Functional Architecture
3.4.1.1
All 32-bit, 33MHz PCI I/O is directed through the 6300ESB ICH. The 32-bit, 33MHz PCI
segment created by the 6300ESB ICH is known as the P32-A segment. The P32-A segment
supports the following embedded devices:
3.4.1.2
One 64-bit PCI-X bus segment is directed through the 6300ESB ICH. This PCI-X segment, P64-
A, supports up to three PCI add-in cards on the full-height riser card, and one PCI add-in card
on the low-profile riser card.
3.4.1.3
One x4 PCI Express bus segment is directed through the E7320 MCH. This PCI Express
segment, P64-Express-A, supports one x4 PCI Express add-in card.
3.4.1.4
One x1 PCI Express bus segment is directed through the E7320 MCH. This PCI Express
segment, P64-Express-B, supports the Marvell* 88E8050 Network Interface Controller.
3.4.1.5
The Server Board SE7320VP2 has two riser slots capable of supporting riser cards for both 1U
and 2U system configurations. Because of board placement resulting in different pin
orientations, and expanded technology support associated with the full-height riser, the riser
slots are not the same and require different riser cards.
The low-profile riser slot (J5F1) utilizes a 202-pin connector. It is capable of supporting one low-
profile PCI-X add-in card. The P64-A bus can support bus speeds of up to 66MHz. The bus will
match the card speed of the lowest speed card on the bus. In other words, if any of the add-
cards installed on the P64-A bus supports a maximum of 33MHz, the entire bus will throttle
down to 33MHz to match the supported frequency of that card. When using a three slot riser
card with the low-profile slot, a single PCI-X add-in card must be installed in the bottom PCI slot.
Only one add-in card is supported with the low-profile slot, regardless of whether a one slot or
three slot riser card is used with it. These population rules must be followed to maintain the
signal integrity of the bus.
The full-height riser slot implements an Intel
of supporting riser cards that meet either the PCI-X or PCI Express technology specifications.
As a PCI-X only bus, the P64-A bus can support bus speeds of up to 66MHz with up to three
PCI-X cards installed in the full-height riser slot. The bus speed will match the card speed of the
lowest speed card on the bus. In other words, if any of the add-cards installed on the P64-A bus
supports a maximum of 33MHz, the entire bus will throttle down to 33MHz to match the
