Each SBA provides the control and interfaces for eight PCI-X slots. The interface is through the rope bus (16 ropes per SBA). For each SBA, the ropes are divided in the following manner: • A single rope is routed to support the core I/O boards through LBAs located on the system backplane. • A single rope is routed to an LBA on the PCI backplane to support a slot for PCI and PCI-X cards (slot 8). • Six ropes are bundled into double ropes to three (3) LBAs. They support slots 1, 2, and 7 for PCI and PCI-X mode 1 cards. • Eight fat ropes are bundled into quad ropes to four (4) LBAs. They support slots 3, 4, 5, and 6 for PCI and PCI-X mode 2 cards. NOTE: PCI-X slots 1-7 are dual rope slots while slot 8 is a single rope slot. A rope is defined as a high-speed, point-to-point data bus. Each of the 16 slots is capable of 33 MHz/66 MHz PCI or 66 MHz/133 MHz PCI-X. Four slots in PCI-X support 266 MHz. All 16 PCI slots are keyed for 3.3 V connectors (accepting both Universal and 3.3 V cards). The PCI-X backplane does not provide any 5 V slots for the I/O cards. Table 1-8 summarizes the PCI-X slot types. The PCI-X backplane is physically one board, yet it behaves like two independent partitions. SBA 0 and its associated LBAs and eight PCI-X slots form one I/O partition. SBA 1 and its associated LBAs and eight PCI-X slots form the other I/O partition. One I/O partition can be reset separately from the other I/O partition but cannot be powered down independently. 26 HP Integrity rx8640 and HP 9000 rp8440 Server Overview
