Dell™ PowerEdge™ R610 Technical Guidebook31Intel Direct Media Interface (DMI)The DMI (previously called the Enterprise Southbridge Interface) connects the Tylersburg IOH with theIntel I/O Controller Hub (ICH). The DMI is equivalent to a x4 PCIe Gen1 link with a transfer rate of 1 Gb/sin each direction.PCI Express Generation 2PCI Express is a serial point-to-point interconnect for I/O devices. PCIe Gen2 doubles the signaling bitrate of each lane from 2.5 Gb/s to 5 Gb/s. Each of the PCIe Gen2 ports are backwards-compatible withGen1 transfer rates.In the Tylersburg-36D IOH, there are two x2 PCIe Gen2 ports (1Gb/s) and eight x4 PCIe Gen2 ports (2Gb/s). The x2 ports can be combined as a x4 link; however, this x4 link cannot be combined with any ofthe other x4 ports. Two neighboring x4 ports can be combined as a x8 link, and both resulting x8 linkscan 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 ortape 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 forUIPS. Refer to the Whoville Hardware/BIOS Specification for the USB assignments foreach 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 SPIsectiOn 9. biOsa. Overview / DescriptionThe PowerEdge R610 BIOS is based on the Dell BIOS core, and supports the following features:• Nehalem-EP 2S Support• Simultaneous Multi-Threading (SMT) support• CPU Turbo Mode support• PCI 2.3 compliant• Plug n’ Play 1.0a compliant• MP (Multiprocessor) 1.4 compliant• Boot from hard drive, optical drive, iSCSI drive, USB key, and SD card• ACPI support• Direct Media Interface (DMI) support• PXE and WOL support for on-board NICs• Memory mirroring and spare bank support
