PCI/PCI-X/PCIe Configurations

This section contains the following topics:

•“PCI/PCI-X IOBP” (page 194)

•“PCI/PCI-X/PCIe IOBP” (page 196)

•“Shared Slots” (page 197)

PCI/PCI-X IOBP

The following describes configuration requirements for slots 1 through 10 on the PCI/PCI-X/ I/O backplane:

•PCI-X slots 1 and 2 are reserved for use by the core I/O cards SAS core I/O cards and the Gigabit Ethernet LAN core I/O card. Slots 1 and 2 are not hot-pluggable. Install only supported PCI-X SAS and LAN core I/O cards in slots 1 and 2. Depending upon the number and type of SAS core I/O cards installed on the system, the Gigabit Ethernet LAN core I/O card may be installed in slot 10.

•Slots 3 and 4 are nonshared slots. The maximum speed for cards in slots 3 and 4 is PCI-X 266 MHz.

•Slots 5 and 6 are nonshared slots. The maximum speed for cards in slots 5 and 6 is PCI-X 133 MHz.

•Slots 7, 8, 9, and 10 are shared slots. These four slots are limited by bus-mode or frequency-related incompatibilities. If you use different modes, such as PCI instead of PCI-X, or different card speeds in a shared bus environment, the slot automatically downgrades to the lesser mode or speed. The maximum capability of each slot is PCI-X 66 MHz. See “Shared Slots” (page 197) for more information.

PCI/PCI-X Card Path Logging Some PCI/PCI-X failures result in I/O path logging. These paths help to indicate the source of the error and can be included in the error message or logged into console or event logs.Table 6-1describes the PCI/PCI-X I/O paths for the server.
