host driver has disabled an enable indicator of a submission queue (SQ). In response to the detection, the host controller stops further fetching from the SQ. The host controller sends all entries that have been fetched from the SQ to the storage device, and sets a status indicator of the SQ to indicate stopped fetching of the SQ.

Abstract: Examples and techniques pertaining to a security mechanism for multi-client access to a single storage device through a single controller are described. A controller receives a request from a first client of a plurality of clients to access a storage device which stores data associated with the plurality of clients. The controller determines one or more aspects with respect to the first client. The controller then performs one of a plurality of operations including: (a) granting the first client access the storage device responsive to a positive result of the determining, and (b) rejecting the request responsive to a negative result of the determining. The storage device is divided into a plurality of partitions to store respective data associated with each of the plurality of clients in one or more respective partitions of the plurality of partitions.

Abstract: A host system operates to manage a storage device. The host system initiates an abort of a command when the command has been fetched from a submission queue (SQ) of the host system and the SQ entry has been fetched from the SQ and the host system has not received a corresponding command completion response from the storage device. The host system sends an abort request to the storage device, and issues a cleanup request to direct a host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry to indicate completion of the abort request.

Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.
