Pci-X/Pcie I/O Backplane; Pci-X Slot Types - HP 9000 Integrity rp8440 Installation Manual

IMPORTANT:
specifications. PCI, PCI-X mode 1, and PCI-X mode 2 cards are supported at different clock
speeds. Select the appropriate PCI-X I/O slot for best performance.

1 Each slot will auto select the proper speed for the card installed up to the maximum speed for the slot. Placing high
speed cards into slow speed slots will cause the card to be driven at the slow speed.
2 Slot is driven by a single rope and has a maximum speed of 66 MHz.

PCI-X/PCIe I/O Backplane

The 16–slot (8 PCI and PCI-X; 8 PCI-Express) mixed PCI-X/PCI-Express ("PCIe") I/O backplane
was introduced for the Dual-Core Intel® Itanium® processor 9100 Series release and is heavily
leveraged from the PCI-X backplane design. Only the differences will be descibed here. See
"PCI-X I/O Subsystem" (page 26)
The PCI-X/PCIe I/O backplane comprises two logically independent I/O circuits (partitions) on
one physical board.
• The I/O chip in cell location zero (0) and its associated four PCI-X ASICs, four PCIe ASICs,
and their respective PCI/PCI-X/PCIe slots form PCI-Express I/O partition 0 plus core I/O.
• The I/O chip in cell location one (1) and its associated four PCI-X ASICs, four PCIe ASICs,
and their respective PCI/PCI-X/PCIe slots form PCI-Express I/O partition 1 plus core I/O.
Always refer to the PCI card's manufacturer for the specific PCI card performance
