Intel today presented a new PCI Express virtualizing technology at the IDF.
Called Multi-Root I/O virtualized PCI Express, the technology introduces switching technology into the traditional PCIe pathway.
The technology is being introduced for high-density cluster systems, usually made up of a number of blade servers. Traditionally, each blade would have its own PCIe pathway and its own devices connected to it. If a cluster contained 10 blade servers, each server would have its own gigabit Ethernet device, its own InfiniBand device and its own fiber channel device. Using this topology, management becomes difficult because each technology is individualized into separate blades.
