• 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
®
C230 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
®
C230 series chipset provides up to 20 PCI Express* Root Ports, supporting the PCI Express* Base
Specification, Revision 3.0. Each Root Port x1 lane supports up to 8 Gb/s bandwidth in each direction (16 Gb/s
concurrent). On the Intel
®
Server Board S1200SPL and S1200SPO, PCI Express* Root Ports 1-4 are configured
to support one Gen3 x4 port widths of SAS Module connector; on the Intel
®
Server Board S1200SPL and
S1200SPS, PCI Express* Root Ports 5-8 are configured to support one Gen3 x4 port widths of slot 5. On the
Intel
®
Server Boards S1200SP family product, PCI Express* Root Port 10 is configured to support one Gen1 x1
widths connection with the BMC chip; PCI Express* Root Port 11 and 12 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
®
C230 series chipset provides:
• SATA host controllers that support independent DMA operation on up to eight ports and supports data
transfer rates of up to 6.0 Gb/s (600 MB/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
®
C230 series chipset supports the Serial ATA Specification, Revision 3.0.
