S2600GZ and S2600GL

Intel® Server Board S2600GZ/GL TPS Product Architecture Overview
Each PCIe port from the given processor IIO module can be bifurcated down to smaller segments as needed.
The number of PCIe port segments required is dependent on the number and type of PCIe devices that need
to be supported for the given system configuration. The root port is identified by the port number followed by
the letter “A”. As each port is bifurcated, the smaller segments are identified by the port number followed by
sequential letters starting with “A”. The following diagrams illustrate possible PCIe port bifurcation options and
port identification.
