2.2 Logical system design

This section contains logical diagrams of the Power E850C server in different configurations.
It also covers some factors to consider when configuring a new or upgraded Power E850C
server.
The Power E850C can be configured with two, three, or four processor modules installed. The
number of memory CDIMM slots and the number of PCIe adapter slots that can be used
varies based on the number of processor modules installed. Table 2-2 shows the available
options.

The number of available PCIe adapters supported can be increased by adding PCIe Gen3 I/O
expansion drawers to the server. The Power E850C can support up to one PCIe I/O
expansion drawer per processor module.
The following factors can influence the placement of PCIe cards in the Power E850C server:
All PCIe slots in the system node are SR-IOV capable.
