SAS: In case of an STP interface, the expander displays STP addresses provided to the
SATA drive and the SAS software integrates the STP addresses in the ATA command.

and the data direction identified with data direction arrows. Upstream traffic has an
arrow from right to left:. Downstream traffic has an arrow left to right: .
Layers can be hidden by clicking the corresponding Show/Hide button on the menu bar.
