PCIE Server NIC card Application

  • PCI-E NIC Cards provide redundant connectivity to ensure an uninterrupted network connection.

  • PCI-E NIC Cards are ideal for VM environments with multiple operating systems, requiring shared or dedicated NICs.

  • They are specially designed for desktop PC clients, servers, and workstations with few PCI Express slots available.

PCI Express Status


The PCI Express bus started showing up on Mother Boards in 2004 as an addition (using a new connector) to the PCI interface, and will coexist and out-pace parallel PCI at the rate PCI took over from the ISA bus. One common PCIe implementation seems to have two 1x PCI Express slots [for expansion boards] and one 16x PCIe slot [used to replace the AGP slot], then some number of standard parallel (classic) PCI slots [3 to 4 connectors]. 


Because of the large number of PCI boards fielded it may be some time before the PCI expansion slots disappear from mother-boards, but may disappear faster because the PCIe 1x connector is so much smaller than the PCI connector. The 1x PCIe slots will support a bandwidth of 5Gbps, and the 16x PCIe slot will support 80Gbps. Throughput is discussed below.

Gigabit PCI Card

Gigabit PCI Card


We saw some Mother Board manufacturers using the term PCI-E to represent PCI Express card slots, this is an incorrect usage. PCI Express is not compatible with the standard PCI bus. The PCI Express connectors, signal voltage levels, and signal format are different then with PCI. The physical size of PCI Express cards has the same dimensions as standard PCI cards. The main physical difference between the two bus formats lay with the connectors. PCI Express comes as either standard or low-profile form factors.


Additional Notes: Some software written for the PCI bus may be compatible with the PCIe bus. PCI Express was originally developed at Intel by the Arapahoe working group, later called 3GIO, the "third-generation input/output". Now that the spec has been transferred to the PCI Special Interest Group (PCI-SIG) it was renamed PCI Express.
