Cabling to the customer’s Ethernet / IP Network

The DR550 provides for connecting to the customers Ethernet network using either 10/100 copper connections or gigabit fibre connections. For DR550 single node configurations, only one Ethernet connection is needed. For DR550 dual node configurations, four Ethernet connections are required (this enables HACMP failover if network problems occur). For the dual node configurations, two connections should be made to each of two customer provided subnets. Typically, it is expected that the customer will connect the DR550 to their existing network, including existing customer provided Ethernet switches.

Single Node Configurations

The following diagrams show the connections from an Ethernet perspective. With only one processing node, there is only a single Ethernet connection to the existing network. The type of connection (copper or fiber optic) is based on the adapter in the DR550. This choice is made when the DR550 is ordered.
