D2D Design Considerations
D2D Port Optimization
The D2Ds have two 1GBit Ethernet ports, and some models also have two 4 Gbit Fibre Channel
interfaces. Correct configuration of these interfaces is important for optimal data transfer.
D2D Ethernet Ports
The Ethernet ports are used for both data transfer over the iSCSI protocol and management access
to the web GUI. The two ports have the following configuration modes:
•
Single port – Port 1 must be used for all data and management traffic.
Use this mode only if no other ports are available on the switch network or if the appliance is used
to transfer data over Fibre Channel ports only.
•
Dual port – Both ports are used, but must be in separate subnets. Both ports can access the web
GUI but virtual libraries are split across the two ports. Use this mode if:
