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 www.hp.com/go/proliant and check the QuickSpecs for a specific server.

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
