PCI Express implements a switch-based technology to interconnect a
large number of devices. Communication over the serial interconnect is
accomplished using packet-based communication protocol. Quality of
Service (QOS) features provide differentiated transmission performance
for different applications. Hot Plug/Hot Swap support enables “always-on”
systems. Enhanced error handling features, such as end-to-end CRC
(ECRC) and Advanced Error Reporting, make PCI Express suitable for
robust, high-end server applications. Hot Plug, power management, error
handling, and interrupt signaling are accomplished using packet-based
messaging rather than sideband signals. This keeps the device pin count
low and reduces the system cost.
Each of the eight SAS phys on the LSISAS1068E is capable of
SAS/SATA link rates of 3.0 Gbits/s and 1.5 Gbits/s. The user can
configure ports as wide or narrow. Narrow ports have one phy per port.
Wide ports have two, three, or four phys per port. Each port supports the
SSP, SMP, STP, and SATA protocols.
