Networking
The DR appliance provides many networking capabilities, designed to further improve the ingest and
recovery speeds in any environment. One such feature is secure separation, allowing network
optimization by preventing unnecessary traffic on the production network via routing the backup,
management, and replication traffic to separate network interfaces. The DR appliance also supports a
multiple network interface cards, including 10GbE, providing features such as adaptive load balancing
and dynamic link aggregation. The following sections define the various options and configurations
associated with the DR4100, including steps to optimize the appliance to a given environment. As
always, the information provided below are guidelines and best practices that are meant to be
supplemental to the information provided in the DR administration guide.
Supported Network Cards
The DR4100 supports various network card configurations.. Both the 1GB and 10GB BASE-T network
cards support auto-negotiation which is enabled by default. The Broadcom 10GB SPF interface has the
ability to auto-negotiate when using the R8H2F transceiver.
When using the Broadcom 10GB SPF network interface card, ensure that the 10GB SR SPF+
Transceiver (R8H2F) is used. Failure to use the proper transceiver will result in errors on the DR Series
login screen.
The list of supported network card configurations for each DR model can be found within the Dell DR
Series System Interoperability Guide.
