Hardware Interfaces
For DD580g front and back panel hardware interfaces, see “DD580, DD565, DD530, and DD510
Systems” on page 45. For DD560g and DD460g front and back panel hardware interfaces, see
“DD560, DD460, DD430, and DD410 Systems” on page 61.

Supported Connectivity
Data Domain Gateway systems store data in and restore data from externally attached disk arrays
through Fibre Channel connections. Currently, the Data Domain Gateway systems support the
following types of connectivity:
•
Fibre Channel direct-attached connectivity to a storage array using a 1, 2, or 4 Gb/sec Fibre
Channel interface. The FC-AL loop mode is required.
•
Fibre Channel SAN-attached connectivity to a storage array using a 1, 2, or 4 Gb/sec Fibre
Channel interface.
See the
Gateway Compatibility Matrix
on the Data Domain Support web site for the latest updates
of certified storage arrays, storage firmware, and SAN topology.
Controllers and Ports
A single storage controller port is needed for direct connect to the gateway. Optional redundant
connectivity is supported. If redundant connectivity is not used, port and controller failover on the
storage array must be disabled.
The storage array can have single or multiple controllers and each controller can have multiple
ports.
The storage array port used for gateway connectivity cannot be shared with other SAN-connected
hosts that access the array.
