Intel® E7500 Chipset Platform Overview
The Intel® E7500 chipset represents the next step in Intel® server chipset technology. The first in a family of volume chipsets, the Intel E7500 chipset supports dual processor server platforms optimized for the Intel® Xeon" processor with 512 KB L2 cache and Intel® NetBurst" microarchitecture. The Intel E7500 chipset design delivers maximized system bus, memory, and I/O bandwidth to enhance performance, scalability, and end-user productivity while providing a smooth transition to the next-generation server technologies.
Benefits of Advanced Technology and I/O Flexibility
The Intel E7500 chipset utilizes a modular design and offers platform implementation flexibility to meet the expanding needs of dual processor (DP) servers through three core components:
- The Intel® E7500 Chipset Memory Controller Hub (MCH) is the central hub for all data passing through core system elements such as the dual Intel Xeon processors with 512 KB L2 cache via the system bus interface, the memory via memory interface, and both the 64-bit PCI/PCI-X and I/O controller hubs via Intel® Hub Interfaces. The Intel E7500 chipset delivers compelling performance at 3.2 GB/s of bandwidth across the 400 MHz system bus and up to 3.2 GB/s of bandwidth across two high-performance Double Data Rate SDRAM memory channels. To balance the performance offered by the processor and memory interfaces, the MCH allows several high-bandwidth I/O configuration options for a total of 3.2 GB/s of I/O bandwidth. Together, these features deliver balanced, high-throughput system performance for dual processor server platforms.
- The Intel® 82870P2 64-bit PCI/PCI-X Controller Hub 2 (P64H2) connects to the MCH through a point-to-point Hub Interface 2.0 connection. Up to three P64H2 devices can be attached to the MCH, each providing an I/O bandwidth greater than 1 GB/s for a total of 3.2 GB/s of I/O bandwidth. Each P64H2 contains two independent 64-bit PCI-X interfaces and two PCI hot plug controllers, one per PCI-X interface. Each 64-bit PCI-X segment supports multiple PCI-X slots for high-bandwidth connectivity of next-generation components such as Intel® Gigabit Ethernet adapters and Intel® I/O processors.
- The Intel® 82801CA I/O Controller Hub 3-S (ICH3-S) connects to the MCH through a point-to-point Hub Interface 1.5 connection. The ICH3-S provides legacy I/O interfaces through integrated features including a two-channel Ultra ATA/100 bus master IDE controller and three USB controllers for up to six USB ports. The ICH3-S also offers an integrated System Manageability Bus 2.0 (SMBus 2.0) controller, an integrated LAN controller, as well as AC97 2.2-compliant and PCI 2.2-compliant interfaces.
Features that Maximize Performance and Balance the Platform
- Dual Intel Xeon processors with 512 KB L2 cache and a 400 MHz system bus provide up to 3.2 GB/s of available bandwidth.
- Dual DDR-200 memory channels operate in lock-step to provide up to 3.2 GB/s of memory bandwidth.
- Three Hub Interface 2.0 connections provide multiple high-bandwidth I/O configuration options, yielding up to 3.2 GB/s of I/O bandwidth.
