Intel Direct Media Interface (DMI)

The DMI (previously called the Enterprise Southbridge Interface) connects the Tylersburg IOH with the Intel I/O Controller Hub (ICH). The DMI is equivalent to a x4 PCIe Gen1 link with a transfer rate of 1 Gb/s in each direction.

PCI Express Generation 2

PCI Express is a serial point-to-point interconnect for I/O devices. PCIe Gen2 doubles the signaling bit rate of each lane from 2.5 Gb/s to 5 Gb/s. Each of the PCIe Gen2 ports are backwards-compatible with Gen1 transfer rates.

In the Tylersburg-36D IOH, there are two x2 PCIe Gen2 ports (1Gb/s) and eight x4 PCIe Gen2 ports (2 Gb/s). The x2 ports can be combined as a x4 link; however, this x4 link cannot be combined with any of the other x4 ports. Two neighboring x4 ports can be combined as a x8 link, and both resulting x8 links can combine to form a x16 link.

Intel I/O Controller Hub 9 (ICH9)

ICH9 is a highly integrated I/O controller, supporting the following functions:

•Six x1 PCIe Gen1 ports, with the capability of combining ports 1-4 as a x4 link

•These ports are unused on the PowerEdge R610

•PCI Bus 32-bit Interface Rev 2.3 running at 33MHz

•Up to six Serial ATA (SATA) ports with transfer rates up to 300 MB/s

•The PowerEdge R610 features two SATA port for optional internal optical drive or tape backup

•Six UHCI and two EHCI (High-Speed 2.0) USB host controllers, with up to twelve USB ports

•The PowerEdge R610 has eight external USB ports and two internal ports dedicated for

UIPS. Refer to the Whoville Hardware/BIOS Specification for the USB assignments for each platform

•Power management interface (ACPI 3.0b compliant)

•Platform Environmental Control Interface (PECI)

•Intel Dynamic Power Mode Manager

•I/O interrupt controller

•SMBus 2.0 controller

•Low Pin Count (LPC) interface to Super I/O, Trusted Platform Module (TPM), and SuperVU

•Serial Peripheral Interface (SPI) support for up to two devices

•The PowerEdge R610’s BIOS is connected to the ICH using SPI
