HP is committed to ensuring a smooth transition between I/O standards for customers. HP is beginning to introduce PCI Express technology into next-generation ProLiant servers to coexist with PCI-X 133. This will allow ProLiant server customers to install new higher bandwidth cards (for example, dual 4-Gb Fibre Channel, x4 InfiniBand, and 10-Gb Ethernet) using PCI Express technology beginning in 2004. At the same time, the continued commitment from HP to PCI-X will allow ProLiant server customers to connect to their existing I/O cards. HP will begin phasing PCI Express into Smart Array, ProLiant NIC, and Fibre Channel SAN cards as the technology matures.
PCI Express slots first became available in select ProLiant servers that were introduced in the second half of 2004. ProLiant ML servers have a mix of PCI-X and PCI Express slots, while ProLiant DL servers have optional riser cards to provide different combinations of PCI-X and PCI Express slots.
Customers who require peripheral bandwidth in excess of 1 GB/s will likely find those peripherals implemented with PCI Express technology. It is expected that most device manufacturers will use PCI Express technology for higher bandwidth peripheral devices such as 10-Gb Ethernet and 10-Gb Fibre Channel. For peripherals that require bandwidth less than 1 GB/s, PCI and PCI-X will remain viable technologies and continue to provide backward compatibility. It is anticipated that device vendors will manufacture peripherals with bandwidth requirements in the 1 GB/s range in two versions, providing options for customers to choose either PCI Express or PCI-X technology.
As the customer requirements for higher bandwidth in the I/O subsystem continue to increase, the industry is beginning a transition to PCI Express technology to provide that bandwidth. HP will implement PCI Express in ProLiant servers while maintaining a commitment to PCI-X technology. PCI Express and PCI-X technology will coexist in ProLiant servers, giving customers flexibility in their choice of technology and providing a path for transition to higher bandwidth peripherals.
HP has been a leader in the development and implementation of industry-standard I/O technology and continues to be an active member of the PCI Special Interest Group. HP is committed to delivering industry leading products that meet customer requirements for flexibility, performance, and investment protection. HP demonstrates that commitment by providing a clear transition path to PCI Express technology.
