Functional Architecture
3.2.1.3
The Intel E7320 MCH is one of the first Intel chipsets to support the new PCI Express* high-
speed serial I/O interface for superior I/O bandwidth. The scalable PCI Express interface
complies with the PCI Express Interface Specification, Rev 1.0a. On the Server Board
SE7320VP2, the MCH provides two x4 PCI Express interfaces, each with a maximum
theoretical bandwidth of 4 GB/s.
The E7320 MCH is a root class component as defined in the PCI Express Interface
Specification, Rev 1.0a. The PCI Express interfaces of the MCH support connection to a variety
of bridges and devices compliant with the same revision of the specification. See the Server
Board SE7320VP2 Tested Hardware and OS List for the tested add-in cards.
3.2.1.4
The MCH interfaces with the Intel
which supports a peak bandwidth of 266MB/s using a x4 base clock of 66 MHz.
3.2.1.5
Using Intel
both PCI-X signals from the I/O Controller Hub (6300ESB ICH) and PCI Express signals from
the MCH routed to it. Depending on the riser card, the slot supports both PCI-X and/or PCI
Express add-in cards. The placement of this slot allows risers supporting full-height, full-length
add-in cards to be used.
3.2.1.6
The low-profile riser slot is a standard 202-pin slot connector supporting PCI-X signals from the
I/O Controller Hub (6300ESB ICH). Because of available board clearances, riser cards can only
support low-profile add-in cards with this slot.
3.2.2
The 6300ESB ICH is a multi-function device providing an upstream hub interface for access to
several embedded I/O functions and features including:
