Abstract
According to one embodiment, an apparatus is capable of exchanging a frame with an external apparatus in a packet mode of serial attached small computer system interface (SAS). The apparatus includes a controller configured to transmit a frame to the external apparatus, and to transmit a PACKET_SYNC extended binary primitive to the external apparatus when the frame is not correctly received by the external apparatus.
Claims20
An apparatus capable of exchanging a frame with an external apparatus in a packet mode of serial attached small computer system interface (SAS), the apparatus comprising:
- a controller configured to:
- transmit a frame to the external apparatus, the frame being scrambled, and
- transmit a PACKET_SYNC extended binary primitive to the external apparatus when the frame is not correctly received by the external apparatus, the PACKET_SYNC extended binary primitive causing a de-scrambler of the external apparatus to be initialized.
An apparatus capable of exchanging a frame with an external apparatus in a packet mode of serial attached small computer system interface (SAS), the apparatus comprising:
- a controller configured to transmit a PACKET_SYNC extended binary primitive to the external apparatus in accordance with transmitting a SAS protocol layer (SPL) packet including a primitive, a binary primitive, or an extended binary primitive to the external apparatus, the PACKET_SYNC extended binary primitive causing a de-scrambler of the external apparatus to be initialized.
A method of controlling an apparatus capable of exchanging a frame with an external apparatus in a packet mode of serial attached small computer system interface (SAS), the method comprising:
- transmitting a frame to the external apparatus, the frame being scrambled;
- and
- transmitting a PACKET_SYNC extended binary primitive to the external apparatus when the frame is not correctly received by the external apparatus, the PACKET_SYNC extended binary primitive causing a de-scrambler of the external apparatus to be initialized.
