The ADDRESS FRAME TYPE field shall be set to 1h.
The FEATURES field shall be set to zero.
The CONNECTION RATE field specifies the connection rate being requested
between the source and destination, and is defined in Table 1.23.
When requesting a connection to a SAS TARG port, a SAS INIT port shall set the
CONNECTION RATE field to a value supported by at least one potential
pathway.
When requesting an SSP connection to an SSP INIT port, an SSP TARG port
shall set the CONNECTION RATE field to the connection rate in effect when the
command was received unless it has received an OPEN_REJECT
(CONNECTION RATE NOT SUPPORTED).
The INITIATOR CONNECTION TAG field is used when the SAS TARG port
issues a connection request. This field is used as a substitute for the SAS address
of the SAS TARG port when the SAS INIT port searches for processing in
progress. If the initiator port does not require field support from the SAS TARG
port, the INITIATOR CONNECTION TAG field is set to FFFFh. If the initiator
port requires field support, the INITIATOR CONNECTION TAG field should be
set to the value that is peculiar to the SAS TARG port. When the SAS TARG
port issues a connection request to the SAS INIT port, the SAS TARG port must
set the INITIATOR CONNECTION TAG field to any of the following: the last
received value, the uncompleted command that has been received from the SAS
INIT port, or the value that has been set at the time of the connection request of
the task management. For all connection requests, the SAS INIT port must use
the same INITIATOR CONNECTION TAG value for the same SAS TARG port.
The SAS INIT port can change the INITIATOR CONNECTION TAG value only
when there is no command processing in progress or task management in the SAS
TARG port. The SAS TARG port does not check for consistency among
INITIATOR CONNECTION TAG fields of different connection requests from
the same SAS INIT port.
The DESTINATION SAS ADDRESS field indicates the port identifier of the
SAS port to which a connection request is being made.
The SOURCE SAS ADDRESS field indicates the port identifier of the SAS port
that has been issued an OPEN address frame.
