Fujitsu MBA3300RC, MBC2036RC, MBC2073RC, MBA3147RC, MBA3073RC specifications Connection Rate field

1.5 Address frames

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.

Table 1.23 CONNECTION RATE field

Code	Description
8h	1,5 Gbps
9h	3,0 Gbps
All others	Reserved

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.
