All PCIe x16 slots in the system node have dedicated bandwidth (16 lanes of PCIe Gen 3
bandwidth).
One of the PCIe x8 slots (C11) has dedicated bandwidth (eight lanes of PCIe Gen3
bandwidth). The other two PCIe x8 slots (C6 and C7) share bandwidth (by using the PEX
unit, and also shared with the USB 3.0 controller).
All PCIe x16 slots in the system node are CAPI capable.
At least one PCIe Ethernet adapter is required on the server by IBM to ensure proper
manufacture and test of the server. One of the x8 PCIe slots is used for this required
adapter, identified as the C11 slot.
Figure 2-4 shows the logical design of the Power E850C server with two processor modules
installed.
