Future of PCI-X slots in ProLiant servers

PCI Express (PCIe) is now becoming the predominant I/O bus for new server platforms. HP will continue, however, to provide
legacy support for the different levels of PCI, including PCI-X. HP has introduced PCIe technology into ProLiant servers to coexist
with PCI-X 133, allowing ProLiant server customers to install new higher bandwidth cards (for example, dual 4-Gb Fibre
Channel, x4 InfiniBand, and 10-Gb Ethernet) using PCIe technology. At the same time, the continued commitment from HP to
PCI-X allows ProLiant server customers to connect to their existing I/O cards.
Current ProLiant ML servers have a mix of PCI-X and PCIe slots, while ProLiant DL servers have optional riser boards to provide
different combinations of PCI-X and PCIe slots. Table 2-1 shows the current ProLiant server models and their support for PCI-X.
Next generation ProLiant servers will no longer feature PCI-X slots as standard offerings. However, PCI-X will continue to be
supported on these servers through the use of the appropriate optional riser boards.
For the latest information, go to

Customers requiring peripheral bandwidth in excess of 1 GB/s will most likely find those peripherals implemented with PCIe
technology. It is expected that most device manufacturers will use PCIe technology for higher bandwidth peripheral devices
such as 10-Gb Ethernet. For peripherals that require bandwidth less than 1 GB/s, PCI and PCI-X remain viable technologies
