1.5 Address frames

An SSP INITIATOR PORT bit set to one specifies that an SSP INIT port is present. An SSP INITIATOR PORT bit set to zero specifies that an SSP INIT port is not present. Expander devices shall set the SSP INITIATOR PORT bit to zero.

An SSP TARGET PORT bit set to one specifies that an SSP TARG port is present. An SSP TARGET PORT bit set to zero specifies that an SSP TARG port is not present. Expander devices shall set the SSP TARGET PORT bit to zero.

For SAS ports, the SAS ADDRESS field specifies the port identifier of the SAS port transmitting the IDENTIFY address frame. For expander ports, the SAS ADDRESS field specifies the device name of the expander device transmitting the IDENTIFY address frame.

The PHY IDENTIFIER field specifies the phy identifier of the phy transmitting the IDENTIFY address frame.

A wide port shall set the DEVICE TYPE field, SSP INITIATOR PORT bit, STP INITIATOR PORT bit, SMP INITIATOR PORT bit, SSP TARGET PORT bit, STP TARGET PORT bit, and SMP TARGET PORT bit to the same set of values on each phy in the wide port. Recipient ports need not check the consistency of these fields across phys.

The contents of the IDENTIFY address frame sent by a drive are as follows:

a)ADDRESS FRAME TYPE: 0h

b)

DEVICE TYPE:

001b

c) SSP INITIATOR PORT bit:

0b

d)

STP INITIATOR PORT bit:

0b

e)SMP INITIATOR PORT bit: 0b

f)

SSP TARGET PORT bit:

1b

g)

STP TARGET PORT bit:

0b

h)

SMP TARGET PORT bit:

0h

i)

SAS ADDRESS:

Refer to the Section 1.2.1, "SAS address."

j)

PHY IDENTIFIER:

port A (0h)/port B (1h)

k)

Reserved:

0h
