HP Integrity rx7640 and HP 9000 rp7440 Servers Installation 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 PCI-X/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.
PCI-X/PCIe Slot Boot Paths
PCI-X/PCIe slot boot paths are directly leveraged from the PCI-X backplane. See Table 3 (page 18)
and Table 4 (page 18) for more details.
NOTE: The differences between the PCI X backplane and the PCI-X/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.
