This is a 6 slot rackmount PCI-X expansion system, with expansion via a PCIe*4 interface.

For rackmount industrial computers or servers, this system is ideal where more PCI-X expansion is required from a single PCIe*4 slot. This system supports PCI-X cards, as well as universal and 3.3V PCI cards (not 5.0V PCI cards). The host controller allows existing expansion cards to be used in the latest servers that do not provide PCI-X or 3.3V PCI card slot support.

Due to expansion via PCIe*4, this system can sustain 64bit/66MHz performance.
