Chapter 1: Introduction 1-2 Chipset Overview Intel’s Mukilteo (E7230) chipset, designed for use with the Pentium 4 Processor in the 90nm Process in the LGA 775 Land Grid Array Package, is comprised of two primary components: the Memory Controller Hub (MCH) and the I/O Control- ler Hub (ICH7R). In addition, Intel's PCI-X (PXH-V) is used for added functionality. The PDSMi provides the performance and feature-set required for the high-end UP Server market. Memory Controller Hub (MCH) The function of the MCH is to manage the data fl ow between four interfaces: the CPU interface, the DDRII System Memory Interface, thePCI Express Interface, and the Direct Media Interface (DMI).
The MCH is optimized for the Pentium 4 proces- sor in the 90nm process in the LGA775 Land Grid Array Package. It supports one or two channels of DDRII SDRAM. The I/O Controller (ICH7R) provides the data buffering and interface arbitration required for the system to operate effi ciently. It also provides the bandwidth needed for the system to maintain its peak performance. The Direct Media Interface (DMI) provides the connection between the MCH and the ICH7R. The ICH7R supports up to six PCI-Express slots, four Serial ATA ports, six USB 2.0 ports and two IDE devices.
In addition, the ICH7R offers the Intel Matrix Storage Technology which provides various RAID options for data protection and rapid data access. It also supports the next generation of client management through the use of PROActive technology in conjunction with Intel's next generation Gigabit Ethernet controller. Intel ICH7R System Features The I/O Controller Hub provides the I/O subsystem with access to the rest of the system. Functions and capabilities include:
