PCI-X 2.0: The Next Generation of Backward-Compatible PCI
Today there is also a need for a new, higher-performance I/O interface to support emerging, ultrahigh-bandwidth technologies such as 10 Gigabit Ethernet, 10 Gigabit FibreChannel, 4X and 12X InfiniBand, and others. A standard that can meet these performance objectives, while maintaining backward compatibility to previous generations of PCI would undoubtedly provide the ideal solution.
To meet these objectives, the PCI-X 2.0 standard has been developed. PCI-X 2.0 has the performance to feed the most bandwidth-hungry applications while at the same time maintaining complete hardware and software backward compatibility to previous generations of PCI and PCI-X. This paper introduces the PCI-X standard.
