External Connectivity
For configuration and administrative tasks, you need a serial console, or an Ethernet connection, or
a keyboard and monitor.
All systems have two copper Ethernet connections on the motherboard. These can be used for
system management and for data transfer to and from servers. Optional additional interfaces are
available for all models except the DD120. For an Ethernet connection, you can configure different
network interfaces on a Data Domain system to different subnets. However, if the Data Domain
software version is prior to DD OS 4.5, you must not link multiple interfaces to the same LAN or
VLAN in the network.
Proper connectivity requires that you must use the proper cable and connector types.
•
If the Data Domain system uses fiber gigabit Ethernet interfaces, the cables and connecting
ports on the other end must be SX compatible.
•
If the Data Domain system uses copper gigabit Ethernet interfaces, the cables and connecting
ports on the other end must be RJ45 compatible.
•
If the Data Domain system uses copper 10 gigabit Ethernet interfaces, the cables and
connecting ports on the other end must be copper 10GbE CX4 compatible.
•
If the Data Domain system uses optical 10 gigabit Ethernet interfaces, the cables and
connecting ports on the other end must be optical 10GbE LC compatible.
All Data Domain systems except the DD120 support Fibre Channel VTL connectivity for data
transfer to and from backup servers.
•
If the Data Domain system uses optical 2 gigabit Fibre Channel interfaces, the cables and
connecting ports on the other end must be optical 2Gb FC LC compatible.
•
If the Data Domain system uses optical 4 gigabit Fibre Channel interfaces, the cables and
connecting ports on the other end must be optical 4Gb FC LC compatible.
