IBM Power System E850C: Technical Overview and Introduction
1.6.1 PCIe Gen3 I/O expansion drawer
PCIe Gen3 I/O expansion drawers (#EMX0) can be attached to the Power E850C to expand
the number of full-high, hot-swap Gen3 slots available to the server. The maximum number of
PCIe Gen3 I/O drawers depends on the number of processor modules physically installed.
The maximum is independent of the number of processor core activations:
Up to two PCIe3 drawers with two processor modules
Up to three PCIe3 drawers with three processor modules
Up to four PCIe3 drawers with four processor modules
Each PCIe Gen3 I/O expansion drawer adds a total of 10 PCIe Gen3 adapter slots to the
server’s capabilities.
Figure 1-4 shows the front of the PCIe Gen3 I/O expansion drawer.
