3.4 Interfaces

3.4.1 PCIe

COM-HPC allows for up to 49 PCIe lanes on the Client Module pin-out, and for up to 65 PCIe lanes on
the Server Module. The PCIe lanes are divided into 5 Groups:
Group 0 Low: PCIe lanes 0:7 and also an additional lane for BMC use
Group 0 High: PCIe lanes 8:15
Group 1: PCIe lanes 16:31
Group 2: PCIe lanes 32:47
Group 3: PCIe lanes 48:63 (Server Module only)
