Abstract
A first I/O controller of a storage server sends a first command to a first solid state drive (SSD) of the storage server via a first submission queue of the first SSD, wherein the first command is a first read command or a first write command. The first I/O controller receives a first acknowledgement from the first SSD that the first command has been completed via a first completion queue of the first SSD. A second I/O controller of the storage server sends a second command to the first SSD of the storage server via a second submission queue of the first SSD, wherein the second command is a second read command or a second write command. The second I/O controller receives a second acknowledgement from the first SSD that the second command has been completed via a second completion queue of the first SSD.
