HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

The ropes in each I/O partition are distributed as follows:

• One PCI-X ASIC is connected to each I/O chip with a single rope capable of peak data rates

of 533Mb/s (PCIX-66).

• Three PCI-X ASICs are connected to each I/O chip with dual ropes capable of peak data

rates of 1.06Gb/s (PCIX-133).

• Four PCIe ASICs are connected to each I/O chip with dual fat ropes capable of peak data

rates of 2.12Gb/s (PCIe x8).

In addition, each I/O chip provides an external single rope connection for the core I/O.

Each PCI-Express slot on the PCIe I/O board is controlled by its own ASIC and is also independently

supported by its own half of the dual hot swap controller. All PCIe slots are designed to be compliant

with PCIe Rev.1.0. The PCI-Express I/O backplane will provide slot support for VAUX3.3, SMB*,

and JTAG.

PCIe Slot Boot Paths

PCIe slot boot paths are directly leveraged from the PCI-X backplane. See Table 5 (page 20) and

Table 6 (page 21) for more details.

NOTE: The differences between the PCI X backplane and the PCIe backplane are as follows:

• Twelve ropes are bundled in two rope pairs to 6 LBAs to support 6 slots for PCI and PCI-X

cards instead of 14. These ropes are capable of 133MHz.

• Sixteen ropes are bundled into dual fat ropes to 8 LBAs to support 8 additional slots for PCIe

cards. These ropes are capable of 266MHz.
