Dell Chassis Management Controller Version 1.3 for PowerEdge FX2/FX2s User's Guide

In split-dual mode, both RAID controllers in a storage sled are connected to two compute sleds.

If a storage sled is located below a full-width PowerEdge FC830 sled, it can be configured in the split-dual mode. But the controllers are connected to a single compute sled and only that compute sled is reported.

If a storage sled is configured in the split dual mode and is in a location where it cannot be connected to two compute sleds, then the second controller is not connected to any compute sled.

You must have the Chassis Configuration Administrator privilege and power off the compute sled before changing the setting.
