• Active-Active ULP: Both controllers are active using ULP (Unified LUN
Presentation). Data for volumes configured to use write-back cache is
automatically mirrored between the two controllers to provide fault
tolerance.
• Single Controller: There is only a single controller in the enclosure.
• Fail Over: Operation has failed over to one controller because its partner
is not operational. The system has lost redundancy.
• Down: Both controllers are not operational.
