Figure 2.3
Each phy on the LSISAS1064 can function as an SSP Initiator, an SSP
target, an SMP initiator, an STP initiator, or a SATA Initiator. A phy can
function in only one role during a connection, but function in different
roles during different connections. The LSISAS1064 uses SSP to
communicate with other SAS devices, and uses SMP to communicate
management information with other SAS devices. STP communicates
with SATA devices in a SAS domain by tunneling through SAS expanders
to the SATA device. The LSISAS1064 can also use SATA to
communicate with other SATA devices.
