3.8.1 Digital Media Interface (DMI)
Digital Media Interface (DMI) is the chip-to-chip connection between the processor and C600
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.
3.8.2 PCI Express* Interface
The C600 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). PCI Express* Root Ports 1-4 or Ports 5-8 can independently be
configured to support four x1s, two x2s, one x2 and two x1s,or one x4 port widths.
3.8.3 Serial ATA (SATA) Controller
The C600 chipset has two integrated 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 two ports (Port 0 and 1 Only) while all ports support rates up to 3.0 Gb/s (300 MB/s) and up to
1.5 Gb/s (150 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 C600 chipset supports the Serial ATA Specification, Revision
3.0. The C600 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).
3.8.4 AHCI
The C600 chipset provides hardware support for Advanced Host Controller Interface (AHCI), a
standardized programming interface for SATA host controllers. Platforms supporting AHCI may
take advantage of performance features such as no master/slave designation for SATA
devices—each device is treated as a master—and hardware assisted native command queuing.
AHCI also provides usability enhancements such as Hot-Plug. AHCI requires appropriate
software support (for example, an AHCI driver) and for some features, hardware support in the
SATA device or additional platform hardware.
3.8.5 Rapid Storage Technology
The C600 chipset provides support for Intel
®
Rapid Storage Technology, providing both AHCI
(see above for details on AHCI) and integrated RAID functionality. The industry-leading RAID
capability provides high-performance RAID 0, 1, 5, and 10 functionality on up to 6 SATA ports of
the C600 chipset. Matrix RAID support is provided to allow multiple RAID levels to be combined
on a single set of hard drives, such as RAID 0 and RAID 1 on two disks. Other RAID features
include hot-spare support, SMART alerting, and RAID 0 auto replace. Software components
include an Option ROM for pre-boot configuration and boot functionality, a Microsoft Windows*
compatible driver, and a user interface for configuration and management of the RAID capability
of the C600 chipset.
