Functional Architecture Intel® Server Board S1200V3RP  System Management Bus (SMBus* 2.0)  Integrated NVSRAM controller  Virtualization Technology for Direct I/O (Intel® VT-d)  JTAG Boundary-Scan  KVM/Serial Over LAN (SOL) Function 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). Table 7.
