DellPowerEdge R410 Technical Guide 317.2.3 PCI Express InterfacesPCI Express Interfaces include:• Intel 5500 chipset IOH provides multiple PCI Express* Gen 2 interfaces• Point-to-point, serial bi-directional interconnect• One x4 ESI link to ICH10• Up to six x4 PCI Express Gen 2 ports• x4 link pairs can be combined to form x8 links and or x16 links• Each signal is 8b/10b encoded with an embedded clock• Signaling bit rate of 5 Gbit/sec/lane/direction; for an x4 link, bandwidth is 2 GB/sec in eachdirection• Hot Insertion and Removal supported with the addition of Hot-Plug control circuitry7.2.4 SMBus Interfaces• Connected globally to CPUs, IOHs, and ICH through a common shared bus hierarchy.• Low pin count, low speed management interface• Provides access to configuration status registers (CSR’s)• Mastered by the baseboard management controller (BMC)7.2.5 ESI interfaceThe ESI interface connects the Intel 5500 chipset MCH to the ICH10R. The ESI interface runs at 2 GB/swith a 100 MHz reference clock.7.3 Intel ICH10R South BridgeThe PowerEdge R510 planar incorporates the Intel ICH10R chip. The ICH10R is a highly integrated I/Ocontroller.7.3.1 DMI interfaceThe DMI interface connects the ICH10R to the IOH. The DMI interface runs at 2 GB/s with a 100 MHzreference clock.7.3.2 SATA interfaceThe ICH10R contains 6 integrated Serial ATA host controllers capable of independent DMA operationon 6 ports.The ICH10R SATA interface supports data transfers up to 300 MB/s. The ICH10R has an integratedAHCI controller.7.3.3 USB interfaceThe ICH10R is USB 2.0 compliant. It has six UHCI host controllers to support twelve ports and twoEHCI host controller to support twelve ports. An over-current condition can be detected on all twelveports.
