SysOpt.com heeft een artikel online gegooid over de mogelijke opvolger van PCI: InfiniBand. Eerst wordt uitgelegd waarom de huidige en toekomstige PCI standaarden niet meer voldoen, waarna men verder gaat met het uiteenzetten van de vele features en voordelen van het nieuwe Point-To-Point protocol dat zowel op moederborden als in netwerken gebruikt kan worden. Zo heeft InfiniBand naast intensieve CRC checks onder andere de mogelijkheid om opdrachten een bepaalde prioriteit te geven en kunnen apparaten die kilometers van elkaar verwijderd zijn rechtstreeks communiceren:
Next generation PCI 3.0 and PCI-X specifications appear more promising on paper, but high-end application of these technologies could prove both expensive and inefficient. The 133 MHz PCI-X standard offers more available bandwidth, but limits one device per controller terminating connection. In-order to support the large number of devices required by upper-tier computing systems, an internal PCI-C controller network would require several channel controllers per end connection. Even with this in mind, while future these future PCI technologies offers sustained real-world bandwidth up to 1 Gigabit per second, they still lack the advanced integrity checking and correction features needed for maximum system reliability.
[...] The InfiniBand switched I/O architecture does appear impressive, especially as compared to other current and near future standards. No single connectivity architecture currently available for mass marketing allows for the large variety of features that IBA specifies. Performance estimates appear superb, with transfer rates scaling up to 30 Gigabit per second. Reliability and quality of service is maintained through advanced features like dual CRC checking, Virtual Lanes, priority control, and credit-based flow control. IBA offers connectivity at both the internal and external levels with support for PCB, copper, and fiber optic transmission mediums.
