8 Chipset

8.1 Overview

The PowerEdge R210 II planar incorporates the Intel C200 Series PCH chipset. The features listed below are part of the chipset.

8.2 Direct Media Interface

Direct Media Interface (DMI) is the chip-to-chip connection between the processor and C200 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.

8.3 PCI Express Interface

The C200 series provides up to 8 PCI Express root ports. Each root port supports 5GT/s bandwidth. PCI Express Root Ports 1-4 can be statically configured as four x1 ports or ganged together to form one x4 port. Ports 5 and 6 can only be used as two x1 ports.

8.4 SATA Interface

The chipset has two integrated SATA host controllers that support independent DMA operation on up to six port: 6 x 3Gb/s SATA. 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.

8.5 AHCI

The chipset provides hardware support for Advanced Host Controller Interface (AHCI), a new 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.

8.6 PCI Interface

The C200 Series chipset PCI interface provides a 33 MHz, Revision 2.3 implementation. The chipset integrates a PCI arbiter that supports up to four external PCI bus masters in addition to the internal requests. This allows for combinations of up to 8 PCI down devices and PCI slots.

8.7 Low Pin Count (LPC) Interface

The LPC bridge function of the PCH resides in PCI Device 31: Function 0. In addition to the LPC bridge function, D31:F0 contains other functional units including DMA, Interrupt controllers, Timers, Power Management, System Management, GPIO, and RTC.

8.8 Serial Peripheral Interface (SPI)

The chipset implements an SPI Interface as an alternative interface for the BIOS flash device. An SPI flash device can be used as a replacement for the FWH, and is required to support Gigabit Ethernet,
