Functional Architecture IntelP®P Server Board S3420GP TPS
When operating with two PCI Express* controllers, each controller can operate at either 2.5
GT/s or 5.0 GT/s. The PCI Express* architecture is specified in three layers: Transaction Layer,
Data Link Layer, and Physical Layer. The partitioning in the component is not necessarily along
