PCI-X is a compatible extension of the existing PCI Bus. It provides the increased bandwidth and bus performance needed to address I/O demands from enterprise applications, such as Fibre Channel, Ultra3 SCSI, SAN interconnects, and Gigabit Ethernet.
The PCI-X 64-bit architecture runs at speeds of up to 133 MHz, providing burst transfer rates above 1 GB per second. The technology also increases the fault isolation of the PCI bus by enabling the operating system to work more effectively with adapters to better manage error conditions.
PCI-X is designed so that enterprises can use multiple PCI-X buses at varying speeds as well as add buses for ultra-high performance and hot-pluggability.
The ProLiant DL760 is one of Compaq's two new 8-way ProLiant server models featuring Intel Pentium III Xeon processors. The DL760 is currently being incorporated into the ProLiant ML and DL server lines.
The next-generation ProLiant 8000 will be introduced as the ProLiant ML750, and the successor to the ProLiant 8500 will be relabeled as the ProLiant DL760, with the 700 MHz models available immediately and the 900 MHz models shipping based on processor availability from Intel.
"Compaq earned greater than 60 percent market share leadership with ProLiant servers in the 8-way arena by driving innovation that gives enterprise customers a distinct advantage," said James Mouton, vice president of enterprise servers, Industry Standard Server Group, Compaq.
The PCI-X technology was developed by Compaq for its Profusion chipset architecture. However, in addition to including the technology in various products of its own, Compaq plans to license it to other technology manufacturers.
