Which statement describes Celerra unified system Fibre Channel connectivity to the back end?
A.
Direct connection support for CLARiiON only
B.
Switched fabric connection to Symmetrix only
C.
Multiple array support for Symmetrix only
D.
Multiple array support for CLARiiON only
Gateway systems do not come with any backend storage but rather connect to an existing backend storage array. The Data Mover Fibre Channel connectivity to the backend storage is either via a direct connection or a SAN connection. The backend storage does not connect to the Control Station management network, it connects to the site public network and has public network addressing. The backend storage can also be shared with other SAN connected hosts. The backend storage can be either a Symmetrix or a CLARiiON array. And a Gateway system can have multiple backend storage arrays.
A Unified system includes a backend CLARiiON storage array. The backend storage has been ―integrated‖ with the other Celerra components at the manufacturing facility—having its NAS code installed onto the backend storage. The Unified system Data Movers connect directly to the backend storage. The backend storage is connected to the management network and is assigned site public network addressing. On a Unified system the backend storage must be a CLARiiON array and is limited to having just a single backend storage array.
