• P64H2 PCI Controller Hub
• ICH3 I/O Controller Hub
®
The Intel Server Board SE7500WV2 is designed around the Intel E7500 chipset, a set of controller chips that support
the core functions of the server board. This chipset utilizes a controller hub architecture and includes the following
components:
•
E7500 Memory Controller Hub (MCH):
−
Monitors the processor bus for access requests and directs those requests to memory or to one of the PCI buses
as appropriate
−
Contains an integrated memory controller that controls data transfers to and from memory and handles error
detection and correction
−
Provides hub links for both the P64H2 and the ICH3
−
Accepts inbound requests from the P64H2 and the ICH3 for direction to either the processor subsystem or
memory subsystem
•
P64H2 PCI Controller Hub:
−
Connects to the E7500 MCH through a Hub Interface 2.0 bus that provides over 1 GB/s of bandwidth
−
Provides interfaces to two 64-bit, PCI-X buses
−
Acts as both a target and a master on the PCI-X buses
•
ICH3 I/O Controller Hub:
−
Connects to the E7500 MCH through a Hub Interface 1.5 bus that provides 266 MB/s of bandwidth
−
Provides the interface for one 32-bit, 33-MHz PCI bus
−
Acts as both a target and a master on the PCI bus
−
Integrated PCI bus master ATA-100 IDE controller
−
Three integrated universal serial bus (USB) controllers
−
Integrated 16-entry advanced programmable interrupt controller (APIC) to distribute PCI interrupts
−
Integrated advanced configuration and power interface (ACPI)
−
Provides a low pin count (LPC) interface connecting to the SuperI/O* controller for floppy, PS/2, COM port
and hardware monitor functions
