This topic provides rules and examples of a configuration that uses a three-way split backplane.

The following rules apply to this configuration:

Example: Three-way split backplane

This example shows a three-way split backplane configuration. Each embedded SAS adapter controls two disk drives, and the SAS adapter that is connected to the internal cable controls two disk drives.
