3.4.1 Digital Media Interface (DMI)
Digital Media Interface (DMI) is the chip-to-chip connection between the processor and the
Intel
®
C220 series chipset. This high-speed interface integrates advanced priority-based
servicing allowing for concurrent traffic and true isochronous transfer capabilities. Base
functionality is completely software-transparent, permitting current and legacy software to
operate normally.
3.4.2 PCI Express* Interface
The Intel
®
C220 series chipset provides up to 8 PCI Express* Root Ports, supporting the PCI
Express* Base Specification, Revision 2.0. Each Root Port x1 lane supports up to 5 Gb/s
bandwidth in each direction (10 Gb/s concurrent). On the Intel
®
Server Board S1200V3RPL and
S1200V3RPS, PCI Express* Root Ports 1-4 is configured to support one Gen2 x4 port widths of
slot 4; PCI Express* Root Port 8 is configured to support one Gen2 x1 port widths of slot 7. On
the Intel
®
Server Boards S1200V3RP family product, PCI Express* Root Port 5 is configured to
support one Gen1 x1 widths connection with the BMC chip; PCI Express* Root Port 5 and 6 are
configured to support two Gen1 x1 widths connection with the two Intel
®
I210 Gigabit Ethernet
Network controller.
3.4.3 Serial ATA (SATA) Controller
The Intel
®
C220 series chipset provides SATA host controllers that support independent DMA
operation on up to six ports and supports data transfer rates of up to 6.0 Gb/s (600 MB/s) on up
to six ports while all ports support rates up to 3.0 Gb/s. The SATA controller contains two modes
of operation – a legacy mode using I/O space, and an AHCI mode using memory space.
Software that uses legacy mode will not have AHCI capabilities. The Intel
®
C220 series chipset
supports the Serial ATA Specification, Revision 3.0. The Intel
®
C220 series also supports
several optional sections of the Serial ATA II: Extensions to Serial ATA 1.0 Specification,
Revision 1.0 (AHCI support is required for some elements).
