two-wire serial interface chip. The I
performs bus-specific sequences.
The UART provides test and debug access to the LSISAS1064.
The Quad Port module in the LSISAS1064 implements the SSP, SMP,
and STP/SATA protocols, and manages the four SAS/SATA PHYs. The
following subsections describe the Quad Port module. Refer to
Section 2.4, “SAS Functional Description,”
of the LSISAS1064 SAS ports.
The transport modules transmit frames to and from the port layer and
implement the STP, SSP, and SMP protocols. There are four instances of
the transport module, one for each SAS/SATA phy on the LSISAS1064.
The queue manager is responsible for managing various queue
structures that support the SSP, SMP, and STP protocols. The queue
structures are the primary means for the IOP to initiate I/Os to the
hardware, and for the hardware to notify the IOP of I/O status.
The SATA engine provides information to the transport modules to enable
handling of SATA commands. The SATA engine tracks queued
commands per device and provides these tags to the SATA transport
layer blocks.
The port layer connection monitor and switch manages transmission
requests from the transport modules and originates connection requests
to the SAS links. It is also responsible for handling SAS wide port
configurations.
