1.3 Enclosure Connection Path
For a dual-controller type, a controller enclosure (CE) is connected to a drive enclosure (DE) with
multiple paths.
A drive enclosure has two independent DI ports. Path redundancy is maintained by connecting
the drive enclosure to two controllers directly. This configuration allows operation to continue
even if one of the connection paths fails.
