Oracle^® Server X7-8 Installation Guide

Back Panel Components

The components on the back panel are divided between System A and System B. System A is associated with SMOD0. System B is associated with SMOD1.

• In single 4-socket systems, System A is active and System B is inactive.

• In dual 4-socket systems, System A and System B are active and act as independent servers.

• In single 8-sockets, System A and System B are active and merged into a single server, although some redundant features in SMOD1 are nonfunctional.

The following figure shows the Oracle Server X7-8 back panel.
