Submission queue commands over fabrics

A multi-host storage system comprising

• a memory;
• a storage controller, communicatively coupled to the memory, to:
• receive, from a first host controller of the multi-host storage system, a first reservation command to acquire access to a storage drive that is shared by a second host controller of the multi-host storage system, the reservation command comprising a first host identifier to identify the first host controller;
• modify the first reservation command by replacing the first host identifier with a first logical unit identifier that is associated with the first host controller and that identifies a first logical unit of storage of the storage drive;
• and
• send the modified first reservation command comprising the first logical unit identifier to a drive controller of the storage drive.

A non-transitory computer-readable medium comprising instructions that, when executed by a multi-host storage system, cause the multi-host storage system to:

• receive, by a storage drive of the multi-host storage system, a modified first submission queue command comprising a first logical unit identifier, wherein a first submission queue command comprises a first host identifier;
• responsive to receiving the modified first submission queue command, identify, by the storage drive, a first logical unit of storage based on the first logical unit identifier of the modified submission queue command;
• and
• grant, by the storage drive, a reservation for access to the storage drive on behalf of the first host controller by associating the reservation for the first logical unit with a second logical unit of storage.
