PCIXkortit

PCIXkortit refers to expansion cards designed for the PCI-X (Peripheral Component Interconnect Extended) bus. This bus was an evolution of the original PCI bus, aiming to provide significantly higher bandwidth for demanding I/O operations. PCI-X was primarily adopted in servers and high-performance workstations during the late 1990s and early 2000s.

These kortit, or cards, encompassed a wide range of functionalities. Common examples include high-speed network interface cards (NICs) for Gigabit Ethernet and beyond, Fibre Channel host bus adapters (HBAs) for storage area networks (SANs), SCSI controllers, and RAID controllers. The increased bandwidth of the PCI-X bus allowed these devices to operate more efficiently, reducing bottlenecks that were common with the older PCI standard.

PCI-X offered speeds of 66 MHz, 100 MHz, 133 MHz, and even 266 MHz and 533 MHz in later revisions, compared to the 33 MHz of standard PCI. This translated to theoretical maximum bandwidths of 1.06 GB/s and 2.13 GB/s for the faster versions. While backward compatible with PCI cards, to achieve the full benefits of PCI-X, both the motherboard and the expansion card needed to support the PCI-X standard. The advent of PCI Express (PCIe) eventually superseded PCI-X due to its serial nature, lower latency, and even greater scalability.
